西瓜田笼罩下多异瓢虫对瓜蚜的控制作用
Control Effects of Hippodamia variegata on Aphis gossypii under Cage in Watermelon Fields
摘要
Abstract
The predatory functional response and control effect of released Hippodamia variegata on watermelon aphid,Aphis gossypii in fields were investigated. Predatory functional response was fitted as Na = 0.81228N/(1 + 0.013646N). The control efficacy reached 80.43% and 98%, respectively, on 5 d and 11 d after H. variegata was released as pupa at a rate of pupa/aphid = 30/1000, and was 72.22% and 87.36%, respectively, on 7 d and 14 d after H. variegata was released as egg at a rate of egg/aphid = 20/30. The results demonstrated the optimal release rates for H. variegata pupa and egg, and pupa was superior to egg in release of H. variegata for control of the aphid.关键词
