몇 종의 주요 농작물 해충에 대한 식물추출물(cinnamon extract 5% + citronella oil 10% + citrus oil 30% + derris extract 10% + neem extract 20% + penetrating surfactant 25%)의 살란 효과를 분무법으로 검정하였다. 노린재류의 경우 알이 부화하는 과정에서 치사하는 경향을 보였다. 식물추출물(500배액) 처리시 썩덩나무노린재(Halyomorpha halys), 톱다리개미허리노린재(Riptortus clavatus), 홍비단노린재(Eurydema dominulus), 온실가루이(Trialeurodes vaprarorium), 담배가루이(Bemisia tabaci), 파밤나방(Spodoptera exigua), 검거세미밤나방(Agrotis ipsilon) 에 대한 최종 살란 효과는 100%로 높게 나타나, 향후 산업화가 가능할 것으로 생각된다.

The ovicidal effect of plant extract mixture (5%cinnamon extract + 10% citronella oil + 30% citrus oil + 10% derris extract + 20% neem extract + 25% penetrating surfactant) against several major insect pests was tested using the spraying method. In the case of stink bugs, eggs tended to die during hatching. When treated with a plant extract mixture (500-times solution), mortality for Halyomorpha halys, Riptortus clavatus, Eurydema dominulus, Trialeurodes vaprarorium, Bemisia tabaci, Spodoptera exigua, and Agrotis ipsilon reached as high as 100%. Therefore, it is believed that industrialization will be feasible in the future.
