瓢虫对烟蚜的控制效能及异色瓢虫与烟蚜茧蜂的取食竞争作用
The Predation Efficiency of Lady Beetles on Myzus persicae and Feeding Competition of Harmonia axyridis with Aphidius gifuensis
摘要
Abstract
Predation efficiency of lady beetles on Myzus persicae Sulzer was tested with four lady beetle species,Coccinella septempunctata Linnaeus,Harmonia axyridis Pallas,Menochilus sexmaculata Fabricius and Propylea japonica Thunberg on M.persicae.Moreover,the feeding competition of two types of predators,H.axyridis and A.gifuensis were tested in laboratory.The four species of lady beetles could complete their whole development on M.persicae,developmental duration was ranked as H.axyridis (17.11 d),C.septempunctata (16.25 d),M.sexmaculata (13.69 d) and P.japonica (12.73 d).The duration of the fourth instars ofH.axyridis (4.15 d) was significantly longer than that of other species.The total predation on M.persicae varied significantly between the beetles,which was 687.0,635.6,359.2 and 253.2 forH.axyridis,C.septempunctata,M.sexmaculata and P.japonica,respectively.In coexistence of A.gifuensis and H.axyridis,the number of M.persicae attacked by A.gifuensis and H.axyridis decreased with increase in the number of H.axyridis.Parasitism by A.gifuensis decreased with increase of the number ofA.gifuensis,but predation by H.axyridis was not affected.The results will provide a theoretical base for rational utilization of two natural enemies for the control ofM.persicae.关键词
