摘要
通过室内饲养观察及实地调查,明确了脊胸露尾甲年发生规律等基本生物学特性。该虫世代重叠现象明显,每代历期约33～38d,其中产卵前期平均68d,卵历期平均32d,幼虫期平均179d,蛹期平均75d。成虫产卵明显受性比的影响,雌雄性比小时,雌虫产卵量增多。
Carpophilus dimidiatus(Fabricius)is one of the most destructive insects pest in the world. The life cycle and the fundmental biology of the pest were studied in 2000～2002.The preoviposition period was 6.8 days,egg stage lasted 3.2 days,larval stage lasted 17.9 days,and pupal stage was 7.5days.The egg production increased obviously when sex ratio was small.
