본 연구에서는 세 가지 온도(20, 25, 30℃)에서 꼬마남생이무당벌레의 생물적 특성을 조사하였다. 복숭아혹진딧물 약충을 먹이로 사육한 꼬마남생이무당벌레 암컷의 성충기간은 20, 25, 30℃에서 각각 134.0, 101.0, 55.2일이었고, 총 산란수는 각각 508.6, 875.6, 383.4개였고, 수 컷의 성충기간은 각각 128.8, 97.8 및 46.5일이었다. 25℃에서 꼬마남생이무당벌레의 1령, 2령, 3령, 4령, 수컷 및 암컷의 복숭아혹진딧물 성충 의 일일 평균포식량은 각각 2.2, 7.3, 14.5, 29.1, 35.0 및 42.9마리이었고, 목화진딧물 성충의 일일 평균포식량은 각각 2.2, 7.5, 13.9, 29.5, 37.0 및 40.8마리이었다.

This study was conducted to investigate the developmental characteristics of Propylea japonica Thunberg (Coleoptera: Coccinellidae) and its consumption of Myzus persicae nymphs at 3 constant temperatures (20.0, 25.0 and 30.0℃; 60 ± 5% relative humidity; 14 h light : 10 h dark). The longevity of adult female P. japonica under 20, 25, and 30℃ was 134.0, 101.0 and 55.2 days, respectively. The total fecundity was 508.6, 875.6, and 383.4 eggs during its life span, respectively. The longevity of adult male P. japonica under 20, 25, and 30℃ was 128.8, 97.8, and 46.5 days, respectively. Average daily consumption of adult M. persicae by 1st, 2nd, 3rd, and 4th instar P. japonica at 25℃ was 2.2, 7.3, 14.5, and 29.1, respectively. The average daily number of M. persicae consumed by male and female P. japonica over their lifetimes was 35.0 and 42.9, respectively. Average daily consumption of adult Aphis gossypii by 1st-4th instar P. japonica at 25℃ was 2.2, 7.5, 13.9, and 29.5, respectively. The average daily number of A. gossypii consumed by male and female P. japonica over their lifetimes was 37.0 and 40.8, respectively.
