    Relationship between aphid density during flowering season and soybean yield was surveyed in 1998-1990. Based on the 3-year study, we proposed the control thresholds of soybean aphids for different levels of soybean yield.Originating text in Chinese.Citation: Lin, Cunluan, Xun, Zhenshan, Li, Lingtang, Wang, Yanpeng, Zhang, Guangxin.

    During the growing period of soybeans, aphids are harmful to several economic parameters of soybean. The aphid population density has a significant positive correlation with the rate of soybean shriveling and significant negative correlation with the 100-kernel weight and individual kernel weight of soybean.Originating text in Chinese.Citation: Lin, Cunluan, Li, Lingtang, Wang, Yanpeng, Xun, Zhenshan, Zhang, Guangxin, Li, Suzhen.
