To clarify the invasion pathways of the Dociostaurus maroccanus （Thunberg） into the Ili region of Xinjiang， China， this study used the Hybrid Single-Particle Lagrangian Integrated Trajectory Model （HYSPLIT） combined with the flight parameters of D. maroccanus and the corresponding meteorological data during its invasion to analyze the invasion trajectories of this locust under the condition of 850 hPa. The results showed that the northwest wind prevailed in Xinjiang from June to August， with an average wind speed of approximately 3 m·s^-1， which provided favorable conditions for the invasion of D. maroccanus. In the backward trajectory analysis from June to August， the probabilities of D. maroccanus invading via the route from Kazakhstan to Huocheng County were 91.66%， 100%， and 83.87%， respectively. Among these， the trajectories in June were the most consistent with the biological characteristics and occurrence patterns of D. maroccanus， further confirming that the invading population of D. maroccanus in China was originated from the Almaty Region of Kazakhstan.
