Abstract: Based on the monthly average precipitation and temperature data from 14 meteorological stations in suitable distribution areas of Calliptamus italicus L.during 1961-2013，the precipitation and temperature characteristics of 3 areas（Southern Xinjiang，Tianshan Mountains and Northern Xinjiang）during the past 53 years were analyzed by using of linear regressive analysis and moving average.The results showed that the average annual precipitation in Southern and Northern Xinjiang increased significantly（P<0.05），with an amplitude peak in summer in Southern Xinjiang，and in winter in Northern Xinjiang.The average annual precipitation in Tianshan Mountains was higher than that in Southern and Northern Xinjiang，but the increasing rate was insignificant.The average annual temperature presented an increasing trend at statistical significance level（P<0.01）in 3 areas，and the rising trend was most significant in winter in Southern and Northern Xinjiang，while in autumn in Tianshan Mountains.The maximum temperature increased significantly（P<0.01）with an amplitude peak in autumn in 3 areas.The minimum temperature presented an increasing trend at statistical significance level（P<0.01）in 3 areas，and the rising trend was most significant in winter in Southern and Northern Xinjiang，while in summer in Tianshan Mountains.The rising trend of the minimum was higher than that of the maximum.In the background of global climate warming，the climate in suitable distribution areas of Calliptamus italicus L.during the last 53 years became warmingwetting，which could cause changes in geographical distribution and outbreak mechanism of locust.

Key words: Precipitation, Temperature, Maximum temperature, Minimum temperature, Climate change, Calliptamus italicus L.
