白粉虱是近年保护地蔬菜生产的一种重要害虫,菜农称为“小白虫子”。在丹东、大连、沈阳等地均有发生。它的寄主很广,主要为害保护地的黄瓜、菜豆、番茄、茄子等。白粉虱成虫吸食植物汁液,引起叶片退绿变黄、萎蔫甚至枯死。白粉虱还能分泌大量“蜜露”,引起煤污菌滋生繁殖,污染叶片和果实,影响植物呼吸和进行光合作用。 Whitefly is an important pest of vegetable production in protected areas in recent years. The vegetable growers are called “white worms.” In Dandong, Dalian, Shenyang and other places have occurred. Its host is very wide, the main damage to protected cucumbers, beans, tomatoes, eggplant and so on. Adults of the whitefly plant extract plant juice, causing the leaves to turn green yellowing, wilting or even dead. Whitefly can also secrete large amounts of “honey dew,” causing the breeding of coal-contaminated bacteria, polluting leaves and fruits, affecting plant respiration and photosynthesis.
