摘要：

本文就雅脊金小蜂Theocolax elegans(Westwood,1874)的繁殖能力和对米象幼虫的搜索能力进行了研究。结果发现,温度和繁殖方式都会影响雅脊金小蜂的产卵能力,包括产卵期、单雌产卵量和子代性比;在小麦粒中,雅脊金小蜂的垂直搜索能力可达30 cm以下。

摘要：

Fecundity and host finding behavior in the stored-wheat of parasitoid Theocolax elegans(Westwood,1874)(=Choetospila elegans Westwood,1874),a predominant parasitoid for biological control of the major stored-product insect pest,rice weevil,Sitophilus oryzae(Linnaeus) were examined.Temperature and reproduction way had a significant effect on fecundity of those female wasps of parthenogenesis or amphigony,especially on the oviposition period,overall fecundity and offspring sex ratio.The present study demonstrated that T.elegans was able to find hosts located down to 30 cm vertically from the release point.
