In the minds of many people, it is animals that eat plants, but the magical nature has subverted all this, because there are plants that eat animals, which is pitcher plants. As a mosquito repellent plant, pitcher plants can prey on mosquitoes, flies and other insects. Many people should know why pitcher plants eat insects. Follow a video of pitcher plants eating worms, and follow the editor to learn about it.

First, pitcher plants eat worms video 2, pitcher plants how to eat worms, natural digestion

The pitcher plant has obvious characteristics. It has a unique organ-the insect trap. The cage is cylindrical, the lower half is slightly inflated, and the bottle mouth has a lid, so named because it is shaped like a pig cage. As for how pitcher plants eat worms, it is very simple. Once bugs climb in, they will not be able to get out. They will gradually be buried in the bottom of the bottle and become nutrients for their growth.

Third, why pitcher plants eat worms, instinct

On this question, in fact, it is very simple, it is a kind of instinct. When the root system can not absorb nutrients from the soil, pitcher plants can only extract nutrients from the outside world in order to survive, and over time they have the ability to eat insects. We already know why pitcher plants eat worms, so why can they eat worms?

Fourth, why pitcher plants can eat worms, coordinate and cooperate

In fact, the pitcher plant can eat insects because of its unique pitcher cage. It is understood that the structure of this insect trap is relatively special, and its cage will emit a strange fragrance and attract mosquitoes and flies. Insects are attracted by the smell and stay on the lips of the cage, but they don't know that death is coming.

This lip of the pitcher plant can secrete juice and is quite slippery. Once touched, mosquitoes, flies and other insects will slide directly into the bottle. In the cage, the inner wall has a lot of wax, which is very smooth; there are about 1 million digestive glands on the inner wall from the middle to the bottom, which can secrete a large amount of colorless, transparent and slightly scented acidic decomposing liquid after the pitcher plant catches the worms. this digestive juice contains amines and alkaloids that can paralyze and poison insects.

At ordinary times, there is always about half a bottle of this digestive juice in the insect cage. At the same time, there are many nectaries on the inside and edge of the bottle cap, which can secrete fragrant and sweet honey to tempt insects. When the bottle opens the lid of the honeypot, it will attract a lot of gluttonous insects. Once the bug falls into the bottle, the cap will close automatically, and the insect will soon be poisoned and killed.

Soon, all the limbs were digested into hogwash and the nutrients were absorbed. Then the lid of the cage will open again, waiting to catch the next prey. Why pitcher plants can eat worms, we should know, aroma attraction, cage lips slippery, cage digestion, such a match, really make bugs feel scared!

Pitcher plants are just bugs. Pitcher plants are demons, attracting groups of companions to die in insect cages. As far as human beings are concerned, pitcher plants are rare plants that help us ward off mosquitoes in summer. So what are you waiting for? Quickly get a pot of pitcher plants to raise it. If you don't know how to raise them, you can also take a look at the breeding methods of pitcher plants, which will be helpful to you.

The counterattack road of insectivorous plants

Abstract: compared with animals, people usually tend to think that animals are the stronger and wiser ones: because plants are rooted in the earth and cannot move freely, they will be eaten by animals. But is this really the case? Can small potatoes, plants, who are regarded as the weak side, succeed in counterattack?

I like insectivorous plants, not only because of their cool hunting skills and beautiful appearance, but also because they are constantly staging stories of small potatoes counterattacking. It has a dramatic conflict effect when the roles of the predator and the prey are changed and the animals are reduced to plant food. To be able to perform this plot brilliantly on the stage of nature, it is the most star insectivorous plant in the plant world.

Make a way out of a predicament

Insectivorous plants are plants that can hunt and digest some insects and arthropods. There are about 600 to 750 species of insectivorous plants. Interestingly, although they all have the common skill of catching insects, they are very different in genetic relationship, coming from 10 families and 17 genera in the plant kingdom.

Due to the pressure of their own survival, insectivorous plants embarked on the road of insectivorous counterattack in their own way. In the vast land, not every inch is fertile soil, many places are sandy wasteland, alpine slopes and water areas where nutrients have been lacking for a long time. Various harsh and barren environments have set many obstacles for the survival of plants. For example, some seemingly luxuriant swamps, due to a long-term acidic environment, although the soil is rich in organic matter, it is difficult for bacteria to decompose into nutrients for plant growth; even in the tropical rain forest known as "animal and plant paradise", although nature is never stingy with sunshine and rain, under the fact that tall trees and dense layers of lianas occupy limited space and resources, various plants still have a fierce competition for survival.

The long-term lack of resources has made some plants learn to use delicious, protein-rich insects and other small animals as a new source of nutrition. However, although the animals are delicious, they are not lambs to be slaughtered. If they do not pay attention to tactics, the worms will not be at their disposal! Fortunately, the stage of nature is quite fair, and she gives these plants the opportunity to evolve freely under the strong pressure of survival. In the long road of evolution, these plants in different environmental regions have developed the best hunting tool with static braking-insect trap. These traps come in different forms but each has its own ingenuity, which fascinates countless scientists and plant enthusiasts.

A misstep is a bottomless abyss-- falling trap trap

There is a kind of insectivorous plant "do not move, do not shake" can catch insects and eat, its insect-catching artifact is a "trap" that makes the little ones fall and cannot climb out. This "trap" can be made up of all the leaves of the plant, such as some insectivorous plants of the pineapple family, which use the shape of the plant to surround all the leaves into a bucket-like structure, and the leaves at the top of the trap are extremely smooth. If the insect accidentally falls during the exploration, it will be killed by the liquid with acid and digestive enzymes at the bottom, and will be broken down and absorbed. There are also some more exquisite fallen trap insectivorous plants, such as Artemisia, pitcher and pitcher plants, whose single leaves are specialized to form a cage-like trap structure. In order to improve the predation efficiency of traps, these insectivorous plants perfect traps all the time, making the whole trap system a complex and efficient hunting machine.

In order to attract more insects, the pitcher-shaped traps formed by the leaves of these plants will secrete sweet nectar at the mouth of the bottle. In addition, mimicry is also a common means. For example, many bottle grasses can simulate the shape of flowers through the bright and changeable colors at the top of the trap, increasing the frequency of insect visits. Many kinds of pitcher plants are also masters of smell, which can simulate the smell of flowers and release substances similar to the scent of flowers to attract insects. Although the mechanism and form of insectivorous plant mimicry has always been a hot topic among scientists, there is no doubt that this "disguise" greatly improves the predation efficiency of traps. But successful attraction is only the first step, and it is also critical to successfully capture and trap prey. These insectivorous plants often leave a platform for flying insects to land, and when visiting insects land on the platform and begin to suck the honey provided by the trap, they step by step towards the edge of the trap. The fine hairs guiding downward are densely distributed under the edge, and if the gluttonous little guy stumbles, there will be a road of no return waiting for them. Eventually, in a highly efficient digestive juice filled with digestive enzymes and the remains of companions, the worms are gradually broken down to become "nutritional kitchens" for insectivorous plants.

A fatal kiss-viscose trap

As the name suggests, viscose traps are plants that secrete glue to trap their prey. This is also one of the most common forms of hunting in insectivorous plants. Such as pansy, flycatcher, pine and rattan plants, these plants often secrete a large amount of thick colloid or water drop-like glue or resin on the body surface, which can firmly absorb and capture the insects they come into contact with. Because such traps are often found throughout the plant, many species also have odor mimicry mechanisms that can release smells that fascinate insects, so they have high predation efficiency.

The drop trap has a closed pool that can protect its prey from being stolen easily. Plants with viscose traps are completely different, so they face the risk of food being stolen by other large insects or animals. Rain Water scouring and strong winds will also affect its gradual decomposition and absorption of insects. Don't worry, many species of viscose trap insectivorous plants have learned the skill of tightly wrapping and absorbing prey by curling leaves and tendrils after successfully catching insects, a process that usually takes a few minutes to days. Some of these species, such as acorn thatch, have tentacles that act like clever switches that curl and close to the center of the leaves in an instant, wrapping their prey tightly.

Unique shape-lobster basket type insect trap

Some of these traps are similar to falling traps, such as Cobra and Parrot pitcher grass, but they use a seemingly more elaborate trap. Unlike the spacious entrance of the drop trap, the top of the specialized abnormal blade is almost closed to form a spherical cavity, leaving only a small entrance. The delicacy of this kind of trap is that it takes advantage of the nature and weakness of insects, which is similar to the principle of catching lobster in lobster baskets.

Like many bottle grasses, lobster basket traps use colorful and varied leaves and sweet nectar to tempt insects, and when the attracted insects climb to the small entrance with the nectar, they will be induced by the gluttonous nature of drilling holes to find food and unwittingly climb into the hole. The cave is like a colorful small room, insects can not find an exit in this colorful psychedelic world, but can only follow the path provided by bottle grass, so they are doomed.

A rare Qigong-suction insect trap

This is the patented insect-catching technology of the aquatic insectivorous plant raccoon algae. Raccoon algae are usually small and can form miniature sac-like vacuum chambers no more than 10 mm in water. When food touches a specific switch, it is instantly sucked into the chamber by air pressure and slowly absorbed by raccoon algae. Raccoon algae is a kind of aquatic plant widely distributed in most parts of the world, and it is also a kind of insectivorous plant very close to our life, but it is a pity that its individual is usually very small, and the predation process in the water often ends in a few seconds. If we take a closer look at this process, we will see the excellent predation ability of this kind of insect trap.

A wonderful and intelligent trap-- an animal trap.

Insectivorous plants with trap traps may be the closest to imaginary insectivorous plants, and most of the man-eating flowers in many movies and comics have similar abilities. Once an animal touches a particular switch, a large mouth or a clamp full of spikes suddenly closes, clamping the careless animal in and eating it quickly. The source of this imagination is likely to be related to the real flytrap.

In the long-term evolution, the fly trap has a structure similar to that of an animal clip-a trap: the trap is two half-moon-shaped clamps with sharp thorns on the edges, and there are three slender and sensitive tentacles distributed in the clamp. once the prey continuously touches two of the hairs in a certain period of time, the clamp-like leaves can be quickly closed in 1/3 seconds, and the sharp thorns of the leaf edges are tightly linked to each other to form a cage-like structure. Lock your prey firmly in it. Gradually, the two leaves will be completely bonded because the insects in the prison continue to move and stimulate the leaves, and finally kill the insects and digest and absorb them.

The predation process of animal trap is not only wonderful, but also very intelligent. The trap opening and closing of the three tentacles can intelligently tell whether it is the interference of the wind and rain or the real insects falling into the trap. The spikes at the edge of the leaves can screen suitable prey when they are closed. if the fallen insects are too small and provide too little nourishment to close the leaves, then the insects in the cages formed by spikes can drill out and the traps will open again. Waiting for larger prey.

Semi-insectivorous plant

Nature is magical. In addition to the known insectivorous plants, many other plants are on their way to insectivorous plants, while some insectivorous plants seem to have reached the end of carnivorous food and returned halfway back.

There are not a few plants that can catch insects, such as the dragon bead fruit of Passionaceae. During the fruit growth period, a viscose network structure similar to thatched vegetable is formed around the fruit, which is used to catch small insects. In recent years, some scientists have confirmed that this structure can not only capture insects, but also secrete digestive enzymes to digest and absorb prey. However, the dragon bead fruit is still a non-traditional insectivorous plant, the study found that: this predation mechanism and structure is more significant to protect the fruit from insects. Scientists speculate that in the process of evolution, if the environment in which the dragon beads are located is poor in nutrients, then this trap mechanism for catching insects may be further strengthened, resulting in the evolution of more sophisticated and efficient traps for predators. Further towards insectivorous path.

There are many such plants that can catch insects, such as Parthenocissus, Insectivora, some pineapple family, Dipsacus, and so on. However, perhaps because they cannot secrete digestive enzymes, or because the traps are not specialized enough, the behavior of catching insects has a low weight in the process of their growth and breeding, and such plants are not included in the traditional list of insectivorous plants. They seem to be on their way to becoming insectivorous plants from far to near.

Interestingly, even at the end of the road to insectivorous plants, some insectivorous plants seem to have gone back on their promises, finding that carnivorous food is not necessarily the best choice. Although some insectivorous plants have excellent predation organs, they have chosen a path that seems to return in the long process of evolution. For example, the apple pitcher plant of the family pitcher plant family, a famous insectivorous plant family, chose to be a vegetarian. Although it still has a pitcher-like trap, it no longer secretes protein digestive enzymes inside, but opens its mouth to the sky, relying on digestion and absorption of fallen leaves to replenish nutrients.

Other famous large pitcher plants, such as Lloyd's pitcher plant and royal pitcher plant, are likely to choose to eat dung, and their traps secrete honey and attract small animals such as tree shrews to lick them. Lloyd's pitcher plants and royal pitcher plants, which are not meant to drink, take the opportunity to provide natural "toilets" and use the droppings of animals as their own nourishment.

One trap, one world-symbiosis

On the way to insectivorous plants, most of the time they are not alone. Choosing a suitable animal partner will bring unexpected benefits to both sides. Many insectivorous plants have found many such companions in the long process of evolution, which makes their insectivorous life more wonderful. This mutually beneficial symbiotic relationship exists widely in insectivorous plants.

The symbiotic relationship is particularly prominent in pitcher, pitcher, pitcher and pineapple families. Private water tank traps provide a convenient environment for the survival of many animals and opportunities for mutual benefit and mutual assistance with insectivorous plants. Some bottle grass plants themselves can not secrete digestive enzymes or a small number of digestive enzymes, can not directly decompose prey, but with the help of benthos living in the pool, they can solve this problem very well. Some Chironomus larvae and North American bottle mosquito larvae will eat the prey and break it down into pieces, and the bacteria in the bottle will eventually break it down into nutrients that can be directly absorbed by bottle grass, benefiting both landlords and tenants. The "pitcher" of vegetarian apple pitcher plant is a mini-world. The fallen leaves become food for some bacteria and vegetarian insect larvae, and these larvae become food for insect larvae such as tadpoles and giant mosquito larvae. Apple pitcher plants also absorb the corresponding nutrients in the process. The small and medium-sized world of the bottle has become a self-contained ecological chain, even forming many species that are unique to this biological chain.

Ants are one of the most common prey insects in pitcher plants. They are often attracted by the nectar secreted by pitcher cages and thus become prey. However, one species of bow-backed ant cleverly chose to have a mutually beneficial symbiosis with Borneo's two-toothed pitcher plant: the hollow tendrils of the pitcher plant provide shelter for the ant, and the ant feeds on trapped large insect or mosquito larvae. On the surface, ants seem to plunder some of the plant's prey, but both opposites are profitable, so they reach a dynamic balance. If the cage catches larger prey, the oversized carcass may exceed the digestive capacity of the cage, and the Archback ants can help carry the extra prey, thus keeping the digestive system of the cage intact. Ants can also clean the traps for pitcher plants, keep the edges of the bottles smooth and protect them from being disturbed by other animals; in return, ants have a relatively comfortable home.

Sapporo (an insectivorous plant) is a good partner to work with stinging bugs to hunt. Insect catching can be up to several meters high, and the whole body is covered with strong mucus similar to resin, which has a very high insect catching efficiency. But it cannot secrete digestive enzymes and cannot digest the prey it catches. Don't worry, in the long-term evolution, the cooperation between Sapporo and stinger bugs has successfully solved this problem. The stinging bug has evolved a unique wax to ensure that it will not be stuck by the resin of the insect trap, so that it can travel freely in the scary slime forest, but the insects caught by other captured insects will become a cheap meal for the stinging bug. In return, the stinging bug's digestive tract digests its prey and excretes the highly efficient organic fertilizer that is easy to absorb on the insect-catching branches and leaves for its absorption.

In fact, the relationship between insectivorous plants and prey insects is often complex, many still need to be studied, and there are many interesting phenomena that fascinate and debate serious scientists. For example, some bottle grasses, many scientists believe that they have a mutually beneficial relationship with the captured insects: bottle grass has long provided some insects with honey, a rare and efficient energy drink in the swamp. the price paid by the whole insect population was only at the expense of a small number of individuals to provide a source of nitrogen for bottle grass, but the two sides provided each other with the scarce goods they needed. This seemingly dangerous hunt is actually a win-win!

Of course, the relationship between animals and plants on the road to insectivore is not necessarily harmonious, and there are also many seemingly one-sided biased relationships: for example, many ants will impolitely and quietly snatch away the prey captured by pansy, leaving no nutrition; green cat spiders can directly drag some insects that fall into bottle grass and eat them; and pitcher plant flower spiders have learned to lurk near pitcher plants and catch insects attracted by traps. According to current research, none of these behaviors seems to bring any substantial return to plants.

The road to the future

The insectivorous evolution of insectivorous plants is very interesting, which comes from four different plants of pineapple family, pitcher plant family, pitcher plant family and pitcher plant family, which have evolved trap structures with similar appearance and function under different environments and different origins. On the other hand, the genera raccoon algae and flycatcher, which belong to the same family, are gradually far away from the same family, and gradually evolve in different directions, and there are great differences in appearance and predation mode. The most popular mucus-secreting traps in plants come from different families, such as Castanopsis, Insecta, Pinus, Leaf, and so on, but because of their similar predation patterns, many morphological characteristics tend to be similar. As for the future, the evolution of insectivorous plants still has a long way to go, and more hunting methods and mechanisms need to be explored.

At present, human knowledge about insectivorous plants is very limited, and there are many species that may become extinct before we fully understand them. According to IUCN, more than half of all insectivorous plants are threatened with extinction. These threats come from all aspects, in addition to the changes in the natural ecosystem, they are also closely related to human activities. for example, with the increase of population, land reclamation continues to erode the habitats of insectivorous plants; environmental pollution will also destroy the living environment of insectivorous plants The preference of some plant lovers to cultivate insectivorous plants will also lead to the excavation or destruction of a large number of wild insectivorous plants, which may lead to the risk of extinction of insectivorous plant populations.

What are the mosquito repellent plants?

[FAQ] which plants have the effect of repelling mosquitoes?

[expert answers]

1. Evening incense

Night incense, also known as nocturnal incense, is found in tropical America and the West Indies and belongs to the genus Solanaceae. Perennial evergreen semi-vine soft shrub, 2 m-3 m high, trunk grayish brown, smooth, branches multi-lateral, soft and drooping. Leaves alternate, slightly narrow, heart-shaped, apex pointed, entire, thin and soft, margin pilose. Corymbose Cymes, axillary or terminal.

Evening incense elegant and beautiful, easy to cultivate, the price is not expensive, coupled with the summer blossom when green and white, it is easy to cool. The aroma of flowers such as nocturnal incense is often refreshing at first, but it may have an uncomfortable reaction because it is too strong for a long time. Night emits a strong fragrance, mellow and intoxicating, but this fragrance scares mosquitoes and is a good product to ward off mosquitoes.

2. Lavender

Lavender is a fragrant purple flower, also known as "tranquil perfume plant", known as "aromatic herbs". Lavender grasslands are produced in the Mediterranean region, such as Provence, France, and are widely cultivated in Britain and Yugoslavia.

The flower language of lavender means "fragrant". When you go to the lavender field, you will often be unwittingly attracted by its special aroma, so lavender is also known as "after vanilla".

Lavender itself has an insecticidal effect. People usually put sachet made of lavender in cabinets, and some put it in the bedroom to ward off mosquitoes.

3. Pitcher plant

Pitcher plant is a famous tropical insectivorous plant, whose origin is mainly in tropical Asia. The pitcher plant has a unique nutrient-absorbing organ-the insect trap, which is cylindrical in shape, slightly inflated in the lower half, and has a lid on the mouth of the cage. It is called pitcher plant because it is shaped like a pig cage. In Hainan, China, it is also known as Lei Gong kettle, which means it is like a wine pot. Pitcher plant is one of the insectivorous plants because of its poor native soil and supplementary nutrition by catching insects and other small animals.

There are dozens of kinds of pitcher plants, and the shape, size and color of the pitcher bottles are also different. Pitcher plants can be used medicinally and have certain curative effects on diseases such as hepatitis, stomachache, high blood pressure and colds.

4. Geranium

Geranium, alias stone red, red red, sunflower, sunflower, is a genus of flowering plants, including about 230 species of perennial succulent, subshrub or shrub plants. Geraniums are native to southern Africa and are widely cultivated all over the world. The young plants of Pelargonium are fleshy herbs and the old plants are semi-lignified; the leaves are opposite, round, kidney-shaped or fan-shaped; the flowers are white, red, purple, pink, orange and so on, which are umbels, which can blossom in all seasons and reach the peak in spring. Geraniums are good windowsill flowers in the West, especially in continental Europe, such as Germany and Austria.

In the hot season, put the outdoor shade environment; in the cold season, watch it in the bright room. Geraniums have a unique smell that makes mosquitoes and flies escape.

5. Seven Lixiang

A plant with fragrant leaves shaped like peas. The ancients used it to collect books, to avoid beetles, and to remove fleas under mats. Touch its leaves, will feel a strong sweet smell, mosquito repellent effect is very good.

6. Cordyceps sinensis

Cordyceps sinensis is a herb of the family Compositae, which can grow to 1 meter tall with small yellow flowers. There are hundreds of flower heads in one plant, and there is mucus on the periphery of each flower head. As long as a small mosquito falls on it, it is stuck, and the insect body is slowly digested as its growth nutrition. If there is dust sticking off the top a few days later will be digested, a pot placed in the home can catch mosquitoes and vacuum.

Cordyceps sinensis is a plant that grows in the marshes of North America and suffers from lack of nutrients for a long time. Because the extremely humid land here has been occupied by a plant called peat moss, which can only get water from rain and snow that fall directly on the stems and leaves. The carnivorous habit of Cordyceps sinensis is gradually formed under such a living condition.

7. Mosquito repellent grass

Mosquito repellent grass has the smell of lemon, raised in the house, mosquitoes will escape. The reason is that mosquito repellent grass contains a special "small raw material", which uses transgenic technology to insert the structure of citronellal gene into "vanilla" and uses its own unique release system as a carrier. the citronellal substance is continuously released into the air. At the same time, plant DNA (gene) structures with fresh odors and air purification are implanted to form a "natural evaporator", resulting in fragrance. Especially in hot summer, it will be refreshing and refreshing. After testing, its mosquito repellent effect is good, harmless to human beings and animals, and can ward off hundreds of mosquitoes. Mosquito repellent is a perennial herb with a living temperature above minus 3 degrees Celsius and can be cultivated both indoor and outdoor. In general, the higher the temperature, the stronger the fragrance, the better the mosquito repellent effect.

8. Chasing flies and plums

The sensitive smell of mosquitoes and flies is volatilized from its branches, leaves and flowers, which has a strong effect of expelling mosquitoes and flies without any harm to the human body. It not only has a good effect on repelling mosquitoes and flies, but also has beautiful colors such as red, yellow and white. The flowers are often yellow or pink at first, then gradually become orange or orange, and finally red, so they are known as "mosquito repellent seven flowers".

9. Mosquito clean vanilla

Mosquito net vanilla is an aromatic geranium plant that has changed its genetic structure and was introduced from Australia. The plant is drought-tolerant, can grow and mature within half a year, and can survive for 10-15 years if properly maintained, and the shape of its branches and leaves can be changed at will, so it has high ornamental value. Mosquito net vanilla exudes a fresh and elegant lemon fragrance, which has a good mosquito repellent effect indoors, but has no toxic side effects on the human body. The higher the temperature, the more incense it emits, and the better the mosquito repellent effect. According to the test, a pot of mosquito net vanilla with a crown width of more than 30 centimeters can drive away mosquitoes in a room with an area of more than 10 square meters. In addition, a plant called pyrethrum contains pyrethroid, which can also effectively ward off mosquitoes.

10. Marigold

Marigold is an annual herb and an ideal raw material for extracting pure natural yellow pigment. It is called kakibusch in Africa. It is commonly seen hanging from indigenous huts to drive away swarms of flies. Marigold has a pungent smell, mosquitoes do not dare to approach it, is a special and excellent natural insect repellent.

11. New mosquito repellent trees

The new mosquito repellent tree belongs to the deciduous tree of Rutaceae, which is a new species of mosquito repellent tree discovered and launched in recent years. It uses the unique citronellal substance on the leaf surface to be emitted into the air through high temperature evaporation to achieve the effect of repelling mosquitoes.

12. Plane tree

Plane tree in the growth process, the bark will slowly fall off, and the shedding dry bark is a good mosquito repellent thing. The dry bark of some plane trees can be collected and lit together. The smoke produced when burning has a faint fragrance, which can drive away mosquitoes. In the past, the production of old-fashioned mosquito-repellent incense in rural areas was mixed with sycamore bark. Note that it is not suitable to be used in enclosed rooms.

13. Other mosquito repellent plants

In addition, moxa leaves and jasmine flowers can repel mosquitoes. Use Ai Chao once to make it "strong". Artemisia argyi not only treats a variety of diseases, but also has a peculiar fragrance, which can be used as a raw material for flavoring. Branch and leaf fumigation can drive mosquitoes and flies and has the efficacy of poison and sterilization. Safe record Ai Xiang mosquito repellent lotion is extracted and its essence is used to repel mosquitoes and relieve itching.

Conclusion: the above editor introduces more than 10 kinds of mosquito repellent plants, which are harmless to the human body, but can drive away insects at the same time. There are the most mosquitoes in summer, and mosquito repellent plants in pots are not afraid.
