柞蚕卵的保存方式对松毛虫赤眼蜂繁殖的影响

摘要

试验研究了柞蚕卵的不同保存方式对松毛虫赤眼蜂繁蜂的影响，为松毛虫赤眼蜂繁蜂生产中柞蚕卵合理保存提供科学依据。结果表明：应用新鲜的柞蚕雌蛾取卵粒来繁殖松毛虫赤眼蜂，其寄生率、羽化率、单卵出蜂数等各项主要繁殖指标均最高，其次是冷藏柞蚕雌蛾的保存方式，而保存干的柞蚕卵粒的方式繁殖的松毛虫赤眼蜂，各项主要繁殖指标均明显下降，保存湿的柞蚕卵粒的方式最低。因此，赤眼蜂生产上尽量保证应用新鲜的柞蚕雌蛾卵粒，此外可以采用冷藏柞蚕雌蛾的保存方式，并辅助少量的保存干柞蚕卵粒的方式。%The effects of different storage mode of A ntheraea pernyi eggs on reproduction of the Trichogramma dendrolimi were studied in order to provide the scientific basis for reasonable restoration of A ntheraea pernyi eggs in reproduction of the Trichogramma dendrolimi .The results showed that applying fresh A ntheraea per-nyi female moth to take eggs to sire Trichogramma dendrolimi could obtain the highest value of the main re-production index such as parasitic rate ,eclosion rate of monozygotic and bee number in an egg ,followed by re-frigeration A ntheraea pernyi female moth ,storage dry A ntheraea pernyi eggs siring Trichogramma dendroli-mi ,the main reproduction indexes were significantly decreased ,storage wet A ntheraea pernyi egg was the low-est .Consequently ,Trichogramma dendrolimi production as much as possible to ensure that the application of fresh A ntheraea pernyi female moth eggs ,refrigerated of A ntheraea pernyi female moth could be used to stor-age in addition ,auxiliary few storage dry A ntheraea pernyi eggs .
