性诱剂对茶园斜纹夜蛾的诱捕效果试验

Experiment on Trapping Effects of Different Sex-attractants on Prodenia litura in Tea Garden

比较不同性诱剂对茶园斜纹夜蛾的诱捕效果,并研究最佳性诱剂对其防控效果,为茶园大面积防控其发生提供优质诱芯和科学依据。通过不同厂家性诱剂对成虫诱捕数量的比较,发现杭州中茶技术服务有限公司研制的性诱剂效果最好,其次是北京中捷四方生物科技有限公司和宁波纽康生物科技有限公司。通过试验得知,取自性诱试验园内的卵块不能孵出幼虫,最佳性诱剂对斜纹夜蛾的相对防效达80%以上,能有效控制斜纹夜蛾的发生,是值得推广的绿色防控技术。

An experiment was conducted to investigate the trapping effects of sex-attractants on P.litura in tea garden in order to provide high quality inductor and scientific basis for its widespread application.By comparing the quantity of male adults trapped by sex-attractants produced by different manufacturers in the garden,it was found that the sex-attractant produced by Hangzhou zhongcha technology service company limited was the best.Second was Beijing zhongjie sifang biotechnology company limited and Ningbo Newkang biotechnology company limited.The eggs obtained from the sex attractant garden could not hatch the larvae,and the relative protective effect of the best sex attractant on S.litura was over 80%.So the sex attractants could effectively control the occurrence of S.litura,which was a green prevention and control technology worth promoting.
