Induction and Investigation of Diapause of Aphidius vulgaris Walker in Shaanxi
摘要
Abstract
[Objective] The aim was to study influence of temperature and photoperiod on diapause of Aphidius vulgaris Walker in Shaanxi to screen out the optimal combination of temperature and photoperiod.[ Method] We studied the diapause induced factors of A.vulgaris in Shaanxi and investigated the diapause of A.vulgaris in field.[ Result] The A.vulgaris in diapause larvae, winter diapause, low temperature and short photoperiod (L:D=8:16) were the main environmental factors for the induction of diapause.Low temperature with short photoperi-od could induce diapause of A.vulgaris, at 8 ℃ the diapause rate reached 47.6%.The photoperiod could not induce diapause of A.vulgaris at 25 ℃.In Shaanxi, A.vulgaris mostly mature larvae overwintered as pupae, a few individuals or pre overwintering;the field diapause rate was up to 82.2%, and the diapause period last for 4-5 months.[Conclusion] The result provides reference for the application of Aphidius vulgaris.关键词
