烟粉虱 (BemisiatabaciGennadius )是热带、亚热带和温带地区主要害虫之一。烟粉虱早在 40年代在我国就已有记载 ,现广泛分布于我国的 2 2个省市。过去烟粉虱在我国为害并不严重 ,近年来在广东和北京等地已成为蔬菜和园艺作物生产的严重障碍。除直接为害外 ,烟粉虱可传播番茄和南瓜曲叶病等5种难于防治的病毒病。到目前为止 ,已报到 1 8种寄生性天敌、1 7种捕食性天敌及 1种虫生真菌。本文简要慨述烟粉虱在我国的发生为害与传毒现状 ,并结合我国的具体情况提出非化学控制烟粉虱的对策。
Bemisia tabaci Gennadius is one of the major pests in tropical, subtropical and temperate regions. Bemisia tabaci as early as the 40’s in China has been documented, are now widely distributed in China’s 22 provinces and cities. In the past, Bemisia tabaci was not a serious damage in China. In recent years, it has become a serious obstacle to the production of vegetables and horticultural crops in Guangdong and Beijing. In addition to direct harm, Bemisia tabaci can spread 5 difficult to control viral diseases such as tomato and pumpkin leaf curl. To date, 18 parasitic natural enemies, 17 predatory natural enemies and 1 species of entomogenous fungi have been reported. This article briefly described the occurrence and transmission of Bemisia tabaci in China, and proposed a non-chemical control plan for Bemisia tabaci based on our specific situation.
