摘　　要：蠋蝽(Arma chinensis)可捕食多种农林害虫,是一种颇具应用前景的天敌昆虫。利用实验室饲养观察、对比分析和野外设样地调查等方法,对蠋蝽生物学特性进行了深入研究。研究结果表明:蠋蝽在哈尔滨地区1a发生2代,以成虫越冬。蠋蝽1龄若虫只吸食水分,2龄至成虫以捕食昆虫为生。捕食量随虫龄的增长而增加。成虫平均产卵量约400粒,孵化率可达90%,一般在40～50d即可完成一代。不同温度对蠋蝽的繁殖、发育影响显著,在20℃条件下若虫发育期约42.3d,而在30℃条件下仅需29d;20℃时成虫寿命为43d,而在30℃条件下仅有28.4d。Arma chinensis is an important predatory insect for control of Lepidoptera, Coleoptera and Homoptera insect-pests in agriculture and forestry, and it is as a great potential control agent of insect pests for application of biological control in future. The research emphases on the biological characteristic and rearing condition of Arma chinensis. The experimental results indicated that： Arma chinensis occurred two generations in the West Harbin area during one year , and overwintered at the adult stage. The 1st instar nymph only sucks a bit water, but the predator from the 2st instar nymph to adult stage can prey different species of insect pests, and predation number is increased with growing nymph to adult stage. The oviposiring eggs of a female adult are about 400, and egg halchability is about 90 percent. There are about 40 to 50 days for one generation from egg to adult stage.
