螟黄赤眼蜂的个体发育

螟黄赤眼蜂广泛应用于多种农林害虫的生物防治,常用米蛾卵进行规模化繁育。本文观察了螟黄赤眼蜂在米蛾卵中的个体发育过程。结果发现,在26℃±1℃的条件下,螟黄赤眼蜂从产卵到成虫的个体发育过程历时8 d,其中胚胎期26 h,幼虫期36 h,预蛹期48 h,蛹期84 h,在产卵后的192 h后成虫开始羽化。螟黄赤眼蜂卵为白色透明的棒状,随着胚胎发育时间的增加,其长径和短径逐渐变大,但两者之比逐渐减少;刚进入幼虫期的虫体长径与短径之比较大,虫体上下宽度基本相等,但体积随取食而快速增加;虫体出现梅花斑和米蛾卵卵壳颜色变黑是进入预蛹期的标志;蛹的头、胸和腹部明显分界,梅花斑消失,腹部二条黑带逐渐横贯整个腹背...

Summary:螟黄赤眼蜂广泛应用于多种农林害虫的生物防治,常用米蛾卵进行规模化繁育。本文观察了螟黄赤眼蜂在米蛾卵中的个体发育过程。结果发现,在26℃±1℃的条件下,螟黄赤眼蜂从产卵到成虫的个体发育过程历时8 d,其中胚胎期26 h,幼虫期36 h,预蛹期48 h,蛹期84 h,在产卵后的192 h后成虫开始羽化。螟黄赤眼蜂卵为白色透明的棒状,随着胚胎发育时间的增加,其长径和短径逐渐变大,但两者之比逐渐减少;刚进入幼虫期的虫体长径与短径之比较大,虫体上下宽度基本相等,但体积随取食而快速增加;虫体出现梅花斑和米蛾卵卵壳颜色变黑是进入预蛹期的标志;蛹的头、胸和腹部明显分界,梅花斑消失,腹部二条黑带逐渐横贯整个腹背面,复眼随着时间的增加逐渐加深,最后为深红色。经过192 h的发育,螟黄赤眼蜂成虫羽化,咬破米蛾卵壳而出。

Trichogramma chilonis was commonly mass reared on Corcyra cephalonica eggs and widely used as a biological control agent against many agriculture and forestry insect pests. In this study,the individual development of T. chilonis on C. cephalonica eggs was observed at the temperature of 26℃ ± 1℃. The results showed that it was taken 8 days for T. chinolis to complete the development from egg to pupa,including 26 h of embryonic development,36 h of lava,48 h of prepupa,84 h of pupa,and adults emerged on day 9. The T. chilonis eggs laid in C. cephalonica eggs
