There are many species of aphids in Iraq that reproduce Parthenogenesis. They appear from October to May of the following year at temperatures between 18 and 35 degrees Celsius. Recently, with the rise in temperatures by 5-8 degrees above the average, the spread of insects is observed. What explains this behavior and adaptability when this pest?
Its very interested case , the aphids adaptability with temperature
Temperature directly influences the development and behavior of aphids. In most of the year they have no wings, but in adverse weather conditions (Example: high temperatures) or lack of food, they develop wings to migrate (as indicated by @Tawfiq M. Al Antary). That factor (temperature) is always present and is the most decisive in aphid behavior. However, several studies indicate that the interaction between temperature and precipitation has a significant effect on their behavior and since both factors generally coexist in agricultural crop fields generally established in the rainy season, a study including both factors could provide closer scenarios to the realities of the field.

It is very true that temperature plays a crucial role in the development of aphids. An added temperature will produce winged ones but at the same time the predatory fauna will also be multiplied at a faster rate. In this condition, the population of aphids will decline.
Dears. Tawfiq M. Al Antary and Rakesh Pandey and For your high-value answer .
