Morphological characteristics Adult body length 40 to 48 mm, 125 mm wingspan. All black, shiny, with a metallic luster. Compound eye light auburn. There is a yellow-brown patch on the center of the front edge and on the cheeks. The middle thoracodorsal plate is large, with a tan-colored "X"-shaped ridge in the center. Before and after the wings are transparent. The front wings are yellowish-brown at the front, black at the base, black at the front of the front wing, 1/3 black at the base of the forewings, and the base of the wing is black with a light yellow-brown spot; the base of the hind wings is 2/5 black, and the veins are light yellow and dark black . Feet pale brown. The first and second quarters of the male's abdomen have mas- ters, females have no sirens, there are hearing devices, the ventral valve is not well developed, and ovipositors are prominent and well developed. Eggs long and elliptic, slightly curved; ca. 2.5 mm long and 0.5 mm wide; milky, shiny. The nymph is yellowish-brown, with winged buds, capable of crawling. The forefoot of the first instar is clearly digging; the last-instar nymph is 35 mm in length and yellowish-brown. The front foot is digging and the wing buds are well developed. The value of economic resources is the value of food. According to scientific analysis, wolfberry is rich in amino acids, proteins and trace elements, and essential amino acids account for 46.63% of total amino acids. In addition to having food value, it also has medicinal functions. When the mature nymph is changed to adult, the outer shell of the eclosion is called quail, also known as è‰ è‰ â€ or è‰ è‰ , ,. Its main components are chitin and protein, sweet, salty, cold, into the lungs, liver Jing, is an important Xin Liang Jie table Chinese medicine. Fresh nymphs and adult nymphs, especially nymphs are not only nutritious and delicious, but also have very high medicinal value.
The natural habits of crickets are generally completed in 1 to 3 to 5 years, and there are also records of 1 to 5 to 6 years or 12 to 13 years. The overwintering states are nymphs with two different eggs and sizes, and the overwintering sites are divided into two kinds: above ground and below ground. The overwintering states are wintering on young shoots of the same year or two years old and young nymphs of all ages. surroundings. The wintering eggs begin to hatch in mid-May of the following year, and the incubation period is from late May to early June, and the hatching activities are completed at the end of June. Eggs hatch more during the day and afternoon, accounting for about 80%, and there is less hatching at night, about 20%. The egg period is close to 300 days. The activities of overwintering nymphs are most affected by the temperature and the host plant sap. When the temperature is higher than 10°C-15°C, the sap of the tree begins to flow, and the overwintering nymphs begin to suck and feed. The nymphs hatched from the wintering eggs (called ants) are immersed in the soil and suck sap at the roots of the host plants, which is less active.
As the age grows, earthenware chambers of different sizes and shapes are created and inhabited. The surface of the earth is rough, and the inner wall is smooth and moist. A part of the wall adheres to the root of the plant for feeding. After the fall, the temperature dropped, and the soil was drilled into the deep soil. After spring, it migrated upwards to the activities near the roots. The number of nymphs in the soil in May is the highest in the year. In this case, a large number of overwintering eggs are hatched into the soil, and it is a time when the last-instar nymph is about to emerge into adult moths. After completing the whole life process of the nymph in the soil, the mature nymphs drilled from the soil from late May to late August, and crawled to shrub branches, weed stems, etc., and fixed to the tree with claws and forefoot stabs. On the branches of the skin, moltings become adult. From mid-June to mid-July, the emergence period of adults is high, and early October is the final period. About 20 days after adult emergence, the oviposition spawned, and spawning began in late June. The end of June to late August was the fecundity of adults, and the end of spawning was from early September to early October. The final stage of the adult is early November. That is, the adult's spawning period can last from late June to early October. Adults mostly emerged at 8 to 10 o'clock in the night and 4 to 6 o'clock in the morning, and the male to female ratio was maintained at a ratio of 1:1.
Adults often inhabit the branches of trees and have the habit of fighting fire at night. Adults spawn in one or two years old, 2 to 7 mm thick branches, the eggs are produced in the xylem branches, nests close together, mostly single, double, straight line, a few curved or spiral . There are 6 to 8 eggs in each nest, and there are 12 to 479 eggs in a spawning branch, usually 20 to 200, and an average of 146 eggs. There are 6 to 146 ovary points on each branch. Each female has more than 500 to 1000 eggs in its abdomen, up to 1500 and at least 20, with an average of 800. Adult life is about 3 months, and the occurrence period is generally from July to September each year. Adults have wings and can fly. They suck on the nutrient sap from the young shoots of trees. After mating, female ovipositors use an ovipositor to insert into the xylem of the first year or two years of mature branches before laying eggs. At the same time, the twigs are dehydrated and dried to death, causing damage to the trees.èš±è‰ likes woody, juicy trees, such as hawthorn, peach, apple, and eucalyptus.
For the successful breeding of earthworms, the following points should be mastered: access to seed resources, selection of host plants, selection of breeding grounds, and configuration of protective measures.
1. Obtain access to primary provenances of provenances can be collected naturally in the field. Eggs, nymphs, and adults can be collected as seed sources. From July to September, each insect state can be collected; from August to September, it is the best season to collect nymphs; in September, it is the best time to collect the cilia branches and can be collected throughout the year. The collection of eggs can be done in an ideal place with many dense branches and trees. The 1-2 year old stems and stems that are killed by the spawning of eggs on the tree can be removed lightly by using branches or hooks. The sides are flattened. Dry and incomplete surface, the invader of the xylem with a large number of milky oblong eggs is the lice eggs, cut off the excess eggless shoots in the upper part of the spawning nest, leaving 10-15 cm in the lower part of the spawning nest marks , bundle 50 or so small bundles into plastic bags and wait. The capture of nymphs is based on naturally matured mature nymphs. The collection of nymphs can be captured by hand-lighting at the base of the tree from 7 to 12 o'clock in the evening. After collection, the nymphs are placed into cages for emergence and spawning. Planted shrub-like hosts in spawning gauze, mainly fruit trees. There are many ways to catch a tree on a tree, such as using a fire trap at night. In order to ensure that the loquat is not damaged, the wheat gluten can be used for sticking by repeatedly washing the dough with water, removing the starch, leaving pure gluten, and storing it in a wide lotus leaf, poplar leaves, sticking to the top of the bamboo ,adsorption of adult worms in the early morning or daytime. The collection of spawning shoots should be used as the main approach to obtaining provenances.
2. Incubation species are newly hatched nymphs and closely hatched eggs. Eggs collected directly from the field or on the provenance site will be concentrated in the room to promote hatching. Incubation method: In a plastic box 70 centimeters long, 40 centimeters wide, and 20 centimeters high, spread 5 to 10 centimeters thick fine sand on the bottom, and put the egg branches in bundles horizontally or horizontally on it, and keep using them. The sprayer sprays fog water and maintains the high humidity of the air around the twigs so that excess water is absorbed in the bottom fine sand. In the middle, eggs should be continuously inspected for hatching. When nymphs are found to be active, the shoots can be placed on the breeding site together with fine sand. The breeding time is generally from September to October (two-year egg) or from June to July (the year of egg). Under the host plant of the breeding site, the ground is about 1m away from the base of the trunk. Excavate about 30 to 50cm of regular narrow ditch, such as rings, squares, triangles, parallels, or radiation, for the purpose of later excavation and catching. Received. After the “seed plantingâ€, the cover soil is compacted, and the time, quantity, and “growing†groove shape and depth are recorded. From the beginning of the egg period to the maturity of the nymph (known as a turtle), it is necessary to grow three winter and summer conditions (actually 2 years) in the ground: the first year starts from June and the growth weight is only about 1 gram. The whole body and eyes are milky white; in the second year, the body weight develops to about 3 grams, the body pigment deepens, and the eyes become pink; in the third year, the nymphs (know turtles) are mature, weighing 4.5 to 5 grams, with an average of 210 per kilogram, At this time the body is brown in color and the eyes are dark gray. According to the size of the body weight, body color depth and eye color changes, you can accurately determine the time period of nymph growth and development.
