Abstract:

In order to compare the sensitivity of four anthranilic diamide insecticides against different phase of Spodoptera frugiperda, egg-dip, leaf-dip and poison nutrient solution-feeding methods were used to test the toxicity of chlorantraniliprole, flubendiamide, tetrachlorantraniliprole and cyantraniliprole on eggs, 3rd-larvae and adults. The results indicated that there were no ovicidal activities in the four anthranilic diamide insecticides, but could significantly reduce the survival rates of neonate larvae. The sensitivity of tetrachlorantraniliprole to 3rd instar larvae was the highest, the LC50 was 0.12 mg/L, followed by chlorantraniliprole, flubendiamide, which were 33.83, 5.21, 2.24 times of the toxicity of cyantraniliprole, respectively. The most sensitive to adults was chlorantraniliprole, which was 6.20 mg/L, followed by tetrachlorantraniliprole and cyantraniliprole, and the least sensitive was flubendiamide, which was 25.96 mg/L. The sensitivity of S. frugiperda in different phase to four anthranilic diamide insecticides had been tested by using three methods, which would provide basic data for the chemical control and resistance management of S. frugiperda.
