멀티콥터(드론)을 이용한 약제 살포 효과 분석을 위해 배추의 파밤나방을 대상으로 살충제의 조건별 살포 실시 후 약효·약해를 조사하였다. 고정조건은 2M, 5M 고도 조건, 풍속 2m/s 이하이며, 오전 7~8시 경 파밤나방 1~2령을 대상으로 살충제 스피네토람 액상수화제를 기준량인 16배(1,250ml/20L)와 배량 8배(2,500ml/20L) 및 반량 32배(625ml/20L)를 살포한 결과 24시간 후 파밤나방 유충 100%가 사망하였다. 배추 잎에 외관상 나타나는 약해는 없었다.

This study was done to evaluate the susceptibility, systemic effect, residual effect and control effect in each developmental stages of biotype Q of sweetpotato whitefly against insecticides, acetamiprid+spinetoram SC and dinotefuran SG. Two insecticides were showed similar activity against the eggs, and showed higher activity in acetamiprid+spinetoram SC against the nymph and adult. In systemic effect, two insecticides have a similar activity. It was showed higher activity in root zone systemic application than leaf zone systemic application. Residual effect was showed higher in acetamiprid+spinetoram SC (92%) than dinotefuran SG (44 %) at seven days after treatment. Control effect was showed all over 90 % activity at tree- and seven days after treatment. Therefore, these insecticides are expected to control the sweetpotato whitefly effectively.
