Technology for preventing and controlling megalurothrips usitatus by utilizing ultraviolet light filter membrane greenhouse

Abstract

The invention discloses a technology for preventing and controlling megalurothrips usitatus by utilizing an ultraviolet light filter membrane greenhouse. The technology comprises an ultraviolet light filter membrane insect control greenhouse, a building method and technical requirements. By using the characteristic that the megalurothrips usitatus is sensitive to the specific ultraviolet light wave band and the like, the special insect-control arched closed vegetable greenhouse covered with an ultraviolet light filter membrane is designed, ultraviolet light can be prevented from entering the greenhouse, visual organs of megalurothrips usitatus pests can be interfered, the flying capacity and host plant seeking capacity of the megalurothrips usitatus pests can be affected, insect pests in the whole growth period of crops can be effectively prevented and controlled, so that the effects of ensuring the fruit quality and increasing the yield are achieved, the prevention and control effect on the megalurothrips usitatus is very obvious, and a certain prevention and control effect on small insects such as flower thrips, thrips palmi, red spiders, aphids, liriomyza sativae and bemisia tabaci can also be achieved.

Description

technical field [0001] The invention relates to related technologies for green prevention and control of crop pests in the agricultural field, in particular to a technology for preventing and controlling thrips beanus in greenhouses using ultraviolet light filter membranes. Background technique [0002] At present, fruits and vegetables grown in the southern region, such as: cowpea, pepper, eggplant, bitter melon, cucumber, Hami melon, etc., have relatively serious occurrence of small insect thrips pests in the flowers. Thrips flower, Thrips palmi, Thrips yellow breast, etc. Among them, Thrips beanus sucks flowers, young shoots or tender pods through its unique file-suction mouthparts, resulting in the stop of crop growth points and irregular growth of young pods. Symptoms such as denatured spots, leaf curling, and corky head. At the same time, flower parts, buds, and tender fruits that have been infested by insects can seriously cause flower and fruit drop, which has great ...

[0002] At present, fruits and vegetables grown in the southern region, such as: cowpea, pepper, eggplant, bitter melon, cucumber, Hami melon, etc., have relatively serious occurrence of small insect thrips pests in the flowers. Thrips flower, Thrips palmi, Thrips yellow breast, etc. Among them, Thrips beanus sucks flowers, young shoots or tender pods through its unique file-suction mouthparts, resulting in the stop of crop growth points and irregular growth of young pods. Symptoms such as denatured spots, curled leaves, corky head, etc. At the same time, the flowers, buds, and tender fruits that have been infested by insects can seriously cause flower and fruit drop, which has great harm to the fruit quality and yield of crops

[0003] Because Thrips sojae has multiple generations and overlapping generations, it has the characteristics of strong concealment, small insect body, and high fecundity. Generally, it is difficult to reach the target site by using chemical agents. Greater economic loss; currently, small insect thrips pests have developed high resistance to a variety of insecticides, especially the soybean thrips in cowpea crops have developed high resistance to most types of insecticides The use of chemical control is not ideal, and it is also accompanied by a series of problems such as high pesticide residues in crops and environmental pollution
