日本刀角瓢虫对烟粉虱种群的控制作用评价
Controlling Effect of Serangium japonicum on Population of Bemisia tabaci
摘要
Abstract
The predatory ability and functional response of Serangium japonicum on Bemisia tabaci (Homoptera :A leyrodidae) were evaluated in the laboratory ,and potential of the predator in controlling the pest was estimated with a semi-field cage experiment .The results showed that the adults and all-age instar larvae of S . japonicum could prey on B .tabaci of all life stages .The daily average numbers of the egg and the 1st to the 4th nymph of the pest consumed by a female adult S . japonicum were 640.8 ,514.4 ,306.0 ,136.1 and 70.4 ,respectively .The average daily consumptions of a 1st to a 4th larva of S .japonicum on B .tabaci eggs were 57.8 ,133.7 ,403.7 and 660.9 ,respectively .The functional response of female adult S .japonicum on B .tabaci eggs was determined to be Holling Ⅱ type ,while the attack rate (α) ,handling time per egg (Th) and maximum consumption per day (1/h) were calculated to be 1.0144 ,0.0007 and 1366.78 ,respectively .Six weeks after releasing one ,3 and 5 pairs of S . japonicum per eggplant in the cage ,the controlling efficacies were 55.31%,73.25% and 84.33%,respectively ,on adult pests ,and ,53.82%,83.14% and 91.79%,respectively ,on immature B . tabaci (including eggs and nymphs) ,as compared to CK (no release of the predatory insects ) .关键词
