摘    要:垫跗螋Chelisoches morio (Fabricius)是入侵害虫椰心叶甲Brontispa longissima (Gestro)的一种本地天敌.为了了解垫跗螋的生物学习性和控害潜能,本文对垫跗螋的形态特征、生长发育、重要生物学习性以及对椰心叶甲的捕食选择性和捕食量进行了观察研究.垫跗螋雌成虫将产的卵堆积在一起,抱孵在体下,且不时用口器翻动重排卵,受到惊扰时会吃掉卵,甚至初孵的若虫.在室温条件下(20±2)℃,以椰心叶甲2龄幼虫为食料,垫跗螋从卵至成虫的平均发育历期为(107.9±15.2)d;平均每头雌虫产卵量为(138.7±59.5)粒;垫跗螋成虫对椰心叶甲2龄幼虫的日平均捕食量为(6.7±1.1)头.寄主龄期选择性实验表明,垫跗螋成虫和4龄若虫喜欢取食椰心叶甲的2龄幼虫;3龄和2龄若虫喜欢取食椰心叶甲的1龄幼虫.

关 键 词:垫跗螋  椰心叶甲  交配  抚育  取食

Abstract:Chelisoches morio(Fabricius) is a native natural enemy of Brontispa longissima (Gestro), which is an invasive pest in China. To understand the biology and feeding capacity of C. morio, its morphology, development, breeding and feeding were observed and evaluated. The female laid her eggs together, hatching them under its body and replacing eggs with it mouth. If females are disturbed they eat their eggs and nymphs. At (20 ± 2) ℃ , development from eggs to adults took (107.9 ± 15.2) days and each female laid (138.7 ±59.5) eggs on average. Aduh C. morio consumed an average of (6. 7 ± 1.1 ) second instar B. longissima every day. Choice tests showed that adult and 4th instar C. morio prefered 2nd instar B. longissima, while 3rd and 2nd instar C. morio prefered 1st instar B. longissima.
Keywords:Chelisoches morie  Brontispa longissima  mating  breeding  feeding
