| 摘 要： | 有性棉蚜有多次交配习性，交配时间平均为41分钟。雌蚜寿命为28．1±6．0天，产卵前期为3．0±1．2天，产卵历期为15．3±3．8天，产卵后期为9．7±3．4大，每雌产卵8．1±1．6粒，卵的产出率平均为88．4％。群体产卵的始盛、高峰和盛末期分别在羽化后3～4天、7～8天和15～16天。未经交配的雌蚜在产卵方面有明显的负效应，产出的受精卵也不能孵化。

| Abstract: | Sexual cotton aphids mate many times, the average mating time is 41 minutes, female adult longevity 1s 28.1±6.0 days,previposition period is 3.0±1.2 days,oviposition period is 15.3±3.8 days. The number of eggs deposited by per female adult is 8.1±1.6, the average oviposition percentage is 88.4%. The prepeak, peak and post-peak of group oviposition are 3-4 days, 7-8 days and 15~16 dsys after the emergence respectively. The eggs deposited by un-mating female adult are fail to hatch. |
