Abstract

This study was conducted to determine the relationship of larval density of tobacco cutworm, Spodoptera litura (Fabricius) to damage in greenhouse sweet pepper. Laboratory experiments, cage experiments by artificial release and field investigation were carried out in 2008. The leaf consumption rate increased greatly with larval development. The damaged leaves had several round or oval shape holes on the surface or lost certain parts of them, and the fruit damaged had a conspicuous hole on the surface or scar marks around the calyx. In the field investigation, fruit damage was highly correlated with larval densities and reached 3.5% damage at maximum. Cage experiments showed that numbers of non-marketable fruit increased as increasing larval densities released. The larval density at two weeks before harvest had a high relationship with the percentage of damaged-fruit at harvest. Corresponding larval density caused 1, 3, 5% of damaged-fruit was 0.2, 0.5, 0.8 larvae per plant, respectively.

본 연구는 시설재배 피망에서 발생하는 담배거세미나방의 가해에 따른 피해양상을 규명하고 밀도와 피해관계를 해석에 합리적인 해충관리의 기초자료로 활용하기 위하여 수행되었다. 잎에 대한 섭식량은 유충발육 진전에 따라 크게 증가하였다. 피해를 받은 잎은 원형 또는 타원형의 구멍이 뚫리거나 부분적으로 소실되었고, 과실은 다소 큰 구멍이 과실 표면에 뚫리거나 꽃받침 주위에 지저분한 식흔들이 있었다. 2008년 자연발생 포장에서 피해과율은 최고 3.5%에 달했고, 포장내 유충밀도와 높은 상관을 보였다. 망사케이지 접종시험에서 유충 접종수준이 높을수록 비상품과율이 증가하였고 수확 2주전 담배거세미나방 유충밀도와 수확된 과질에서 피해과 비율간에는 높은 상관관계가 있었다. 피해과율 1, 3, 5%를 유발히는 담배거세미나방 2령 유충밀도는 각각 0.2. 0.5, 0.8마리/주에 달했다.
