복숭아혹진딧물의 생활사를 야외에서 조사한 결과 1. 월동란은 3월하순-4월 상순에 부화하며, 부화율은 였다. 2. 5월상, 중순에 겨울숙주로 이동하여 11월 상, 중순 사이에 월동란을 낳았다. 3. 1년간 빠른 개체군은 23세대, 늦은 개체군은 9세대를 영위하였다. 4. 성숙기간은 약 10.8일, 생식기간은 약 15.8일, 수명은 28.5일이었으며 모두 봄, 가을에는 그 기간이고 여름에는 짧은 경향을 나타내었다. 5. 암컷 한 마리당 총산자수는 약 50마리, 최다산자수는 118마리 이었으며, 1일 평균산자수는 3.2마리 이었으며 1일 최다산자수는 13마리었다.

The green peach aphid Myzus persicae(Sulzer), is known as the most important vector of potato leaf-roll virus and PVY. Yield of potato plants infested with these viruses are remarkably lower than non-infested plants. A study was conducted to investigate the life history of the green peach aphid at Suweon, Korea (Lat. 'N., Long. 'E). The following were obtained: 1. Overwintering eggs hatched from late March to early April, with a hatching rate averaging ninety-five percent. 2. The fundatrigeniae leave the primary host(Punus persica) in early to mid May and migrate to the secondary hosts. 3. From mid to late Oct., the gymnoparae migrate from the secondary hosts to the primary hosts. 4. From early to mid Nov., gymnoparae lay fertilized eggs around buds, in bark crevices, or between bifurcated twigs of the primary hosts. 5. The early-born progeny have 23 generations and the late-born progeny have 9 generations on peach trees, potatoes and raddish from Apr. to Oct. 6. The average length of life was about 28.5 days, with a developmental period of approximate 10.8 days and a reproductive period of 15.8 days. 7. The average number of nymphs produced by a female was fifty, with a maximum number of 118. 8. The average number of nymphs produced by a female per day was about 3.2, with a maximum number of 13.
