摘　　要：在湛江室内和室外对锥盾菱猎蝽进行了观察研究 ,记述了其形态特征、生物学特性和捕食量。结果表明 ,锥盾菱猎蝽在湛江 1年发生 2代 ,以 5龄若虫越冬 ;平均历期第一代为 1 31 .5d ,越冬代为 2 1 0 .5d ,若虫或成虫每天可捕食 1～ 2龄马尾松毛虫幼虫 1～ 6头。Isyndus reticulatus Stl was raised both in forest and laboratory in order to study its biology characteristics. The observation results shows that Isyndus reticulatus Stl produce two generations per year in Zhanjiang area, live through the winter as 5 instars nymph. The duration of the first generation is 131.5 days, while it is 210.5 days of overwintering generation. Each nymph or adult eat 1～6 Dendrolimus punctatus larvae of 1～2 instars per day.
