摘　　要：为充分保护和利用烟田捕食性天敌红彩真猎蝽，调查研究了红彩真猎蝽成虫和若虫的形态特征和生活习性等生物学特性。结果表明，红彩真猎蝽能捕食烟田烟蚜、烟青虫和斜纹夜蛾等害虫；以斜纹夜蛾低龄幼虫为猎物饲养该天敌，其在广东南雄烟区一年发生2代，每代发育历期经历卵、1～5龄若虫和成虫，以成虫越冬；该天敌在15～35℃范围内均能正常生长发育，但发育历期随着温度升高而缩短。Development of predatory bug Harpactor fuscipes was observed with Spodoptera litura as prey for protecting and using natural enemies to control tobacco pests. The result showed that there were two life stages in H. fuscipes in Nanxiong, Guangdong, including egg, five nymphal instars and adult, live through the winter as adults. The bug grow and developed well under the temperature of 15-35℃, its developmental duration shortened with increasing temperature.
