摘要:
为明确四川地区七星瓢虫对大豆蚜的捕食能力，在室内条件下研究了七星瓢虫成虫密度、种内干扰及温度对七星瓢虫成虫捕食能力的影响。结果表明：七星瓢虫成虫对大豆蚜的捕食功能反应符合HollingⅡ方程，回归模型为Na=1.191Nt/(1+0.005 26Nt)；七星瓢虫成虫对大豆蚜的捕食作用受自身密度制约，平均捕食量随自身密度增大而减少，拟合Watt模型为A=21.9P-1.75；七星瓢虫成虫之间存在种内干扰，干扰反应回归模型为E=0.169P-0.027 7；温度对捕食功能的影响较大，30℃时搜寻效率最高，释放天敌时应加以考虑。
Abstract:
The effects of predator density,intraspecific interference and temperature on the predation function ofCoccinella septempunctata L.were studied in the laboratory to make clear the predation ofCoccinella septempunctata L. on Aphis glycines in Sichuan.The results showed that the functional response of C.septempunctata on A.glycines was belonging to Holling-Ⅱ and the regression equation was Na=1.191Nt/(1+0.005 26Nt).The predatory function of C.septempunctata on A.glycines was affected by the density of C.septempunctata, the average amount of prey consumed decreased with the increase of prey density,the Watt equation was A=21.9P-1.75.There was intraspecies interference among adult C.septempunctata and the interference regression equation was E=0.169P-0.027 7.Temperature had great influence on predation.The maximum search rate was at 30℃.
