摘要
Thermal requirements per developmental stage, offspring production, and percent survival of three isolates of the green peach aphid, Myzus persicae (Sulz.), were determined over a range of constant temperatures from 12.4°-29.4°C. Isolates were collected from Pennsylvania, Maine, and Washington State potato producing regions. Offspring produced, survival, and thermal requirements were not different for all three isolates. Offspring production increased from 12.4°-15.6°C and then decreased as temperature increased. Percent survival averaged 78.2% except at 29.4°C where only 26.7% survived to reproduce. Thermal requirements, with 4°C as the lower developmental threshold, were 25.2, 27.1, 30.9, 30.7, 20.4, 74.2, 201.6 and 135.7 degree days, respectively, for instars 1-4, prereproductive adults, reproductive adults, longevity, and generation time. Data were used as the basis for a computer forecast system to predict aphid population development in potato fields. © 1979 Springer.
