| 摘 要： | 利用管氏肿腿蜂及其携带球孢白僵菌进行室内防治松墨天牛幼虫试验,结果表明:管氏肿腿蜂对松墨天牛幼虫的寄生死亡率随着接蜂量的增加而提高。在一定的接蜂量(虫蜂比1∶2~1∶5)下,松墨天牛龄期越大,被寄生效果越低,对3龄幼虫的平均寄生死亡率为90%,4龄虫平均为77.5%,5龄虫平均为52.5%。每只管氏肿腿蜂携带球孢白僵菌约1×107个孢子时,对4~5龄松墨天牛幼虫按虫蜂比1∶1、1∶2和1∶3接蜂,寄生感染死亡率分别为55%、75%和100%;管氏肿腿蜂携带球孢白僵菌防治木段内的松墨天牛幼虫寄生感染死亡率为87.13%。 |

| Abstract: | The results showed that the parasitical death rate of Sxleroderma guani on Monochamus alternatus raised with the increasing of touching S.guani.Under a certain amount of touching S.guani(M.alternatus amount : S.guan amount=1∶2～5),the bigger the M.alternatus instar was,the lower the parasitized effect was,the average parastizing death rate was 90% for the 3-instar larva,77.5% for the 4-instar larva,and 52.5% for the 5-instar larva. When every S.guan carried about 1×10~7 spores of coccoid Beauveria bassiana,and touched the 4～5-instar of M.alternatus larva with 1∶1,1∶2 and 1∶3,the ratios of M.alternatus amounts to S.guan amounts,the parastizing infecting death rates were 55%,75%,and 100% respectively; S.guan carried coccoid Beauveria bassiana to control M.alternatus in the wood section,and the rate was 87.13%. |
