四、生物防治的进展和问题茶园作为特定的生态环境,既为害虫提供了取食和生存的良好条件,也有利于天敌的定居繁衍。茶园害虫种类多,天敌资源也较丰富,已有记载的茶园害虫天敌约500种。其中包括捕食性和寄生性天敌昆虫、捕食性益螨、蜘蛛和食虫益鸟、昆虫病毒、寄生性微生物等。这些天敌是茶园生态系中的重要组成成分,是茶园害虫的生态控制因素,在害虫综合治理中,利用生物防治以控制害虫种群数量,已起到积极的作用。
Fourth, the progress of biological control and problems Tea as a specific ecological environment, both for insects to provide good conditions for feeding and survival, but also conducive to the natural enemies of settlement. Many types of tea plantations pests, natural enemies are also rich in resources, there have been recorded about 500 natural enemies of tea plant pests. These include predatory and parasitic natural enemy insects, predatory beneficial mites, spiders and insectivorous birds, insect viruses, parasitic microorganisms and the like. These natural enemies are important components in the tea plantation ecosystem and are ecological control factors for tea plantation pests. In the comprehensive management of pests, biological control has been used to control the number of pest populations and has played an active role.
