通过适当方法处理寄主并长期保存,是大量繁殖寄生蜂的重要途径.蝇蛹金小蜂是多种有害蝇类的蛹期重要寄生蜂,在生物防治上具有重要价值.本文探讨了蝇蛹金小蜂对-20℃冷冻、6℃冷藏和二氧化碳窒息处理1、3和30d的家蝇蛹以及热处死和热处死后冷藏保存30d家蝇蛹的寄生能力.结果表明:蝇蛹金小蜂可以利用上述蝇蛹,且其后代在胫节长度上均与源自新鲜蛹的寄生蜂胫节长度无显著差异;但除冷冻方法外,寄生蜂后代产量均随寄主保存时间的延长而降低.在保存30d的前提下,冷冻方法保存的寄主上寄生蜂后代最多.表明在大量繁殖蝇蛹金小蜂时,可以利用冷冻等方法对寄主进行处理并保存.
It is an important way to multiply the parasitic wasps when dealing with the host through proper methods and long-term preservation.Marinae is one of the important parasitoids in the pupal stage of many harmful flies and has important value in biological control.In this paper, The parasitism of pupae of housefly pupae exposed to -20 ℃, 6 ℃ and 1, 3 and 30d after chilling treatment and 30d of housefly pupae after heat-killed and heat-killed respectively showed that: There was no significant difference in the length of tibia between the flies and the parasitoid from the fresh pupae using the above pupae, but the yield of parasitoids decreased with the prolongation of the host preservation time except for the freezing method Under the premise of storing for 30 days, the frozen-preserved host had the largest number of parasitic wasps, which indicated that in the process of large-scale breeding of the pupae, the host could be treated by cryopreservation and preserved.
