摘要
应用赤眼蜂是我国生物防治中较普遍的一种方式。采用3种赤眼蜂品种(松毛虫赤眼蜂,暝黄赤眼蜂,广赤眼蜂)对辽宁阜新地区油松毛虫进行了对比防治试验。结果表明:在松毛虫卵的寄生和防治效果方面都以松毛虫赤眼蜂的防效最好,2015年和2016年松毛虫赤眼蜂寄生率分别为83.13%和84.26%,防效分别为88.89%和90.20%。
The application of Trichogrammais a common way in biological control in China.The ecology of Fuxin district in Liaoning Province is relatively fragile and the protection of forest resources is particularly important.Through adopting three kinds of Trichogramma species(Trichogramma trichocarp,Trichogramma chilonis,Trichogramma evanescens)to control pine caterpillars in pine forests,result shows that at the aspect of the parasitism and control for eggs of Dendrolimus tabulaeformis,Trichinellais optimal;the parasitism rate of Dendrolimus tabulaeformis is 83.13% &84.26% respectively in 2015 and 2016,and the control effects is 88.89% &90.20%respectively.
