摘　　要：为摸清茶园主要捕食性天敌的发生数量和活动趋势,给茶园害虫综合防治提供参考。本试验以信阳地区茶园主要捕食性天敌发生动态为主,采用普通型黄板和天敌友好型黄板进行监测,调查时间为3至11月,共35次,采集黄板数量为2100张。结果显示,瓢虫有3个发生高峰期,分别为3月中旬至4月下旬、6月中旬至7月下旬、9月下旬至10月下旬。两种黄板上有重叠发生的高峰期,随地理位置变化,高峰期稍有提前或推后。草蛉有三个高峰期,分别为3月中下旬,6月下旬,10月中旬至11月上旬,11月后数量逐渐减少。茶园蜘蛛有4次发生高峰期,分别是4月中下旬,5月中下旬,6月上中旬,9月中旬至10月中旬,11月以后数量减少。两种黄板以天敌友好型对天敌的保护效果优于普通型,诱集天敌数量普遍低于普通型。通过监测茶园捕食性天敌的发生动态,为制定茶园天敌利用策略提供基础数据。In order to find out the occurrence quantity and activity trend of main predatory natural enemies and provide reference for integrated pest control in tea plantation.In this study,the occurrence dynamics of main predatory natural enemies in tea plantations in Xinyang were mainly monitored by using common yellow boards and natural enemy friendly yellow boards.A total of 2100 yellow boards were collected from 35 surveys during the period from March to November.The results showed that there were 3 peak periods during the growth and development of ladybug in tea plantation,which were Mid-march to late April,mid-june to late July,late September to late October.There are overlapping peak periods on the two kinds of yellow board,and the peak periods are slightly earlier or later with the change of geographical position.The chrysopa perla has 3 peak periods,which are mid-late March,late June,mid-october to early November.There were 4 peak periods of spider in tea plantation,which were in mid-late April,mid-late May,mid-june,mid-september to mid-october,and after November.The protection effect of two kinds of yellow boards with friendly natural enemies was better than that of common ones,and the number of trapping natural enemies was generally lower than that of common ones.By monitoring the occurrence dynamics of predatory natural enemies in tea plantation,the basic data were provided for making the strategy of utilizing natural enemies in tea plantation.
