摘要: 【目的】研究取食不同靶标害虫对普通草蛉生长发育和繁殖力的影响。【方法】通过对普通草蛉饲喂棉蚜、土耳其斯坦叶螨和麦蛾卵3种食物,研究各龄期幼虫发育历期、死亡率、羽化率和单雌产卵量等指标。【结果】通过室内生物测定,普通草蛉幼虫饲喂土耳其斯坦叶螨后,只能发育至2龄末,并不能完成其整个生活史。普通草蛉幼虫饲喂棉蚜后,其幼虫发育时间和蛹期均少于饲喂麦蛾卵的处理,其中1和2龄幼虫的发育时间差异显著,其成虫羽化率、产卵前期天数、单雌产卵量和雌虫寿命等参数均较饲喂麦蛾卵的处理高,但差异不显著。【结论】饲喂不同靶标害虫对于普通草蛉各龄期幼虫发育历期、死亡率、羽化率和单雌产卵量等反映生长发育和繁殖力指标的影响显著,验证了草蛉幼虫虽能捕食某种害虫(螨),但某种单一被捕食者体内的营养物质并不能满足其正常生长发育所需要全部营养。

Abstract: 【Objective】 To research into the growth, development and adult fecundity of Chrysoper carnea (Stephens) fed with different target pests.【Method】By feeding Aphis gossypii, Tetranychus turkestani and egg of Sitotroga cerealella to larva of Chrysoper carnea to study its duration, mortality and fecundity.【Result】Through laboratory bioassay method, the larva of Chrysoper carnea fed with Tetranychus turkestani only developed to 2nd instar, and was unable to complete their life. The growth pupal period of Chrysoper carnea fed with Aphis gossypii was shorter than that of the treatment fed with egg of Sitotroga cerealella, the 1st and 2nd instar of larva on development period were significantly different, and the adult emergence rate, preoviposition period, egg-laying number and life span of female were higher than those fed with egg of Sitotroga cerealella, but there was no significant difference between them.【Conclusion】The growth period, mortality, eclosion rate and fecundity per female of Chrysoper carnea were significantly different to those fed with different target pests, which verified that although larva of Chrysoper carnea could prey on some insects (mite), but some prey's nutrition failed to satisfy its development.

Key words: Chrysoper carnea (Stephens); different target pests; growth and development; fecundity
