초록

양배추 유묘에서 도둑나방 유충의 경제적 피해허용수준과 요방제 수준을 설정하기 위하여 도둑나방 유충 접종 밀도에 따른 양배추의 생육, 피해 및 수량을 조사하였다. 포장실험에서 파종 40일 양배추 유묘에 주당 0, 1, 4, 8, 16마리의 도둑나방 2령 유충들을 접종하고 30일 후 수량조사결과 처리 간 사이가 없었고, 양배추는 도둑나방 가해에 대하여 보상적 반응을 보였다. 반면, 유리온실 실험에서 정식 25일 양배추 유묘에 주당 0, 2, 5, 8, 12마리의 도둑나방 2령 유충들을 접종한 결과 15일 후 양배추의 평균생체중은 무처리에서 38.3g, 2마리 접종구에서 36.7g, 5마리 접종구에서 21.7g, 8마리 접종구에서 23.3g, 12마리 접종구에서 16.7g으로 도둑나방 유충의 접종수가 증가할수록 양배추의 생체중은 유의하게 줄어들었다. 도둑나방 유충 발생과 수량손실과의 관계를 구명하기 위하여 누적발생일수(cumulative insect days)와 양배추 유묘의 손실률(%)과의 관계를 회귀분석한 결과 비선형식인 logistic 모형에 잘 적용되었다. 이 식으로부터 수익한계인(gain threshold) 5%와 양배추 상품화율(91%)을 감안했을 때, 수량 감소율 14%에서 도둑나방 2령 유충의 경제적피해수준은 44 CID 이었다. 또한 요방제 밀도는 경제적 피해수준의 80%가 되는 35 CID로 추정되었다. 본 결과는 양배추 유묘시기에 도둑나방 유충을 방제하기 위한 경제적인 방제적기를 제공함으로써 본 해충의 효율적인 관리에 활용될 수 있을 것으로 판단된다.

This study was conducted to develop economic injury level (ElL) and economic threshold (ET) of Cabbage armyworm, Mamestra brassicae L. on cabbage (Brassica oleracea L. var). The changes of cabbage biomass and M. brassicae density were investigated after introduction of larval M. brassicae (2nd instar) at different densities: 0, 1, 2, 4, 8, and 16 larvae per plant at 40 d after planting for an open field experiment, and 0, 2, 5, 8 and 12 larvae per plant at 25 d after planting for a glass house experiment. In the field experiment, the yield loss of cabbage was not significantly different among treated-plots at 30 d after the larval introduction, showing an over-compensatory response of cabbage plants to M. brassicae attack. In the glasshouse experiment, however, the biomass of cabbage at 15 d after the larval introduction significantly decreased with increasing the initial introduced number of M. brassicae, resulting in 38.3, 36.7, 21.7, 23.3 and 16.7g in above treated-plots, respectively. The relationship between cumulative insect days (CID) and yield loss (%) of cabbage was well described by a nonlinear logistic equation. Using the estimated equation, ElL of M. brassicae on cabbage was estimated at 44 CID per plant based on the yield loss 14%, which take into account of an empirical gain threshold 5% and marketable rate 91% of cabbage. Also, ET was calculated at 80% of the EIL: 35 CID per plant. Until a more elaborate EIL-model is developed, the present result may be useful for M. brassicae management at early growth stage of cabbage.
