摘要：叉角厉蝽是黑荆树林中害虫的一种重要的天敌昆虫，在福建省长泰县一年多代，饲养为不完整的３代，以第二代成虫于枯落叶下越冬，第三代若虫未完成发育。卵期平均９．０６ｄ；若虫５龄，平均历期２１．３ｄ，１龄植食，２～５龄及成虫捕食，仍观察到植食。饲养第一代成虫平均寿命２９．５ｄ。该虫捕食范围广泛，取食黑荆林中采集到的所有鳞翅目幼虫及部分虫种的蛹。
The biological characteristics of Canthconidea furcellata , an important predator in black wattle ( Acacia mearnsii ) forest,were observed through artificial rearing on caged branches in forests.Results showed that,in rearing trials,there were three uncompleted generations a year in Changtai County,Fujian Province in Southern China,with adults of the second generation overwintering.The first instar nymphs were gregarious and fed on tree sap only;2～5 instar nymphs and adults predated various caterpillars,but were rarely sap sucking. Tests also indicated that eggs laid by a female in her life circle were 88～168.The overall mean egg stage was 9.06 days;nymph stage lasted 21.3 days in overall mean ranging from 20～26 days in rearing trials.The longevity of adult bugs of the first generation varied from 6 to 72 days,with 29.5 days on average.Nymphs of the third generation all died before winter,mostly in the 2nd and 3rd instar.
