Abstract: The paper aims to determine spatial distribution of the bark beetles in Turpan area, provide references for the population monitoring and integrated control. We identified species through field investigation and indoor section anatomy of Turpan apricot trees, 4 different ages of apricot gardens were surveyed by using aggregation index, regression analysis and gathering mean value on the data processing. The results showed that: (1) the species of apricot bark beetle in Turpan area were Scolytus seulensis, S. rugulosus, Ernoporus sp. and S. sp.. S. seulensis had the dominant population, the second was S. rugulosus, these two species could distribute in the trunk, branches, lateral branches; Ernoporus sp. occupied thinner branches and side branches, and S. sp distributed in branches and lateral branches; (2) 5 aggregation indexes test and regression analysis were conducted on data processing, the results indicated that the spatial distribution of apricot bark beetle adult was aggregated distribution, the population was the basic component, and the aggregation distribution was density dependent, namely, the aggregation density increased with the increase of population density; (3)when the population density was small, the population aggregation was caused by the interaction of biological factors and environmental factors, when the population density was large, the environment was the primary cause of population aggregation.
