The scientific name is Polyphagotarsonemus Latus (Banks). On the side of the alias, there are more food crickets, yellow tea pods, tea semi-finance lines, and tea leaves. The host cucumbers, tomatoes, eggplant, green peppers, kidney beans, beans, potatoes and other vegetables. The fields are identified as contractures and larvae are concentrated on the young part of the crops. The back of the affected leaves is gray brown or brownish brown, with oily luster or oil immersion, and the leaves are curled downward; the affected stems and shoots Turn yellowish-brown, distorted deformity, severe plant dry at the top; affected buds and flowers, in serious cases can not flower, fruit set; fruit victim, fruit handle, respect piece and peel into brown, loss of luster, corkification, and finally Cause eggplant cracking, flowering bread-like, bitter and astringent, unbearable. Seriously affected people suffered from falling leaves, falling flowers, and falling fruit, which resulted in a significant reduction in production. Affected tomatoes, the leaves are narrow, stiff and upright, shrinking or distorted, and finally bald. Since the carcass is extremely small and difficult to observe and recognize by the naked eye, these characteristics are often mistaken for physiological or viral diseases. The morphological features of the female skeleton is about 0.21 mm long, oval, wide, and the abdomen is truncated. Light yellow to orange yellow, thin and transparent epidermis, so the corpus callosum was translucent. There is a longitudinal leucorrhea on the back of the body. The feet are shorter, and the fourth pair is slender. The ends of the knot are end hairs and sub-hairs. There are 4 pairs of bristles in the ventral hind foot body. Pseudo-valve organs expand toward the back end. The male is about 0.19 mm long. Forefoot has 3-4 pairs of bristles. There are four pairs of bristles on the ventral surface of the hind foot. The feet are long and thick, and the base sections of the third and fourth pairs of feet are connected. On the 4th pair, the foot and intestines are slender and the joints are bent to the inside. The distal one-third has a particularly long whip hair, and the claws degenerate into buttons. Egg oval, colorless and transparent, the surface with longitudinal columnar protrusions. There is a white longitudinal band on the back of the reptile, and a pair of bristles on the end of the abdomen with 3 pairs of 8 feet. If the ellipse is a stationary growth stage, it is covered with the skin of the pup. The law of occurrence can occur throughout the year in tropical and greenhouse conditions, but the winter breeding capacity is low. In the Beijing area, greenhouses began to occur in late May, and from late June to mid-September, they were the most prosperous period. Exposed vegetables were heavily damaged in July-September and eggplant peaked in mid-August to early September. In winter, wintering occurs mainly in greenhouses, and a few female adults can overwinter in winter crops or weeds. The main part of sexual reproduction is also partial female reproduction, but the hatching rate of fertilized eggs is low. Eggs are spawned on the back of young leaves, young fruit indentations or young buds, hatched after 2-3 days, young pupa period of about 2-3 days, if the flood season 2-3 days. The optimum temperature for the development and reproduction of the tea plant was 16-23°C and the relative humidity was 80-90%. The developmental period of generations is 28-30°C, 4-5 days, 18-20°C, 7-10 days. Into a lively, especially male, when the feeding site grows old, it immediately shifts to the new young site and carries the female. The latter, after one skin becomes a beak on the male skeleton, mates with the male and settles down on the young leaves. Because of this strong tenderness, it is called a young leafhopper. Eggs and larvae have high humidity requirements and can develop only when the relative humidity is above 80%. Therefore, a warm and humid environment is conducive to the occurrence of ochre. Prevention and control methods Astragalus membranaceus has a short life cycle and strong fertility. Special attention should be paid to early prevention and control. The first time for various crops is: green pepper for the end of May and early June; late spring and early summer eggplant for the end of June and early July; summer sowing eggplant For the end of July and early August, or the first time in the first flowering time, once every 10 days, after continuous control 3 times, can control the damage. The following agents and concentrations can be used: 20% Chloramine EC 2000-3000 times, 73% Ketel EC 2000 times, 25% Chlortetramotent 1000 times, 5% Nicoroxide 2000 times, Killing (21% synergistic Cyanol EC) 2000 times solution, Uranus (bifenthrin, 2.5% EC) 3000 times solution, 25% synergistic quizphos EC 800-1000 times solution are all effective.
