| Abstract: | Effects of two biological insecticides,1.3% Rotenone-Fenvalerate emulsion,0.3% Azadirachtin EC at three concentrations,0.1%,0.05% and 0.033% were studied in the field.The results showed that the two insecticides at concentration of 0.1% well controlled the adults,larvae and pupae of B.longissima.Seven days after Rotenone-Fenvalerate application,the corrected mortalities(CM) of adults,larvae and pupae were 98.52%,100% and 100% respectively;After using Azadirachtin,the CMs of adults,larvae and pupae were 94.87%,94.65%,94.90%(concentration 0.1%);These two insecticides had great control effects and should be applied to control B.longissima population in the field. |
