검거세미밤나방(Agrotis ipsilon)은 세계적으로 중요한 나비목 해충으로 유충이 토양 속에 서식하며 다양한 작물을 가해하기 때문에 생물검정에 어려움이 많다. 본 연구에서는 검거세미밤나방에 대한 간이생물검정법을 이용해 배추를 가해하는 검거세미밤나방의 시판 살충제에 대한 감수성을 검정하였다. 시험결과, 토양혼화처리제 6종, 토양관주처리제로 8종이 90% 이상의 살충활성을 보였다.

The black cutworm, Agrotis ipsilon (Hufnagel, 1766) is a cosmopolitan pest that poses an economic threat to many crops such as pepper, corn, perilla, etc. A. ipsilon can be mass reared by providing Chinese cabbage, Brassica rapa under 60~70%, 16L:8D and 25±1℃ in laboratory. This study presents the mass rearing methods and the morphological characteristics of the immature stages of A. ipsilon including descriptions of the each immature stages.

The black cutworm, Agrotis ipsilon (Hufnagel), damages various cultivated crops and is also occasionally a serious pest of turfgrass, especially on golf courses. Essential oils have potential as alternative control agents for insect pests. Sixteen essential oils (anise, camphor, cinnamon, citronella, clove, fennel, geranium, lavender, lemongrass, linseed, neem, peppermint, pine, thyme, turpentine and tea saponin) and paraffin oil were assessed in the laboratory and the green house for their efficacy against black cutworm larvae. Treatment of potted perennial ryegrass with anise, cinnamon, neem, paraffin or turpentine reduced black cutworm damage in a greenhouse trial. Neem oil (2000 ppm) reduced growth of black cutworms feeding on treated clippings within 3 and 5 days. Treatment of perennial ryegrass in pots resulted in 100, 100 and 46% mortality of black cutworm at 4000, 2000 and 1000 ppm, respectively. Weight of survivors at the 1000 ppm rate was 5 fold less than weight of comparably-aged controls.
