The effectiveness of plant-based attractants was studied using large traps, which attracted relatively more snails in agricultural water drainage ditches and rice-cultivating environments, although their effectiveness in rice fields and lakes was limited. The rate began to rise after three hours of observation. Watermelon peel exhibited the highest apple snail attraction rate (13.8%), followed by potatoes (10.0%), and apple peel (8.8%). These values significantly differed from the attraction rate attributed to papaya leaves (F=3.84; P=0.0387). After 24 h, watermelon peel and apple peel indicated a higher rate of attraction (23.4% and 21.7%, respectively), which were significantly different compared with those of papaya leaves and potatoes (F=9.94; P=0.00455). Large bait traps outperformed funnel traps in capturing golden apple snails and trapped a significant number of snails measuring over 1 cm in size. Watermelon peel was the most effective attractant for a large bait trap, followed by apple peel, potatoes, and papaya leaves. On average, 110 snails were captured in the lure net. However, potatoes, apple peels, and papaya leaves caught an average of 93, 80, and 79 snails, respectively. Among the attractants, the lure effect of the snails was not significantly different. The efficiency of large bait traps in capturing snails, regardless of the plant attractant employed, followed the order: apple peel > watermelon peel and potatoes > papaya leaves > melon > Korean melon. Watermelon peel is highly recommended for farmer use, as well as apple peel and potatoes. Utilizing these snail attractants may contribute positively to developing a safe and environment-friendly integrated pest management strategy.

자운영포장에서 알팔파바구미 유충 및 성충의 조사방법에 따른 효율을 평가하기 위하여 본 실험을 수행하였다. 알팔파바구미 유충 밀도를 Shake-bucket, Shake-picking, Sweeping net 방법을 사용한 결과 조사지역 3곳에서 조사방법과 조사시기에 따라 유의하게 차이가 있었다. 포충망을 이용하여 유충밀도를 조사한 결과 4월초까지 유충을 조사할 수 없어 초기에 발생하는 유충을 조사하는데 적합하지 않았다. Shake-bucket과 Shake-picking을 이용한 조사에서 유충발생이 3월 중순부터 확인되었으며, 두 방법간에 차이는 없었다. 미끼를 넣은 Pitfall trap을 이용하여 알팔파바구미 성충 밀도를 조사한 결과 유인조건에 따라 유의하게 차이가 있었다(p<0.018). 각 처리간 성충 유인수를 조사한 결과 싹 틔운 강남콩 92마리, 강낭콩 종자 42마리, 트랩만 설치한 것에서 39마리로 싹 틔운 콩을 넣은 트랩에서 밀도유인 효과가 가장 좋았다. 자운영답에서 알팔파 바구미를 조사할 때 초기 발생하는 유충은 Shake-bucket법을 성충은 싹 틔운 강남콩을 미끼로 하는 pitfall trap을 이용하는 것이 좋다.
