摘要
花绒寄甲Dastarcus helophoroide是松材线虫媒介昆虫松墨天牛Monochamus alternatus的重要寄生性昆虫,研究花绒寄甲对松墨天牛的寄生性对采用花绒寄甲进行生物防治有指导意义。通过在松墨天牛幼虫上接种花绒寄甲幼虫、将花绒寄甲成虫释放到林班、在受害松树上挂放花绒寄甲卵块观察花绒寄甲对松墨天牛的寄生效果,结果表明花绒寄甲对松墨天牛幼虫的接种寄生率为92%,对林班中受害木内松墨天牛幼虫、蛹的寄生率为46%。
Dastarcus helophoroide was an important parasitoid on Monochamus alternatus. In the experiment, the larvae of Dastarcus helophoroide were inoculated on Monochamus alternatus larvae, the a- dults were released to the forest and the eggs masses were hung on the infested trees. The result showed the inoculation rate of Dastarcus helophoroide on Monochamus altematus larvae was 92% and its parasitization on Monochamus alternatus larva and pupa inside the trunks was 46%.
