摘 要：
本文描述了厉蝽(Cantheconidea concinna Walker)若虫和成虫的识别特征及其捕食茶尺蠖和茶蚕的行为。厉蝽若虫有剌吸茶树汁液的习性;日均捕食猎物数量随龄期的增大而增多,而随猎物幼虫龄期的增大而减少;厉蝽捕食茶尺蠖随猎物密度的增大而增多,以3龄厉蝽最明显,而捕食时相互间有干扰作用,以5龄厉蝽若虫最为明显。

摘 要：
The present paper describes the discriminating characteristics of nymphae and adult of Cantheconidea concinna Walker and its behavior in capturing. Our results shows that the nymphae of Cantheconidea concinna Walker have a tendency to piercing—suck juice of tea, and points out that latter instar of the nymphae of Cantheconidea concinna Walker captures more prey per day and less prey in latter instar is captured. The nymphae of Cantheconidea concinna Walker, especially in 3th instar, can capture more larvae of Ectropis obliqua Warren in more thick density, and mutual—disturbing effect in capturing is most clear in 5th instar.
