温室白粉虱繁殖快,代数多,并有世代重叠现象,既在同一时期卵、不同龄期的若虫、成虫在植株上同时存在,缠绵不断,很难彻底清除。由于北方温室和露地蔬菜生产紧密街接、相互交错,白粉虱周年发生,为此建议采用以下方法进行防治:1、杜绝虫源。(1)在大棚或温室内轮作其不喜食的芹菜、蒜黄等蔬菜,尽量不要在大棚或温室附近种植番茄、茄子、菜豆等白粉虱喜食的蔬菜。(2)育苗室与大棚或温室分开。(3)育苗室在育苗前、温室在定植前进行熏蒸。(4)在大棚或温室的通风口上用尼龙纱密封,以控制白粉虱飞入。(5)温室或大棚在定植蔬菜前,将前茬作物的残株、杂草彻底清除,拿到室外深埋或销毁,生产期间打下的枝权、枯黄老叶带出室外处理。2、黄板诱杀。白粉虱对黄色有强烈的趋性,
Greenhouse whiteflies reproduce fast, algebraic and there is a phenomenon of overlapping generations, both in the same period eggs, different age nymphs, adults on the plants exist at the same time, continuous lingering, it is difficult to completely remove. As the North Greenhouse and open-field vegetable production close to the street, staggered with each other, the annual occurrence of whitefly, for which it is recommended to use the following methods to control: 1, eliminate the source of insects. (1) Rotate celery, garlic yellow and other vegetables that they do not like in greenhouses or greenhouses, try not to grow tomatoes, eggplants, green beans and other whiteflies that eat vegetables near greenhouses or greenhouses. (2) nursery room and greenhouse or greenhouse separate. (3) nursery room before nursery, the greenhouse fumigation before planting. (4) sealed with nylon yarn in the vents of greenhouses or greenhouses to control fly-fly infestation. (5) Before planting vegetables in greenhouses or greenhouses, remove stubble and weeds from the stubble crops thoroughly before they are planted in the greenhouses or get rid of them. 2, yellow board trapping. Whiteflies have a strong tendency to yellow,
