Abstract

Pea weevil was easily observed in the flower and pod of garden pea, but not observed in soybean at various locations in Yeongnam district through 2001 to 2003. Number of pea weevil observed in pea flower was the highest at Milyang (20), followed by Yangsan (15), Sacheon (14) and Changnyong (13), and was the lowest at Pohang (3). On the other hand, number of pea weevil observed in pea pod was the highest at Tongyeong (192), followed by Changnyong (171), Sacheon (157) and Changwon (138), and was the lowest at Pohang (12) which showed simila. tendency with the result of pea flower. Number of pea weevil occurrence observed in pea pod after one and two times applications of Insecticides in pea field were different at harvest day of 30th May while were not significantly different at harvest day of 5th June. Likewise, number of pea pod damage after one and two times applications of insecticides were different at harvest day of 10th May while was not different at harvest day of 5th June. Thus, control efficacies of insecticides according to application times against pea weevil showed very high with above 95% at harvest day of 6th June while showed variable control efficacies at harvest of 30th May.

2001부터 2003년까지 영남지방에서 완두콩바구미는 완두의 꽃과 협에서 쉽게 관찰되었으나, 콩에서 관찰되지 않았다. 지역별 완두꽃에서 완두콩바구미의 발생수는 밀양에서 약 20마리로 가장 많았으며, 다음은 양산(15마리), 사천(14마리) 및 창녕(13마리) 순서였으며, 포항에서 3마리로 가장 적었다. 한편, 완두 협에서 완두콩바구미의 발생수는 통영에서 192마리로 가장 많았으며, 다음은 창녕(171마리), 사천(157마리) 및 창원(138마리)의 순서였으며, 포항에서 12마리로 가장 낮아 완두꽃에서의 결과와 같은 경향이었다. 약종별 1회 및 2회 약제살포 후 완두 협의 수확시기에 따른 완두콩바구미의 발생수는 5월 30일 수확구에서 차이가 있었으나, 6월 5일 수확구에서 차이가 없었다. 또한 약종별 1회 및 2회 약제살포 후 완두 립의 피해수는 5월 30일 수확구에서 차이가 있었으나, 6월 5일 수확구에서 차이가 없었다. 따라서 약종별 살포횟수에 따른 방제효과는 5월 30일 수확구에서 차이가 있었으나, 6월 5일 수확구에서 유의한 차이 없이 약 96% 이상의 방제가를 나타내었다.
