Description
Soybean aphid (Aphis glycines Matsumura) and soybean stem borer [Melanagromyza sojae (Zehntner)] are the major pest insects in the seedling stage of soybean, which cause 30% loss of soybean production in average year. The purpose of this experiment was to identify insecticides that have striking effects on aphids and with no clear injury on natural enemies. The overall target of the experiment was to protect natural enemies and apply them on keeping ecological balance in soybean field as well as to avoid eco-disastrous caused by chemical controlling happened in cotton field in North China and paddy rice field in the South.
