Abstract
[Objective] The aim was to study the biological control ways of Clostera anastomosis.[Method] Toxicity and forest control effect of 1% celangulin missible oil,0.3% celangulin missible oil,Bacillus thuringiensis(Bt) and granule virus(GV) of C.anastomosis against C.anastomosis larva were determined.[Result] The corrected mortalities of 3nd instar C.anastomosis larvae to diluted 1 000 times of 1% celangulin missible oil,1.26×107 spore/ml Bt suspension and 1.36×108 OB/ml GV suspension were 92.17%,92.53% and 91.07%,respectively.Forest control test result showed that the corrected mortalities of diluted 1 000 times of 1% celangulin missible oil and 1.26×107 spore/ml Bt suspension against C.anastomosis larva were 83.53%-86.59% and 84.05%-86.13%,and the corrected mortality of 1.52×108 OB/ml GV suspension was over 89%.[Conclusion] The research result provide reference for biological control ways of C.anastomosis populations.
