Climate change is influencing migratory patterns and evolution in pests, threatening our food basket
Care adapting to climate change ROP PESTS and are evolving to spread to new areas to wreak more havoc. Dan Bebber from the department of biosciences at the University of Exeter, UK, reviewed the literature on impact of climate change on crop pests.He illustrates his findings through example of the Colorado potato beetle, which is originally from southwestern US, entered France in the 1950s and invaded most European and central Asian countries.By the 1990s,it reached China from Kazakhstan and moved towards Russia. It is difficult to predict the beetle’s migratory course as prediction models do not take into account the insect’s evolution and highly adaptable nature.
“Our review has highlighted how difficult it is to predict where damaging crop pests may turn up.
