Artificial cultivation of white wax insects

The parasitoid is one of China's special resources insects. Paraffin is a wax produced by male parasitoids and processed to have a high melting point (81-85°C), stable performance, insolubility in water, moisture resistance, corrosion resistance, rust prevention, lubrication, lightening, etc. Important raw materials in the fields of defense industry, machinery manufacturing, textile printing, paper making, medicine, and cultural goods are also traditional export commodities of our country and have a good reputation in the international market. First, white wax insects and their parasitic tree white waxworm male adult wings, female adults without wings, the development of eggs, nymphs, adults and other periods. Each year, female adult eggs are laid in the month of 34, and the egg size is about 7,000 (a ratio of about 1:3). From April to May, the eggs hatched as larvae. The female larvae were dispersed and attached to the leaves. The male larvae colonized the leaves. After 20 days, the moltings became 2nd instar larvae. They left the leaves and attached to the shoots. The females dispersed males. Insects habitat. In the second instar male larvae, waxes can be secreted. In August, larvae were turned into adult males in early September. Adult females were found early to mate and died after 5-10 days. In August, female larvae of 2 years old became adults. After mating, the larvae gradually grew, and after winter, they arrived. The eggs were laid from March to April of the following year and died soon afterwards. The eggs in the egg shells are the white wax insects. Among parasitized parasitoids of helminthic parasites, privet is most suitable for breeding worms, and ash is most suitable for producing ash. Parasitic trees should be rotated in order to restore the tree vigor. Before and after the stocking technique starts in summer, they should be checked frequently and harvested in batches according to the maturity of the species. If parasitism trees are ready for rotation, they can be chopped to pick insects. If parasitism trees can continue to lay insects, they can be used to leave branching insects. The freshly plucked species shall be air-dried in a ventilated and dry place for 2-3 days. Then, a bag of 0.3 m in length and 0.25 m in width shall be made of sackcloth or brown pieces. Each bag shall contain 1.5 kg of insects. During transportation, ventilation should be done to prevent the sun from direct sunlight and make the temperature too high. If egg hatching occurs. The worms that have just been picked up or transferred back from the field should be selected for airing, drying, cleaning, and non-polluting indoor floors or racking. Use bamboo chopsticks to gently flip 2-3 times a day for breathability and evaporation. 10-15 days before the stocking of white waxworms, the branches and leaves of the ash trees should be trimmed so that the crowns are in order, the branches are evenly distributed, the air and light are good, the pests and diseases are reduced, and the management is easy. When pruning, if found on the tree with leaf bees, ladybugs and other pests, 10 days before the insects can be sprayed with 35% 223 emulsion 300 times; if there are pests such as cotton aphid, codling moth, etc., 90% can be used to crystallize the enemy Thousand insects 1000 times liquid prevention and control; eliminate predators in the forest. During the breeding season, when the female larvae (called "red worms") are mostly hatched and a few are crawling on the insect shells, they should be shed in time. Most of the materials use tung tree leaves, corn hulls, yellow esparto grass, etc., and 5 square centimeters large gauze worms can also be tested. Each insect pack can pack 2-3 species of insects and 4-5 species of medium breeders. After the bag is wrapped, it is air-dried for 2-3 days and it is tied to the worm-bearing tree. When the male larvae start hatching and shelling, they are also packaged in time. Fixed wax package, each package can be packaged with 20 large-grained species of insects, 25 species of intermediate species, 30 species of small-grained species. The movable wax packs can contain 20-30 pellets of large grained species, 30-40 grains of medium species, 50 species of small species, and then connect the two packages into a "group". Poke 3-5 holes on both sides and at the bottom of the wax pack to facilitate larvae to crawl out. After the wax bag is wrapped, continue drying for 2-3 days before hanging up the wax tree. When the hatching rate of the female larvae in the insect pack reaches 80% and the larvae crawl outside the pack, it is necessary to select 3-5 without wind and sunny day, and tie the insect pack to the tree before 10am. Most of the tree species are privets, the purpose is to produce eggs. The number of insect-bundles is generally 1 m long and 2-3 cm in diameter, and a pest package can be tied. The insect package is tied to the bifurcation of the 2-3-year-old branches about 1 m from the branches and close to the leaves. There are 2-3 twigs under the package, and the worms are evenly distributed on the branches, with appropriate weight. After 80% of the male larvae have hatched, they should also select 2-5 wind-free sunny days. Before 10:00 am, hang the paraffin tree or ash tree on the wax packet in order to produce white wax. To achieve the main branch more hanging, side branches less hanging, wax stick close to the stick, so as not to be blown off by the wind. Wax bales should be hung on the bifurcation of 1-2 year old shoots and near the leaves. On 1 meter long, 2-3 cm diameter branches, can hang 1-2 bags. After 1-7 days of bag attachment, male larvae should be regularly checked for the timing of removal and replacement. For example, if there are 6 full leaf male larvae on the ash branch with a length of 50 cm and a diameter of 2-3 cm, there are 7-8 male leaf larvae on the ash branches; similarly, there are 3 on the inclined branches of the big leaf ash. When the larvae of the leaf ash tree have 5-6 leafy male larvae, they should be removed. The females can receive the package within 10-15 days after the insect-bundle package, and the larvae receive the package after the leaves have been set. When the male adults begin to flee from the package, they should promptly recover the insect package and burn the wax.
