복숭아혹진딧물의 포식기생자인 콜레마니진디벌의 기능반응을 온도별(15, 20, 25, 30°C) 복숭아혹진딧물 밀도를 달리하여(2, 4, 8, 16, 32, 64, 128마리) 평가하였다. 모든 온도 처리에서 콜레마니진디벌은 제 3 유형의 기능반응을 보였다. 30°C에서 공격률(0.0043 day-1)은 높았지만 처 리시간(0.9268 day)은 다른 온도보다 길었다. 추정된 처리시간은 온도가 15°C에서 25°C로 증가할수록 감소하였다. 콜레마니진디벌의 24시간동 안 최대 공격률은 15, 20, 25, 30°C에서 29.1, 31.9, 59.3, 25.9이었다. 온도처리별 복숭아혹진딧물 기생률은 유사한 특징을 나타내었다. 가장 높 은 기생률은 15, 20, 25, 30°C에서 복숭아혹진딧물 32, 32, 16, 32마리에 대해 0.52, 0.54, 0.57, 0.40이었으며 25°C에서 콜레마니진디벌의 기생 력이 가장 높게 나타났다. 본 연구는 복숭아혹진딧물의 생물적 방제원으로서 콜레마니진디벌의 효율성을 여러 온도조건에서 평가하였다.

In this study, we evaluated the functional response of Aphidius colemani Viereck (Hymenoptera: Braconidae), a parasitoid of Myzus persicae (Sulzer) (Hemiptera: Aphididae), at different temperatures (15, 20, 25, 30°C) and varying aphid densities (2, 4, 8, 16, 32, 64, 128 individuals per leaf). At all temperature treatments, A. colemani exhibited a Type III functional response. The attack rate was high at 30°C (0.0043 day-1), but the handling time (0.9268 day) was longer compared to other temperatures. The estimated handling times decreased as the temperature increased from 15°C to 25°C. The maximum attack rates of A. colemani over 24 hours were 29.1, 31.9, 59.3, and 25.9 at 15, 20, 25, and 30°C, respectively. The parasitism rates of M. persicae under different temperature treatments showed similar characteristics. The highest parasitism rates were observed at aphid densities of 32, 32, 16, and 32 individuals for 15, 20, 25, and 30°C, with values of 0.52, 0.54, 0.57, and 0.40, respectively; the parasitism efficiency of A. colemani was highest at 25°C. This study evaluates the efficiency of A. colemani as a biological control agent for M. persicae under various temperature conditions.
