六斑月瓢虫对豆蚜捕食功能反应研究

Study on the predation functional responses of Menochilus sexmaculates Fabricius to Aphis craccivora Koch

研究了六斑月瓢虫各龄幼虫和成虫对豆蚜的捕食功能反应,并进行了Ho lling-Ⅱ型和Ho lling-Ⅲ型功能反应模型拟合,结果表明,六斑月瓢虫的捕食量随虫龄的增大而增加,其发现率和最大捕食量也增大,平均处理时间减少。

The predacious effects of Menochilus sexmaculatus Fabricius to Aphis craccivora Koch at different ages were studied in this paper. The functional responses were stimulated by Holling-Ⅱ model and Holling- Ⅲ model. It showed that the number of predation increased as the age increased, its quest constant and the maximum of predation mereased too, the average handling time reduced.
