[Methods] Nine kinds of pesticides were used to control pests on soybean. A petri dish efficacy test was first performed in laboratory,then a leaf efficacy test was performed in a greenhouse,and finally,three kinds of agents with good efficacy in the two tests were selected for field control tests. [Results] The indoor and outdoor test results showed that abamectin was the best agent,which showed efficacy higher than 96%,followed by bifenthrin,whose efficacy was higher than 93%. It can be seen that abamectin is the best choice for the prevention and control of T. truncatus,and bifenthrin can also be used according to the situation. [Conclusions] This study provides a theoretical basis for the control of T. truncatus.展开更多
