在低温3、8、10和12℃中,贮存被丽蚜小蜂寄生的温室白粉虱黑蛹,经过15、20、25、30和35天后的结果指出:温度越高,羽化率也越高。贮存时间越长,羽化率越低。在12℃中贮存20天,羽化率为87%,与对照93%差异不显著。带叶贮存比不带叶贮存羽化率为高。贮存时,寄生蜂的发育时期(黑蛹日龄)对羽化率无明显影响;但贮存已发育3天以上(即4日龄以上)的黑蛹,在贮存期间(20天内)陆续有羽化。黑蛹贮存20天后羽化的丽蚜小蜂,其产卵量较对照减少48%,寿命也从18.9天减少为13.8天;贮存25—30天后影响更显著。初羽化的成蜂在12℃中贮存5天后,死亡率虽仅2%,但产卵量比对照减少76%。
At 3, 8, 10 and 12 ℃, the black pupae of T. vittis were parasitized at 15, 20, 25, 30 and 35 days. The higher the temperature, the higher the emergence rate . The longer the storage time, the lower the emergence rate. Stored at 12 ℃ for 20 days, the emergence rate was 87%, 93% difference with the control was not significant. Foliar storage than non-leaf storage emergence rate is high. During storage, the parasitoid developmental period (black pupae age) had no significant effect on the emergence rate; however, black pupae, which had been stored for more than 3 days (ie 4 days old and above), developed eclosion after storage (within 20 days). Black pupae 20 days after the emergence of the Aphis gossypii, its fecundity reduced by 48% compared with the control, life expectancy reduced from 18.9 days to 13.8 days; storage 25-30 days after the more significant impact. After the first emergence of adult bees stored at 12 ℃ for 5 days, the mortality rate was only 2%, but the fecundity was reduced by 76% compared with the control.
