摘要
[目的]防治松墨天牛,预防松材线虫病的发生及传播。[方法]将花绒寄甲成虫释放到林班,观察花绒寄甲对松墨天牛的寄生效果。[结果]花绒寄甲主要寄生松墨天牛老龄幼虫,松墨天牛在新干县的寄生死亡率为64.6%。[结论]随着花绒寄甲在自然界的种群量不断增加,用其防治松墨天牛的效果显著。
Objective] The aim of this study was to control Monochamus alter-natus and prevent the epidemic and spread of pine wilt disease. [Method] The adults of Dastarcus helophoroides were released to the forest, in order to observe the parasitic effect of D. helophoroides on M. alternatus. [Result] D. helophoroides parasitized the 4th instar larvae of M. alternatus, and the para-sitizing death rate was 64.6% in Xingan County. [Conclusion] With the constant increase of the populations of D. helophoroides in nature, it had a signifi-cant control effect on M. alternatus.
