摘　　要：黄带犀猎蝽Sycanus croceovittatus可捕食多种害虫,是农林业害虫生物防治的重要天敌昆虫。为评价黄粉虫Tenebrio molitor、果蝇Drosophila sp.、斜纹夜蛾Spodoptera litura和棉蚜Aphis gossypii 4种猎物作为规模化饲养黄带犀猎蝽的食物来源的效果,在室内温度(25±1)℃,相对湿度(60±5)%,光周期L∥D=14 h∥10 h条件下,测定了分别取食上述4种猎物的黄带犀猎蝽生长发育和繁殖的相关生物学参数。结果表明,黄带犀猎蝽以这4种猎物为食均可完成1个世代,且可以继续繁殖,但猎物种类对其相关生物学参数有显著影响。取食斜纹夜蛾的黄带犀猎蝽成虫获得率(69.9±7.6)%,若虫总历期(70.3±0.6)d,产卵前期(21.5±0.5)d,卵期(20.0±0.1)d,单雌产卵量(213.4±22.7)粒,卵孵化率(76.5±3.6)%。其若虫死亡率较低,成虫获得率较高,若虫发育历期最短,各发育阶段的黄带犀猎蝽体重最重。与黄粉虫组相比,其成虫产卵前期显著缩短,卵孵化率显著提高,但成虫寿命较短。说明斜纹夜蛾幼虫可作为室内扩繁黄带犀猎蝽的猎物。Sycanus croceovittatus is an important natural enemy insect in the biological control of agricultural and forest pests.It could prey on a variety of prey species.In order to screen practically available prey species as food sources for mass rearing of S.croceovittatus,we evaluated the growth,development and reproduction of S.croceovittatus feeding Tenebrio molitor,Drosophila sp.,Spodoptera litura or Aphis gossypii in the laboratory under the conditions of(25±1)℃,(60±5)%RH with a photoperiod of L∥D=14 h∥10 h.The results showed that S.croceovittatus could complete development and reproduce when it feeding on these four prey species.Nevertheless,there were significant differences in its biological parameters when feeding the different prey species.The adult acquisition rate of S.croceovittatus fed with S.litura was(69.9±7.6)%;the nymphal duration was(70.3±0.6)d;the pre-oviposition duration was(21.5±0.5)d;the egg duration was(20.0±0.1)d;the fecundity per female was(213.4±22.7)eggs,and the egg hatching rate was(76.5±3.6)%.The lower mortality rates of nymphs,the shortest nymphal duration,the highest acquisition rate of adults and the heaviest body weight were observed in S.litura group.And compared with T.molitor group,the pre-oviposition duration of adults were shorter,the egg hatching rate of S.croceovittatus were higher,but the longevity of adults was shorter.In conclusion,the larvae of S.litura can be used as prey for mass rearing of S.croceovittatus in the laboratory.
