摘　　要：探讨叉角厉蝽[Eocanthecona furcellata(Wolff)]对茶谷蛾(Agriophara rhombata Meyr.)幼虫的捕食行为特性,并在室内测定了不同龄期叉角厉蝽若虫对茶谷蛾幼虫的搜索和捕食效率。结果表明,叉角厉蝽若虫通过触角摆动搜索猎物,捕杀和取食工具为其喙部可伸缩的口针,对茶谷蛾幼虫的捕食作用具有龄期选择性,高龄叉角厉蝽若虫的捕食效率更高。其中,5龄叉角厉蝽若虫对3龄茶谷蛾幼虫的捕食效率最高,平均5 min左右能搜索到猎物,13 min左右能刺吸成功并开始取食,45~60 min能吸干1头幼虫;二者密度对其捕食能力具有干扰作用。The predation behavior of Eocanthecona furcellata on Agriophara rhombata larvae was studied,and the search and predation efficiency of different instars of Eocanthecona furcellata nymph on Agriophara rhombata larva was measured in the laboratory.The results showed that Eocanthecona furcellata nymphs searched for prey by swinging their antennae and used the retractable oral needle in their beak as the hunting and feeding tool.The predation effect of Eocanthecona furcellata nymphs was selective to Agriophara rhombata larvae,and the older nymphs had higher predation efficiency.Among them,the 5th instar of Eocanthecona furcellata nymphs had the highest predation efficiency on the 3rd instar of Agriophara rhombata larvae,which could search for the prey in about 5 minutes on average,successfully imbibe and start feeding in about 13 minutes,and it could suck dry one larva in 45 to 60 minutes;the density of the two species interfered with their predation ability.
