柞蚕雌蛾的贮存时间对赤眼蜂繁殖的影响

Effects of Different Storage Period of Antheraea pernyi Female Moth on Reproduction of the Trichogramma

摘要:

利用不同贮存时间的柞蚕雌蛾取卵后繁殖赤眼蜂,通过对寄生率、羽化率、平均单卵蜂数、羽化出蜂率、雄蜂率等繁殖指标的调查,结果表明:贮存后的柞蚕雌蛾用于生产对赤眼蜂繁殖有影响,随着雌蛾贮存时间的增加赤眼蜂寄生率、羽化率明显下降;平均单卵蜂数、羽化出蜂率略有下降;雄蜂率略有增加,柞蚕雌蛾贮存0～5 d各繁殖指标变化不大。

Abstract:

Breeding of Trichogramma with different period of storage Antheraea pernyi female moth by getting its eggs for factitious host eggs,percentage of parasitism,emergence percentage of factitious host eggs,average number of wasps per factitious host egg,percentage of pupae to emerge as adults,percentage of drone was determined.The results indicated that storage period of Antheraea pernyi female moth had significant effect on breeding of Trichogramma.Percentage of parasitism and percentage of emergence decresed significantly as storage prolonged.Average number of wasps per factitious host egg and percentage of pupae to emerge as adults decreased slightly.Percentage of drone uncreased slightly.There were hardly any changes in every index when Antheraea pernyi female moth was stored for 0 to 5 days.
