Abstract: In a bid of scientifically scheming the tasks of controlling the intensity of Monochamus alternatus popularity, the prediction models for four adult stages, which means the onset, the incipient peak, the peaking season and the last maximum, are originally figured out under the method of stepped-regression analysis with the logs originated from the trapped Monochamus alternatus over the years of 2017-2022 and from the meteorological factors (average maximum temperature, average minimum temperature, average temperature, average precipitation and average relative air humanity) in each early-month, mid-month and late-month occured contemporarily in Chongzhou City, Sichuan,China. Then, the models are established after being checked out with the relative data in 2023. The experimental results see that prediction results with the models are significantly accurate within the permitted range of the tolerance deviations ±3 d, approximately at 96.4%.
