AbstractCotton aphids. Aphis gossypii. from a source near Phoenix. AZ were found to have an optimal developmental temperature of 27.5 °C with a developmental time of 5 days. Fecundity was optimal at 25 °C with 2.85 mean nymphs/day. Both development and fecundity were linear. The optimal temperature for fecundity was higher than those previously reported for cotton aphids in more moderate climates.
