Recently, the rate of cultivation of such as hairy vetch was increased as a way of reducing the current soil problem. However, the occurrence of insect pest such as bean bugs, Riptortus pedestris, were increased in the field of green manure crops and their injuries to hairy vetch were observed. While minimizing insecticide use for the environmental friendly agriculture, the control of the bean bug can be utilized environmental friendly agricultural materials (EFAMs) in the green manure crop fields. The control effects of some EFAMs and most of chemical insecticides to the bean bug were significantly high. As a result of direct spray of EFAM that contained sophora extract or neem extract, the control effects of six EFAMs were higher than 70% at 120 hours after treatments. Among them, three EFAMs were showed over 90% of control effects. On the other hand, most of chemical insecticides were showed 100% of control effect against the bean bug at 48 hours after treatment. As mortality effects of EFAMs were sloely observed until 120h after treatment, we must use selected EFAMs at the beginnibgs of occurrence and entrance in the field of green manure for effective control of bean bugs.
