Soybean borer is a major pest of soybean. Tieling general pest feeding rate of about 20%, 30-40% of the serious year, so that reduced soybean yield, quality deterioration. In the past few years, guided by the great strategic principle of “preparing for war, preparing for war and for the people,” Chairman Mao has implemented the combination of leadership, poor and middle peasants, and technicians. The professional research departments are integrated with mass scientific experiments and established within the region The forecast network and prevention and control of research collaboration network, find out the basic rules of the growth and decline of soybean borer, to find an effective prevention and treatment methods.
