开发利用自然天敌资源,是发展害虫生态控制和综合防治的重要基础工作。近年来作者对安徽茶区天敌资源进行了调查研究,结果如下:(一)茶园天敌资源丰富,且对害虫有一定控制能力初步查明安徽茶园害虫天敌,多达300余种,包括多种捕食性和寄生性昆虫、蜘蛛、捕食螨和食虫鸟类,以及多种昆虫病毒、白僵菌、虫草和蚜霉等。许多天敌昆虫明显表现与害虫的发生有同步现象和制约效应。如异色瓢虫(Leisaxyridis)、大灰食蚜蝇(Syrphus corollae)等
The exploitation and utilization of resources of natural enemies is an important foundation for the development of pest ecological control and comprehensive prevention and control. In recent years, the author conducted a survey on the natural enemy resources in the tea area of Anhui Province. The results are as follows: (1) The natural enemies of tea plantations are rich in resources and have some control over the pests. The preliminary identification of natural enemies of pests in tea gardens in Anhui Province includes as many as 300 prey species, Sexual and parasitic insects, spiders, predatory mites and insectivorous birds, as well as various insect viruses, Beauveria bassiana, Cordyceps and aphids.
