조명나방의 생태조사 결과 1. 조명나방은 1년에 3회 발생했으며 3화기 유충이 옥수수 그루터기나 줄기 속에서 월동, 이듬해 $5\~6$월에 번데기로 되었다. 2. 난기간은 $3\~4$일, 유충기간은 $18\~30$일, 용기간은 $6\~9$일, 성충의 수명은 $7\~11$일이었다. 9. 유충은 $5\~6$회 탈피후 용이 되었고 노숙할수록 령기간이 길었다. 4. 성충의 산란기간은 $3\~7$일 이었고 산란수는 약 $600\~800$개였다. 5. 조명나방의 지역별 옥수수 피해주율은 수원이 $50\~89\%$, 춘천이 $10\~73\%$, 평창이 $7\~29\%$였다. 6. 유충기생천적 2종, 난기생천적 1종이 조사되었고 유충기생율은 $0.8\~16.4\%$, 난기생율은 $0\~62.8\%$였다.

This study was carried out to investigate the bionomics of Ostrinia furnacalis $(Gu\grave{e}n\grave{e}e)$ in the laboratory and field in 1978. The oriental corn borer had three generations a year in Korea ana the first period of moth activity was mostly from early June to early July, the second from mid July to mid August and the third from mid August to early September. It overwintered with larval stage in the corn stubbles. The egg period was 3-4 days. The larva molted 5-6 times and its period was 18-30 days. The longevity of adult was 7-11 days and deposited about 600-800 eggs. An egg parasite and two larval parasites were investigated.
