摘要: 2003年至2006年对松材线虫病的主要传播媒介昆虫——松褐天牛的天敌昆虫进行了调查,在我国广东省首次发现了松褐天牛的一种重要捕食性天敌——天牛霉纹斑叩甲(Cryptalaus berus)。对天牛霉纹斑叩甲的形态特征进行了描述; 在室内条件下,观察研究了该天敌的捕食能力。结果显示,1头叩甲幼虫在130d的发育期里,累计捕食、杀死了27头松褐天牛幼虫,之后开始化蛹; 另1头叩甲幼虫在138d的发育期里,累计捕食、杀死了19头松褐天牛幼虫。叩甲幼虫可在松褐天牛坑道之间转移捕食。

Abstract: Natural enemies of Monochamus alternatus (Coleoptera: Cerambycidae), vector of pine wilt disease,were surveyed from 2003 to 2006. An important predator, Cryptalaus berus (Candeze) (Coleoptera: Elateridae), was first found in Dongguan, Guangdong Province. Morphology of the longhorned beetle was described. And predatory capcity of the beetle was observed in the laboratory one larva during its development period of 130 days killed and/or consumed 27, and another, 19 larvae of the cerambycid. And it was noticed that the predator could move from one host tunnel to another for predation.
