| 摘 要： | 用啤酒酵母、大豆、牛肉水解物为主的饲料,制成蜡壳人工卵饲养中华草蛉(Chrysopa sinica)幼虫可以完成发育,但与用米蛾卵饲养的处理比较,幼虫历期延长,茧重减轻;对蛹历期、成茧率、羽化率、性比、产卵前期均无显著影响。将饲料制成人工卵的饲养结果比用泡沫塑料吸附法显著为好。部分龄期喂人工卵的比全幼虫期喂人工卵的影响为轻,一、二龄喂米蛾卵,三龄喂人工卵的处理,虽然对蛹重仍有影响,但在幼虫发育历期和成虫获得率上与全幼虫期喂米蛾卵的差异不显著。全幼虫期或部分龄期喂人工卵和全幼虫期喂米蛾卵饲养出来的草蛉成虫用啤酒酵母干粉作成虫饲料,30天内的产卵量差异不显著。据生防室以前的试验,三龄幼虫取食的米蛾卵量占全幼虫期总取食量的76%,因此一、二龄喂米蛾卵,三龄喂人工卵既不影响草蛉的繁殖力,又可节省大量米蛾卵,在生产实践上有应用价值。

| Abstract: | The larvae of Chrysopa sinica could complete their development on an encapsulated diet of hydrolyzed protein of brewer''s yeast,soybean,and beef,although duration of larval stage was lengthened and pupal weightdecreased as compared with those reared on rice moth eggs.The duration of pupal stage,percentage of cocoons obtained,rate of emergence,sex ratio, and pre-oviposition period were,however,not affected. |
