Predicting the Impact of Temperature Change on the Future …

WebSince insect development is temperature dependent, monitoring degree-day accumulation is a valuable tool for predicting pest activity. Although degree-days are simple to calculate, monitoring degree-days on a daily basis can be cumbersome. Plants also bloom earlier during warm than cool years. WebInsects are cold-blooded, so that the rate at which they develop is mostly dependent on the temperature of their environment. Cooler temperatures result in slowed growth; higher temperatures speed up the growth process. If a season is hot, more generations may occur than during a cool season.
