| Abstract: | The systematic studies on long - lasting effects of application of Suteling Bt biological insecticides to prevent and control were conducted in Wenjia farm of Xingcheng city in Liaoning. The results showed that: the killing effects of Suteling were not only great for larvas of DendroLimus sp. , which reached 90.3 % ~ 96.3 % , but available during pupa and insect stages. the death rate of pupa in prevention was 25 % higher than that in control trails, and featherization rate of insect and yield of eggs were curbed, which proved that Bt biological insecticides was of long - lasting effects for prevention and control Dendrolimus sp. . |
