摘　　要：为开展红彩瑞猎蝽的人工规模化繁育,研制了一种以自然猎物血淋巴为主,烟草汁液为辅的微胶囊人工饲料,并对其性状和饲养效果进行了评价,以面包虫饲养的猎蝽作对照。结果表明,人工饲料微胶囊成品率73.17%,含水率92.35%,综合感官评定86.8分。取食微胶囊的红彩瑞猎蝽若虫发育历期均显著长于对照,若虫的存活率、体重均显著低于对照,随龄期的增长与对照差异的显著性逐渐减小;处理组成虫获得率16.7%,对照68.9%;成虫产卵前期显著长于对照,但产卵量和卵孵化率无显著差异。猎物斜纹夜蛾幼虫密度为8头/皿时,微胶囊饲养的红彩瑞猎蝽的捕食量显著低于对照,但在较低猎物密度时无显著差异。此种人工饲料能基本满足红彩瑞猎蝽的生长发育,可在一定程度上替代面包虫。For artificial mass production of Rhynocoris fuscipes,we developed a microencapsulated artificial diet with ingredients of hemolymph from natural prey and juice of tobacco leaves.We evaluated the properties of the microencapsulated artificial diet and its efficacy for rearing R.fuscipes,with R.fuscipes reared with mealworms as the control.The average yield rate of the microencapsulated artificial diet was 73.17%;the average moisture content was 92.35%,and the average comprehensive sensory evaluation score was 86.8.The developmental duration of R.fuscipes nymphs fed with microcapsules was significantly longer than that of the control,and the survival rate and body weight of R.fuscipes nymphs were significantly lower than those of the control.The difference in the nymphal body weight between the treatment and control group gradually decreased with increasing age.The harvest rate of R.fuscipes adults in the treatment group was 16.7%,while it was 68.9%in the control group.In terms of fecundity parameters,there were no significant differences in egg production and egg hatching rate between the treatment and the control,except for the pre-oviposition period that was significantly longer in the treatment than in the control.When the density of prey Spodoptera litura larvae was eight individuals per dish,the predatory capacity was significantly lower than that of the control,but the difference decreased when the prey density was lower.In conclusion,the microencapsulated artificial diet can basically maintain the growth and development of R.fuscipes and replace mealworms as food for R.fuscipes to a certain extent.
