Effects of different treatment methods of housefly pupae for the reproduction of Pachycrepoideus vindemmiae Rondani
摘要
Abstract
It is an important way to massively rear parasitoid wasps by using appropriate methods to treat the wasps' hosts and preserve them for a long duration.Pachycrepoideus vindemmiae Rondani is a pupal parasitoid of several dipteral pests, being of significance for the biological control of the pests.In this paper, housefly pupae were frozen at -20 ℃, cold storage-preserved at 6 ℃ , and CO2-asphyxiated for 1-, 3-, and 30 days, respectively, and some pupae were heat-killed and cold storage-preserved for 30 days, aimed to approach the effects of these treatment methods on the reproduction of P.vindemmiae on the pupae.The results showed that P.vindemmiae could reproduce on the pupae treated with the above-mentioned methods, and the tibia length of the offspring had less difference with that on the fresh pupae.However, the reproduction of P.vindemmiae on the pupae treated with the above-mentioned methods except frozen decreased with the increasing preserving duration of the pupae.At the prerequisite of preserving for 30 days, frozen pupae had the highest P.vindemmiae offspring reproduction, suggesting that P.vindemmiae could be massively reared when the housefly pupae were treated by frozen and cold storage-preserved.关键词
