补充营养对切割潜蝇茧蜂的生长发育与繁殖的影响

Effects of nutrition supplementary on the development,survival and reproduction of Psyttalia incisi

结果表明,切割潜蝇茧蜂对4种处理的补充营养选择性表现为:20%(体积分数)蜜水>纯蜜>番石榴汁>清水.补充不同营养后,切割潜蝇茧蜂子代繁蜂数量存在极显著差异,表明补充不同营养会对其生殖机能产生不同影响.综合考虑繁蜂量、发育历期以及体形指标,20%(体积分数)蜜水+0.01g.mL-1酵母粉是最佳的营养组合.

The results showed that 20% （ volume fraction） honey was the optimal food to feed parasitoids. The compositor of feeding selectivity was as follows： 20% （volume fraction） honey 〉 pure honey 〉 guava juice 〉 water, and nutrition supplementary had very significant effect on the offspring number of parasitoid, which suggested that nutrition supplementary had different influences on the parasitoids＇ procreation function. Considering the offspring number, duration and body size indexes, 20% （volume fraction） honey ＋ yeast powder （0.01 g · mL^-1） was the optimal nutrition treatment group.
