Assessment of Possible Expansionof the Climatic Range of Italian Locust(Calliptamus italicus L.) in Russia in the 21st Centuryat Simulated Climate Changes

E. N. Popova, S. M. Semenov, and I. O. Popov

The areas of distribution, high pest damage, and mass reproduction of Italian locust are mainly limited by climatic factors. It is demonstrated that under conditions of the RCP4.5 moderate scenario of anthropogenic impact on the global climate system in Russia in the 21st century the climatic range of Italian locust will be expanded mainly northward and, to a smaller extent, eastward. The expansion of the range by the middle of the 21st century as compared with the end of the 20th century will be more significant that at the end of the 21st century versus its middle.
