Abstract

Among various food base baiting materials, beer and macerated cucumber were the most effective to induce slug that is a troublesome pest on leafy vegetables, especially on lettuce. However, the baits attracted only but did not kill the pest. When the baits were combined with various insecticidal organic materials, a few combinations such as beer and cigarette mixture successfully induced and killed the slug in the field test. The most effective combination of beer 50ml and a cigarette contained in a small plastic box killed 25 slugs per night. While macerated cucumber 50ml and a cigarette mixture killed only 4.3 slugs. The bait of beer and cigarette mixture revealed 68.4% control value against slug damage when treated for 3 consecutive days in a lettuce cultivation greenhouse. The bait also effectively reduced the slug damage in a lettuce nursery showing 58.3% control value. The method seemed highly useful for the control of slug in the organic farming system in which application of pesticides are strictly prohibited.

다양한 엽채류에 발생하며 특히 상추에 피해가 큰 민달팽이는 여러 가지 식품자재 중 맥주와 오이즙액에 가장 효과적으로 유인되었다. 하지만, 이들 재료는 민달팽이를 유인할 뿐 살충효과는 전혀 없었다. 민달팽이 유인재료에 살충효과를 나타내는 물질들을 첨가하였을 때 맥주와 담배가루 혼합액의 민달팽이 유인 포살효과가 가장 높았다. 맥주 50ml에 담배 1개비 가루를 혼합하여 작은 플라스틱 용기에 담고 지표면에 매몰한 결과 하룻밤 사이에 평균 25 마리의 민달팽이가 유인 포살되는 것으로 나타났다. 하지만, 민달팽이 유인효과가 높았던 오이즙액에 담배가루를 혼합한 처리구에서는 평균 4.3마리만 유살되었다. 맥주와 담배 혼합액을 민달팽이가 심하게 발생된 상추 재배하우스에 3일간 연속으로 처리한 결과 68.4%의 방제효과를 나타내었으며, 상추 육묘상에서는 58.3%의 방제효과를 보였다. 본 연구에서 개발된 트랩은 매일 작업을 해야 하는 번거로움이 있으나 민달팽이의 피해가 큰 친환경 유기농 채소 생산농가의 육묘장이나 본포장 등 제한된 면적에서는 활용가치가 높을 것으로 기대된다.
