Host cotton, eggplant, strawberry, beans, watermelon, loofah, pepper, scallion, ginseng, leeks, apples, pears, tea, mulberry, sorghum, alfalfa, cherry, alfalfa, willow and grass weeds.
Injury characteristics, if Ruocheng inhabit leaves on the back of the damage leaves, young leaves after the emergence of small spots, leaves chlorosis, the occurrence of a large number of times, the entire yellow leaves, causing leaves.
The morphological features of female adult carcass were 0.52 mm in length and 0.31 mm in width. Wide oval, red. The shape of the sensilla of the caudal limb is 1.5 times as long as the width of the caudal limb; the sensillum is twig-like and shorter than the sensillum. The end of the valve groove is "U" shaped. The back half skin pattern constitutes a rhombus pattern with 13 pairs of slender back hairs, which are longer than the row spacing. The male body was 0.34 mm long and 0.16 mm wide. The length of the sensilla in the crotch is about 2 times the width; the sensilla and the sensilla are nearly equal in length. Stab hair slightly longer than the end sensilla. The end of the penis is bent toward the back to form a big-end hammer. The proximal protrusion is blunt, the distal protrusion is sharp, and the proximal edge of the back edge is slightly angled.
Living habits are about 10 generations old in the North, Taiwan is 21 generations old, and it is wintering in gaps or weeds with female adults. The flowering begins in late May, summer is a flourishing period, the proliferation rate is rapid, and it inhabits on the leaves of leguminous plants, weeds, and tea trees in winter. The average number of days in the whole year is 4l days, and the optimum temperature for development is 17— 18°C, 5-10 days of egg period, about 5-10 days from development of pups to pupae. Low rainfall and dry weather are prone to happen. The natural enemies, including the six-spotted puma, blunt cockroaches, ladybirds, Chinese grasshoppers, and florets, have a certain degree of control over the population of leafhoppers.
Prevention and control methods should adopt the principle of "prevention-based, prevention-prevention, and treatment-based combination; selection-based treatment, point-to-face combination". (1) After the harvest, remove the broken leaves and leaves, concentrate burned or buried deeply, and plow till. (2) Pay attention to the monitoring of insect pests, and find that when a small amount of leaves are damaged, the insect leaves are burned in a timely manner. In case of high temperature or drought, timely irrigation, application of phosphorus and potassium fertilizers, and promotion of plant growth inhibit the proliferation of pests. (3) Prevention of this insect should pay attention to reducing the amount of chemical pesticides to prevent the natural enemies of killing leafhoppers. The conditions of the release of predators, grasshoppers and other natural enemies, attention should be paid to the choice of drug-resistant natural enemies. (4) When there are damaged plants in the field, there are 2% to 5% leaves with leafhoppers. When there are 2-3 leaves on each leaf, picking should be carried out to control the leafhoppers in the stage of spotting. The main measure. (5) When leaf borers are widespread in the field and natural enemies cannot be controlled effectively, selective acaricides with low lethal abilities of natural enemies should be used for general treatment. Such as 25% anti-clove 23 EC 500 times solution or 20% compound Liuyangmycin EC 1000 times, 20% SCENE EC 00000, 5% synergistic anti-Siwei agent 2000 times, 73% Emulsifiable concentrate 1000 times liquid, 25% chlorfenone WP 10oo, 5% Nicorsol 2000 times, 21% Emulsion 1000 times, 2.5% Uranus (bifenthrin) 2,000 times Liquid, 20% amitraz EC 800-10oO, 35% EC 1500 times, 1.8% ECDF 3000 times (Beijing Agricultural University New Technology Development Corporation), 20% Good Year Winter EC 800 times, 10% imidacloprid wettable powder 1000-1500 times, 50% Torque wettable powder 1500 times, 15% chlorinated ketone emulsion 1500 times, 50% bromodecyl ester 800-1000 times . Many new acaricides have experienced a significant decrease in sensitivity after several consecutive uses. If amitraz is used on eggplants after 6 consecutive applications, the efficacy is reduced to 58%, so care should be taken to alternate the use of drugs.
