Global warming and the danger of killer caterpillars

Lee Dyer a researcher at Tulane University in New Orleans, Louisiana, warn that with global warming, parasitism against caterpillars will decrease. This in turn will free the caterpillars to devour agricultural fields and forests. Dyer and his team point out that parasitism decreases as climate variability increases. The researchers are uncertain as to the exact mechanisms that cause parasitism in caterpillars to decrease as climate variability increases The details of the research are given in an upcoming edition of the Proceedings of the National Academy of Sciences.
