Abstract

Occurrences of Rhopalosipnum rufiabdominalis damage in the leaves of Japanese apricots were observed in Hadong, Gyeongnam Province, a major producing area. R. rufiabdominalis occurred from early May to mid October, with the peak occurrence of damaged leaves in mid May. To find proper timing of chemical control against R. rufiabdominalis, acetamiprid WP was sprayed weekly from 3 April, before budbreak, to 8 May in 2007. The best time for control R. rufiabdominalis was on 17 April 2007, at which the leaves were still tender and developing up to 3 to 5 leaves.

매실나무에 발생하는 붉은테두리진딧물의 경제적 방제법을 확립하기 위하여 잎 피해양상을 경남 하동에서 조사하였고, 경남농업기술원내 포장에서 방제적기를 구명하기 위하여 acetamiprid WP를 2007년 4월 3일부터 시작하여 5월 8일까지 매주 살포하였다. 붉은테두리진딧물의 매실나무 잎 피해는 5월 상순부터 발생하기 시작하여 5월 중순에 가장 많았고, 그 이후 점차 낮아졌으나 10월 중순까지 지속되었다. 또한 붉은테두리진딧물의 방제적기는 2007년의 경우 4월 17일로 잎은 여전히 연약하고 3-5장의 잎이 전개되고 있는 상태였다.
