柑桔介壳虫寄生蜂研究Ⅳ:印巴黄蚜小蜂个体发育研究
STUDIES OF CITRUS SCALE PARASITOID Ⅳ.STUDY OF ONTOGENESIS OF APHYTIS MELINUS(HYMENOPTERA:APHELINIDAE)
【摘要】 在25℃,印巴黄蚜小蜂的个体发育周期为15—21天,其中卵期3天,幼虫期7—10,蛹期(包括预蛹期)5—8天。羽化后的成虫寿命3—18天。幼虫的发育分三个龄期,根据颚的大小和虫体的形态可区分各龄幼虫。并且,一龄幼虫只有4对气门,二龄和三龄幼虫有8对气门。老龄幼虫停止取食、排出粪便、然后化蛹。成虫羽化后,在介壳上咬一小孔钻出。
【Abstract】 At 25℃ the period of ontogenesis of Aphytis melinus take 15-21days,the eggstage 3days,the larva 7-10days and the pupa(including the prepupal stage)5-8 days.The longevity of adult is 3-18days.The larvae suck body fluids of host and pass through three instar,each ofwhich can be distinguished by the shape and size of the mandibles and by thegeneral appnearace.The first instar larvae have four pairs of spiracles,the econdand third instar have eight pairs of spiracles.The old larvae stop feeding,excrete the meconia,and then pupate.The adultsemerge through a hole that they chew in the covering scale.
