Actual for the Rostov area (Southern Russia) questions of distribution, biology and nocuity of two species of Acrididae: Italian locust Calliptamus italicus and Asian flying locust Locusta migratoria migratoria are considered. In the Rostov area within last decade significant increase of number of these species and expansion of the areas of settling and nocuity is marked. Increase number of Calliptamus italicus in conditions of the Rostov area has occured because of infringement of structure of crop rotations and the long termination of economic activities on the significant areas. Increase of number and expansion of the areas borrowed by gregarious form Locusta migratoria migratoria is connected with drainage of fish-breeding ponds and deducing from crop rotations of rice checks
