The cotton aphid generally occurs from emergence until the end of June, and from mid-May to mid-to-late June before squaring, when it enters the peak damage period. It adapts to lower temperatures; when the temperature is above 27°C, reproduction is inhibited and the population rapidly declines. The summer aphid occurs from mid-to-late July to August, adapts to higher temperatures, and reproduces in large numbers at 27°C to 28°C; only when the daily average temperature is above 30°C does the population decline.
