한국에서 담배나방(Heliothis assulta Guen e) 유충은 주로 고추과실과 담배의 어린잎을 가해한다. 따라서 본 실험에서는 이 두가지 외에 피망과 관상용 고추에 대한 1영기유충의 유인효과를 비교하였다. 다른 어느 종류보다도 고추과실에 더 많은 수의 유충이 유인되었다. 고추식물에서도 꽃이나 잎에는 거의 유인되지 않고 비교적 숙성된 고추과실에 가장 많이 몰려들었다. 이와같은 경향은 생과즙이나 10%에탄올 추출물 경우에도 비슷하며 2~4영기유충에서도 같은 경향으로 나타나 담배나방유충을 유인하는 화합식이 고추과실에 존재함을 시사하였다.

The Oriental tobacco budworm, Heliothis assulta (Guenee), larvae usually feed on the hot-pepper fruits and young tobacco leaves or buds in Korea. This experiment was conducted t(} compare their attraction to their host plants including fruits of the sweet-pepper and solanum uk kwang, besides the other two mentioned above. First instar larvae were most attracted to the hot-pepper fruits. Flowers or leaves of the hot pepper plants were not attractive either. When the hot-pepper fruits were compared for attractancy, based on developmental stages, relatively mature fruits, just before ripening, were the most attractive. Their extract with or without 10% ethanol also gave similar result to 1st instar larvae or 2~4 instar larvae, suggesting a possibility that there is an attractant(s) in the hot-pepper fruits.
