我国烟粉虱主要捕食和寄生性天敌控制能力研究进展

烟粉虱Bemisia tabaci Gennadius是一种广泛分布于世界各地的多食性害虫,对我国多个省市区的农作物和观赏植物造成了严重的危害。化学杀虫剂的大量使用在杀伤天敌的同时使烟粉虱产生了不同程度的抗性,防治越来越困难;相较于化学防治,在不同地区筛选有效的天敌对烟粉虱进行生物防治是对烟粉虱进行有效控制的重要方法。我国报道的捕食性天敌共计26科109种,寄生性天敌共计2科59种。烟粉虱防治过程中由于单一的防治效果不理想,联合多个天敌资源的利用是增加对烟粉虱的生物防治效果的重要手段。本文通过对我国烟粉虱捕食性和寄生性天敌种类系统全面的整理,同时对烟粉虱优势种天敌中的单种或者多种组合利用后对烟粉虱的的控害潜能进行综述,以期为烟粉虱天敌昆虫种类的筛选和实现高效的生物防治提供科学依据。

Progress in the control of predatory and parasitic natural enemies of Bemisia tabaci in China

Bemisia tabaci Gennadius is a polyphagous pest widely distributed all over the world.It caused serious damage to crops and ornamental plants in many provinces and cities in China.The extensive use of chemical insecticides not only kills natural enemies but also causes different degrees of resistance to B.tabaci.Compared with chemical control,biological control of B.tabaci in different areas is an important method for effective control of B.tabaci.There are 109 species of predatory natural enemies in 26 families and 59 species of parasitic natural enemies in 2 families reported in China.In the process of B.tabaci control,combined use of several natural enemies is an important way to increase the biological control effect of B.tabaci.In this paper,the species of predatory and parasitic natural enemies of B.tabaci in China were systematically sorted out,and the potential of controlling natural enemies of the dominant species of B.tabaci were summarized,in order to provide scientific basis for the selection of natural enemies of B.tabaci and the realization of effective biological control.
