Migrating insects fly in the fast lane
Date:2/4/2010

ct just randomly drifting downwind. Many migratory insects are pests of agricultural crops, so the model will be useful for predicting migration events in the future.

Ms Burgin said "We combined the results from the radar measurements of moth flight with the outputs of a model of atmosphere motion to show that by hitchhiking on suitable winds, insects can travel at greater speeds than many migrating birds, which is important given the short lifespan of insects."

This study illustrates how insects successfully undertake long-distance migrations in favourable directions. Climate change is likely to significantly alter the frequency of insect migrants, including introducing some agricultural pests that are completely new to the UK. Thus, a better understanding of their migration strategies is increasingly crucial in helping to secure food supplies in the long term.
