One of the more frequently asked questions about soybean aphids is how fast do they reproduce and how long do they live? Now we have an answer based on research from the University of Minnesota. Temperature effects on soybean aphid reproduction and survival have not been well understood until now. Minnesota entomologists determined the optimal temperature for soybean aphid growth and reproduction on soybean under controlled conditions. They conducted their experiments at constant temperatures of 68, 77, 86, and 95°F with a photoperiod of 16:8 (light:dark) hours.
