摘　　要：为探讨异色瓢虫对草地贪夜蛾和甜菜夜蛾混发的捕食作用及其偏好性,通过试验评估了异色瓢虫成虫对草地贪夜蛾和甜菜夜蛾2龄、 3龄幼虫的捕食功能反应与捕食偏好性。结果表明:异色瓢虫对草地贪夜蛾和甜菜夜蛾的捕食功能反应均符合HollingⅡ型功能反应模型;异色瓢虫成虫对草地贪夜蛾和甜菜夜蛾2龄幼虫的最大日捕食量分别为129.87头和153.84头,对3龄幼虫的最大日捕食量分别为20.92头和24.94头。异色瓢虫成虫对草地贪夜蛾和甜菜夜蛾2龄和3龄幼虫均表现出较强的捕食作用,异色瓢虫对甜菜夜蛾的捕食偏好性明显强于草地贪夜蛾,表明异色瓢虫在甜菜夜蛾的生物防治中具有更大的潜力。To explore the predation effect of Harmonia axyridis on the coexistence of Spodoptera frugiperda and Spodoptera exigua,in this study,evaluation of the predation function response and predation preference of adults of H.axyridis to the 2 nd and 3 rd instar larvae of S.frugiperda and S.exigua were carried out.The results showed that the predation function response of H.axyridis toboth S.frugiperda and S.exigua were belong to Holling II models.The maximum daily predation of H.axyridison the 2 nd instar larvae of S.frugiperda and S.exigua were 129.87 and 153.84,respectively,and the maximum daily predation of H.axyridison the 3 rd instar larvae were 20.92 and 24.94,respectively.The H.axyridis has a good predation effect on the 2 nd and 3 rd instar larvae of S.frugiperda and S.exigua.Compared to S.frugiperda,H.axyridis prefers to prey on S.exigua.The results showed that H.axyridis had better biological control potential against S.exigua.
