摘　　要：通过室内饲养彩纹猎蝽,研究其形态和生物学特征,为利用该天敌防治害虫提供基础资料。在温度(26±1)℃,光照16L∶8D,相对湿度(65±5)%的人工环境下,使用黄粉虫饲养彩纹猎蝽,观察记录其卵、若虫和成虫的形态特征、发育历期、捕食、产卵量等生物学特性,并分析其世代历期、有效积温等。结果表明:彩纹猎蝽在实验室条件下,卵期(8.50±0.74)d,若虫共5龄。成虫产卵前期(14.80±3.71)d,每雌平均产卵量(216.80±106.04)粒,成虫平均寿命(147.35±72.36)d。在实验室条件下完成1个世代的平均历期为81.38 d,所需有效积温为2115.88日·度。该虫能够捕食草地贪夜蛾、银纹夜蛾、斜纹夜蛾、甘薯麦蛾、小菜蛾、菜青虫、土耳其扁谷盗、致倦库蚊。研究显示彩纹猎蝽在实验室环境下一年发生4代,可以捕食多种害虫,可为进一步保护和利用该天敌提供重要参考。The morphological and biological characteristics of Euagoras plagiatus were studied through the indoor rearing,which provided basic data for the study of using this natural enemy to control insect pests.Under the artificial environment of temperature being(26±1)℃,light being 16L∶8D and relative humidity being(65±5)%,Tenebrio molitor was used to feed E.plagiatus.The biological characteristics of E.plagiatus,such as the morphological characteristics of eggs,nymphs and adults,the developmental duration,predation,and fecundity were observed and recorded,and the generation duration and effective accumulated temperature were analyzed.The results showed that:under the laboratory conditions,the egg stage of E.plagiatus was(8.50±0.74)days,and there were five instars in the nymph stage.The pre-oviposition period of the adult was(14.80±3.71)days.The average number of eggs laid per female was 216.80±106.04,and the average life span of adults was(147.35±72.36)days.The average duration of one generation under the laboratory conditions was 81.38 days,and the effective accumulated temperature was 2115.88 days·degree.E.plagialus could prey on Spodoptera frugiperda,Argyrogramma agnata,Spodoptera litura,Brachmia macroscopa,Plutella xylostella,Pieris rapae,Cryptolestes turcicus,and Culex quinquefasciatus.The study showed that E.plagiatus occurred four generations a year in the laboratory environment and could prey on a variety of pests,which could provide an important reference for the further protection and utilization of this natural enemy.
