How to raise golden cicadas? What are the breeding methods and techniques of golden cicadas?

In fact, the golden cicada has not yet returned its shell, do not underestimate this golden cicada, golden cicada is particularly rich in nutrition, golden cicada is regarded as a famous dish in many places, and its meat is delicious. And the golden cicada is also of great medicinal value. With so many benefits, the golden cicada breeding project has sprung up rapidly. So how to raise golden cicadas? What are the breeding methods and techniques of golden cicadas?

1. Obtaining provenance

The primary provenance can be collected naturally in the field, and eggs, nymphs and adults can be collected as provenances. Various insect states can be collected from July to September; August to September is the best season to collect nymphs; September is the best time to collect branches of cicada eggs.

The artificial culture technology of golden cicada can be collected all the year round. The ideal place where there are many dense cicadas can be selected for egg collection. The 1-2-year-old thin withered strips on the tree that are killed by grasshopper cicadas are easily removed with fruit branch shears or long hooked poles at the top of the cicada. cicadas eggs are those whose one side is flat and dry and the surface is incomplete, and the subcutaneous xylem is embedded with a large number of milky long oval eggs, cutting off the superfluous withered shoots in the upper part of the spawning nest and leaving 10 centimeters and 15 centimeters of eggless branches in the lower part of the spawning nest mark. Tie about 50 pieces into a small bundle and put them in a plastic bag for use. The nymphs were captured and the naturally mature old nymphs were taken as the object. The nymphs could be captured by flashlight at the base of the tree trunk at 7: 12 in the evening; after collection, the nymphs were put into a gauze cage to feather and lay eggs. Shrubby hosts are planted in spawning cages, mainly a variety of fruit trees. There are many ways to catch cicadas on trees, such as using fire to trap them at night. In order to ensure that the adult cicada is not damaged, wheat gluten can be used. The method is to rinse the harmonious dough with water many times, remove starch, leave pure gluten, store it in broad lotus leaves and poplar leaves, stick to the top of the bamboo pole, and stick to catch adults in the early morning or during the day.

The collection of spawning branches should be taken as the main way to obtain provenance.

2. Reproductive species

The breeding objects are newly hatched nymphs and eggs close to hatching. The egg-bearing branches collected directly from the wild or in the provenance site are concentrated indoors to promote hatching. Hatching method: in the plastic box which is 70 cm long, 40 cm wide and 20 cm high, spread fine dry sand 5 cm to 10 cm thick at the bottom, put the egg branches vertically or horizontally on them, and constantly spray fog water with a small sprayer to maintain the high humidity of the air around the egg-bearing branches and make the excess water droplets adsorb in the fine sand at the bottom. In the middle, the hatching of eggs should be checked constantly, and when nymphs are found, the branches together with fine sand can be placed in the breeding site.

The ground under the host plant in the breeding place is about 1 meter away from the base of the trunk, digging regular narrow trenches with a depth of about 30 to 50 centimeters, such as ring, square, triangle, parallel or radiation, for the purpose of digging and harvesting in the future. The back cover soil of "breeding seed" is compacted, and the time, quantity, groove shape and depth of "breeding seed" are recorded.

From the egg stage to the growth and development of mature nymphs (cicadas), cicadas need to grow underground for three winters and summers (actually 2 years): the first year starts in June, the growth weight is only about 1 gram, and the whole body and eyes are milky white; in the second year, the body weight grew to about 3 grams, the whole body pigment deepened, and the eyes were pink. In the third year, the nymph (cicada turtle) matured, weighing 4.5 to 5 grams, with an average of 210 per kilogram, with brown body color and dark gray eyes. The time and age of nymph growth and development can be accurately judged according to the size of body weight, the depth of body color and the change of eye color.

3. Disease prevention

The main results are as follows: (1) there are many unearthed nymphs (cicadas) and adult natural enemies, such as toads, snakes, rodents, hedgehogs, wild cats, sparrows and mantis. Beauveria bassiana, Beauveria bassiana and parasitic algae (cicadas) are also parasitic. In addition, the pollution of floods and pesticides and chemical fertilizers do great harm to nymphs (cicadas) or cicadas, which should be paid attention to and protected when breeding.

(2) the most important seasons are the egg stage on the tree, the occurrence period of "cicada ants" and the unearthed period of mature nymphs. The natural enemies of egg stage and cicada ant occurrence period in trees are mainly ants and red flower bugs. The treatment measures are to use 100x solution of strong ammonia to wash egg branches or DDVP (organophosphorus insecticides), strong chlorine essence and so on for soil treatment.

4. Culture management

After the cicada eggs are buried in the ground, attention should be paid to drainage and waterlogging in the rainy season. Water white willow, willow or apple trees on dry days. At the same time of watering, we should also apply farm manure to promote luxuriant growth, provide sufficient nutrition for cicada larvae and young cicada monkeys, make young cicada monkeys grow vigorously, increase individuals and increase yield. It is necessary to strictly guard against the trampling of human and livestock and the infringement of natural enemies such as ants and moles.
