Whitefly, commonly known as the "white moth," belongs to the family Homoptera. Is a polyphagous pest, mainly harmful to melons, eggplants, beans and other plants. First, the characteristics of damage A large number of adult nymphs and nymphs live on the back of the leaves and suck sap, causing the leaves to wilt, retreat green, yellow, or even die. They also secrete a lot of honeydew to induce coal pollution, cover the pollution of leaves and fruits, and seriously affect photosynthesis. At the same time, whitefly can also spread tobacco leafroll virus, induce the occurrence of virus disease and aggravate it. In severe cases, the output is reduced by 1-3%, and the individual greenhouses are not harvested. Second, prevention and control measures 1. The greenhouse for agricultural control is the wintering ground for whitefly, and pests can be eliminated in greenhouses in winter. Completely remove weeds and diseased plants before nursery or planting; seal insecticides in greenhouses with pesticides; cultivate insect-free and strong seedlings to reduce overwintering whitefly; combine pruning, remove old leaves with insects and carry them out of fields to burn or deepen Buried; autumn and winter cultivation of whitefly not eating celery, rape, leeks, garlic yellow and cruciferous, liliaceae vegetables. 2. When biological control of whitefly occurs in small amounts, the citron wasp on the petiole of the plant was placed on the petiole of the plant. The wasp laid the egg in the body of the whitefly larvae and the whitefly died 9-10 days later. Artificial grasshoppers can also be released. A grasshopper can prey on more than 170 larvae of whiteflies. 3. Physical prevention and control 30-mesh insect nets are installed in greenhouse vents to prevent whitefly invasion; use whitefly to yellow tropism, set 30-35 sheets per mu, 15cm20cm yellow slats, or place homemade in sheds. The long yellow plate (coated with a layer of viscous oil) has a remarkable effect on trapping and sticking to adult worms. It is appropriate to place 30-50 pieces per acre, which is 15 cm higher than the plants, and the height is adjusted as the plants grow taller. Can treat locusts, thrips and latent leaves 4. Control of chemical agents: (1) 5% imidacloprid tablets can be used for colonization, and one plant (0.2 g) can be placed in a planting hole to effectively prevent the harm of whitefly. (2) If the amount of whitefly is large, After closing the shed in the evening, they were smoked with 10% Isopotentiator 0.5 kg/mu. (3) 10% imidacloprid wettable powder 4000-5000 times; 3% acetamiprid emulsifiable oil 3000-4000 times; 2.5% doxorubicin emulsifiable oil 1000-1500 times; 25% thiamethoxane fine water dispersed particles Agent spray control in the morning or evening.
