Abstract
The field bioassay of 4 trunk injection insecticides(14% Imidacloprid+DDVP,4.5%Imidacloprid,2%Abamectin and 30%DDVP+omethoate) was conducted against Brontispa longissima.The results showed that 14%Imidacloprid+DDVP,4.5%Imidacloprid and 30% DDVP+omethoate were efficient,and 14%Imidacloprid+DDVP exhibits high efficiency.The control effect reached 95.10% 30 days after the injection at the dose of 0.7 mL/cm trunk ground diameter.
