This study demonstrates the methodology and benefits of climate-driven modelling tools using the European corn borer (ECB) and Colorado potato beetle (CPB). CLIMEX models of the potential geographical distributions of each species were used to study the effects of climate change on ECB and CPB by estimating changes in population dynamics and/or infestation pressure during the first half of the 21st century. Simulations were conducted using 3 global circulation models and scaled by low and high values of global temperature change. The results predict an increase in newly established areas and in the number of pest generations per year. The ratio of arable land affected by a particular number of generations is also expected to increase. Another significant result is shown for higher altitudes currently unoccupied by pests. We recorded rapid generation increase (from 0 to 2), which supports the hypothesis that these areas are more affected by increased temperatures.
