Are cicadas, locusts, flying moths and bamboo insects pests or beneficial insects?

Insects have many kinds and different shapes. They belong to arthropods among invertebrates. They are the largest animal group on the earth. Common insects include cicadas, locusts, moths, stick insects, etc. Many people do not know whether these insects are pests or beneficial insects. Let's go and have a look together!

1. Cicada

Cicada commonly known as the (leech) or borrow the son. Cicadas usually live in temperate to tropical regions of the world, a few distributed in desert areas, is the insect class Hemiptera Cervicorhynchus Cicadae insects, larvae live in the soil, belong to incomplete metamorphosis insects, larvae eat plant roots, adults eat plant juice.

Cicadas are beneficial insects or pests

Cicadas are pests. Cicadas are harmful to plants all their life. They are tree destroyers. They insert their needle-like mouths into tree branches to suck plant sap to maintain their lives. After mating, female cicadas also insert their spear-shaped ovipositor into the xylem of young branches to lay eggs. Once inserted, they will make a hole. Many small holes are often inserted into a branch. After laying eggs, they will pierce the lower part of the branch with their mouthparts, so that the upper part of the branch will not get water and nutrients. Finally, they will die. The dead branches fell to the ground as soon as the wind blew. After hatching into a nymph, the egg burrows into the soil and begins to live a long underground life. It absorbs the sap of the roots underground for a living. It takes at least two or three years to 17 years to live enough underground before it climbs out of the ground. Then, it "sheds its shell" and emerges into a cicada.

How long does the cicada live?

Different species of cicadas have different life cycles. The life cycle of French cicadas is mostly 4 years, while North American cicadas have a life span of 17 years. The life cycle of Chinese cicadas is mostly 3 to 7 years, nearly half of which is 5 years, and a few can spend 8 to 9 years.

What food do cicadas eat?

Cicada larvae live in the soil, using piercing mouthparts to suck plant root sap, usually staying in the soil for several years or even more than ten years, such as 3 years, 5 years, and 17 years. Adults sing in trees in summer, sucking sap from trees with needles.

2. Locust

Grasshoppers, grasshoppers, grasshoppers, etc., are the general name of Orthoptera animals, distributed in tropical and temperate grasslands and desert areas all over the world. There are more than 10000 species in the world, and there are more than 1000 species in China. Among them, East Asian migratory locust has the widest distribution range and the most serious damage in China.

Are locusts beneficial or harmful?

Locusts are agricultural pests. Locust is an important part of agriculture, forestry and animal husbandry ecosystem. Many harmful locust species can cause different degrees of harm to agriculture, forestry and animal husbandry. There are more than 10,000 species of locusts in the world, among which about 300 species can cause harm to agriculture, forestry and animal husbandry. Locust can occur all over the world except Antarctica and Eurasia north latitude 55°. Locust infestation covers an area of 46.8 million square kilometers all year round in the world, and 1/8 of the world's population is often disturbed by locust infestation.

3. Moths

Moth is a general term for insects closely related to butterflies. Both belong to Lepidoptera. Most of them spread their wings on both sides of the body when they are still. They have eye-like patterns that can deter enemies. They are mostly active at night and like to gather in bright places. Therefore, there is a saying in folk proverbs that "moths burn themselves to the flame".

Are moths beneficial insects or pests?

Moths are pests. Moth larvae have chewing mouthparts and feed on plant leaves. They are important pests of agricultural and forestry crops, fruit trees, tea leaves, vegetables and flowers. Adults are unable to chew food, but suck sap, nectar, etc. with long mouthparts similar to straws. Some species will also knot sheath or spinning net, etc. Some drill into plant tissues to harm, dive into mesophyll, drill into stem. Some invasion borers bud, flower, seed and other tissues, sometimes can also lead to gall. Soil-dwelling larvae eat plant roots and become important underground pests. Species that damage stored grain, goods, or fur are important warehouse pests. A few species are predatory, preying on aphids or scale insects, such as aphidophagous gray butterfly is the natural enemy of sugarcane cotton aphid.

4. Stick insects

Stick insects are medium or large insects of Orthoptera. They are named for their slender bodies. They have wings or no wings. Most of them are dark brown, and a few are green or dark green. They inhabit mountains, dense forests and complex habitats. They have typical mimicry and protective colors and are not easy to be discovered by enemies.

Is stick insect a pest or a beneficial insect?

Stick insects are pests. Stick insects live in forests or bamboo forests, herbivorous, can harm plants, feeding time can be seen in the day and night, but most of the evening feeding and activity. Especially in Oceania, several stick insects often occur in large numbers and eat eucalyptus leaves. There are also reports of damage to oak trees and disasters in China.

What natural enemies do stick insects have?

green Hornet

Green bees, also known as cuckoo bees, red tail bees, etc., are mostly distributed in parts of North China. The way of laying eggs is strange. Qingfeng lays its eggs in the nest of bees and wasps or on the skin of other larvae. After hatching, the larvae usually eat the food in the hive and even eat the small larvae of bees and wasps. Scientists call this phenomenon "nesting eggs."

Crows

Crows are birds belonging to the genus Crow, Passeriformes, family Crow. They are omnivorous, many species like to eat carrion, and have certain harm to seedlings and grains. But in breeding period basically feed on small-sized vertebrate, locust, mole cricket, chelonian shell and moth kind larva, beneficial to farming. In addition, due to its love of scavenging and pecking agricultural waste, it can eliminate environmental pollution such as animal carcasses and play a role in purifying the environment.

Capuchin

Curled-tail birds inhabit tropical broad-leaved rain forests in mountainous areas. They live in open grasslands, open river banks in valleys or wet swamps. They mainly feed on insects such as locusts and grasshoppers, as well as flowers and berries of plants. It often stays at the top of isolated trees for a long time, sometimes flying suddenly to catch insects flying in the air, or flying through dense trees.

ant

Ant is a kind of insect, there are many kinds, there are more than 11700 kinds known in the world, and there are more than 600 kinds of ant species identified in China. The life span is very long, worker ants can live for a few weeks to 3~10 years, queen ants can live for several years or even ten years, an ant nest can grow for several years or even ten years in one place, it should be noted that termites do not belong to ants.

Spider

Spiders are the most abundant predatory animals in the terrestrial ecosystem. They are the general name of all species of arachnida in arthropod phylum. They are distributed all over the world except Antarctica. They play an important role in maintaining the stability of agricultural and forestry ecosystems. They mostly feed on insects, other spiders and polypods. Some spiders also feed on small animals.

Mantis

Mantis is a terrestrial predatory insect (carnivorous), which is widely distributed all over the world except polar regions, especially in tropical areas. All small species of insects can be preyed on by mantis, especially flies, mosquitoes and locusts. The eggs, larvae, naked pupae and adults of butterflies are suitable prey, and even large insects such as cicadas and migratory locusts are their prey.

Tree-lizard

The chameleon is a reptile belonging to the genus Tree Lizard of the iguana family. It inhabits tropical and subtropical areas and is common in forests, hillside grass, cemeteries, rivers, roadsides, grass or tree trunks near houses. It has strong adaptability and is not affected by human activities. Its survival altitude range is 80 to 2000 meters. It mainly consists of insects and small vertebrates, including rodents and other lizards.
