摘　　要：为利用眼纹斑叩甲(Cryptalaus larvatus)对松褐天牛(Monochamus alternatus)进行生物防治,调查广西眼纹斑叩甲的分布,并研究其生物学特性。在广西7个县(区)挂设诱捕器,定期收集眼纹斑叩甲成虫;解剖被松褐天牛危害的木段,收集眼纹斑叩甲幼虫。将成虫和幼虫带回室内饲养,观察其生物学特性。结果表明,眼纹斑叩甲在广西的分布范围广,以幼虫捕食松褐天牛,2~3年发生1代,生活史长,对松褐天牛幼虫的捕食量大;眼纹斑叩甲幼虫活跃,能在松褐天牛的蛀道间转移捕食;成虫期较长,成虫产卵量大。眼纹斑叩甲是一种有效的松褐天牛捕食性天敌。In order to utilize Cryptalaus larvatus to prevent Monochamus alternatus,distribution of C.larvatus in Guangxi was investigated and biological characteristics of C.larvatus were studied.Traps were set up in seven counties of Guangxi to collect adults regularly.Larvae were collected by dissecting wood damaged by M.alterna⁃tus.Adults and larvae were brought to laboratory to observe biological characteristics.Results showed that dis⁃tribution range of C.larvatus was wide in Guangxi,which preyed on larvae of M.alternatus with larvae,and had one generation in 2-3 years with long life history.C.larvatus could catch large amount of larvae of M.alternat⁃us.Adults lived long and laid eggs with large amount.Larvae of C.larvatus were active and could move and prey among tunnels of M.alternatus.C.larvatus is an excellent predatory natural enemy of M.alternatus.
