호남지역 콩 포장에서 톱다리개미허리노린재(Riptortus clavatus)의 발생소장, 콩 피해 및 약제방제 효과
초록
호남지역 콩 포장에서 톱다리개미허리노린재의 발생소장, 콩 피해 및 약제방제 효과를 검토하였다. 톱다리개미허리노린재의 발생은 콩 파종시기 및 연차간에 차이가 있었다. 톱다리개미허리노린재의 발생최성기는 5월 하순경 파종은 8월 하순에, 6월 중순경 파종은 9월 중순 이었고, 파종기가 동일하더라도 연차간 기상조건에 따른 중 생육상의 차이로 톱다리개미허리노린재의 발생최성기 차이가 있었다. 톱다리개미허리노린재에 의한 콩 흡즙 피해 면적을이 증가하면 발아율이 현저하게 낮아졌으며, 특히, 콩 피해면적율이 이상 되면 발아율이 로 매우 낮았다. 톱다리개미허리노린재에 대한 약제방제효과는 콩 생육단계중 (착협성기)+ (립비대기)+ (립비대성기)에 3회 처리시 의 방제효과로 가장 높았다.
Seasonal Occurrence, Soybean Damage and Control Efficacy of Bean Bug, Riptortus clavatus Thunberg (Hemiptera: Alydidae) at Soybean Field in Honam Province
Abstract
This study was conducted to determine Seasonal Occurrence, soybean damage and control efficacy of bean bug, Riptortus clavatus Thunberg at soybean field in Honam province. Occurrence of R. clavatus varied at seeding times with annual difference. The peak occurrence of R. clavatus was appeared at late of August for late May seeding and middle of September for middle June seeding. There was difference in the peak occurrence of R. clavatus due to different growing stages affected by different weather conditions though soybean was seeded at same time. If the rate of soybean seed damage area by R. clavatus sucking increases, the germinating rate was greatly decreased. If the rate of soybean seed damage area is above 50 percent, in particular, the germinating rate was very low with 2 percent. Control efficacy against R. clavatus was the highest with at 3 times treatment of insecticide at (full pod stage) + (Beginning seed stage) + (full seed stage) of soybean growing stages in field.
