Abstract

Climate change and extreme weather events have a major impact on crop production and agricultural pests. As typically adaptive organisms, insect pests respond differently to different causes of climate change. In this review, we examine the effects of increasing temperatures and atmospheric CO2 levels, as well as changes in precipitation patterns, on agricultural insect pests. As temperature is the most important environmental factor affecting insect population dynamics, global warming is expected to lead to an expansion of their geographic range, increased winter survival, increased generation numbers, increased risk of invasive insect species and insect-borne plant diseases, and changes in their interactions with host plants and natural enemies. As climate change exacerbates the pest problem, there is a great need for future pest management strategies. These include climate and pest population monitoring, modified integrated pest management strategies, and the use of modeling prediction tools presented here.
