복숭아혹진딧물에 기생하는 목화면충좀벌의 발육기간, 머미율, 번데기 사망률, 성비를 20, 25, 30, 25℃ 인큐베이터에서 수행하였다. 실험을 위하여 피망잎이 놓인 콤팩트샤레를 사용하였다. 각각의 4개 온도에서 발육단계별로 복숭아혹진딧물을 사육하였고 기생을 유도하기 위하여 12시간 동안 목화면충좀벌에 제공하였다. 목화면충좀벌의 알에서 성충까지 발육기간은 20℃ 18.3일, 25℃ 14.7일, 30℃ 10.4일, 35℃ 9.3일 이었다. 복숭아혹진딧물에 기생한 목화면충좀벌의 머미율은 20℃와 25℃, 1령과 2령에서 가장 높았으나 30℃와 25℃에서는 3령충에서 84.4~85.0%로 가장 높았다. 목화면충좀벌의 기주섭식률은 20~35℃까지 각각 12.5%, 17.3%, 16.0%, 10.9%였다. 목화면충좀벌 암컷의 성비는 온도별로 각각 49%, 46%, 69%, 60% 였다.
Developmental period, mummification, pupal mortality, and sex ratio of Korean strain of Aphelinus varipes Försterparasitizing the green peach aphid, Myzus persicae were studied at 20, 25, 30, and 35℃ in controlled climate cabinets. The plastic container with a leaf disc of sweet pepper (Capsicum annuum L.) was used as experimental units. Green peach aphids at different developmental stages were reared in four different temperatures and presented to A. varipes for 12 hours. A female adult of A. varipes was allowed to parasitize for 12 hours in each plastic petri dish. The periods from egg to adult of A. varipes were 18.3 days, 14.7 days, 10.4days, and 9.3 days at 20℃, 25℃, 30℃, and 35℃, respectively. The pupal mortalities of A. varipes were 0%, 1.5%, 2.8%, and 10.2% at 0℃, 25℃, 30℃, and 35℃, respectively. The mummifications of A. varipes were significantly different in all developmental stages of he aphid. The mummification of A. varipes parasitizing green peach aphid was the highest at 1st and 2nd in 20℃ and 25℃, but the highest at 3rd (84.4–85.0%) in 30℃ and 35℃. The host feedings of A. varipes were 20℃ (12.5%), 25℃ (17.3%), 30℃ (16%), and 35℃(10.9%), respectively. The sex ratios of A. varipes female were 20℃ (49%), 25℃ (46%), 30℃ (69%), and 35℃ (60%), respectively.
