Understanding how weather and climate influence insect populations is vital for developing predictive population models. Factors such as temperatures and rainfall patterns can exert strong influences on insect populations and their growth. These populations vary over seasonal and yearly time scales and can sometimes quickly erupt and achieve outbreak status. Therefore, predicting pest outbreaks is vital to preparing growers for potential pest problems before serious losses occur. To elucidate population patterns of a pest insect and their relation to weather and climate requires frequent population sampling over a duration of many months and years and within several areas within its range, as well as access to reliable weather records from the same area(s) of the population samples.
