Abstract: Pink starlings are being introduced artificially for the biological control of grasshoppers. Nest structure and migration time of pink starlings may affect the population of grasshoppers, and could be helpful to control this insect pest. In this paper, the nests number and nest utilization rate of three different structure nests, and the migration time of pink starlings population were investigated in Xinjiang Province. Results showed that nests were made of bricks can attract about 74.8% birds, while the stone nest and the natural nest can only attract about 71.9% and 66.5% birds respectively. We concluded the effect of migration time on grasshopper population density, and results showed that it prevented about 58.4% grasshoppers before adult birds migration, while the grasshopper mortality can achieve to 88.8% before young birds migration. This study provides an important theoretical basis for the grasshopper management incorporating with pink starlings in the target region.
