摘要

为了寻找一种能有效控制松毛虫的昆虫病原线虫(Monochamus alternatus Hope)(鞘翅目:天牛科)，我们在土壤样品中筛选了一种能有效控制松毛虫的昆虫病原线虫(EPN)。获得的线虫种群命名为SOz01分离株，分子鉴定为异habditis megidis Poinar, Jackson and Klein(线虫纲:异habditidae)。在实验室条件下，将侵染SOz01的幼虫接种于交替田鼠成熟幼虫上，接种20只以上，死亡率为86-100%。即使幼虫只接种了5只ij，也有三分之一的幼虫死亡。这一发现表明，megidis SOz01对交替田鼠有较强的杀虫作用。

Insecticidal effect of the entomopathogenic nematode Heterorhabditis megidis (Nematoda: Heterorhabditidae) baited from the soil on the larvae of Monochamus alternatus (Coleoptera: Cerambycidae)

To scout for an entomopathogenic nematode (EPN) that effectively controls the pine sawyer beetle, Monochamus alternatus Hope (Coleoptera: Cerambycidae), we screened EPNs from soil samples using M. alternatus larvae as bait. A population of the nematode obtained was named isolate SOz01, and molecularly identified as Heterorhabditis megidis Poinar, Jackson and Klein (Nematoda: Heterorhabditidae). In the inoculation test of the infective juveniles (IJs) of SOz01 onto mature larvae of M. alternatus under laboratory conditions, a mortality of 86–100% occurred when more than 20 IJs were inoculated. Even when the larvae were inoculated with only five IJs, one-third of them died. This finding suggests that H. megidis SOz01 has a strong insecticidal effect on M. alternatus.
