Temporal and spatial distribution can influence monitoring and treatment decisions and understanding climatic variables that affect population size can help predict peak population numbers.<br><b>2.</b><b> </b><i>Drosophila</i><i> </i><i>suzukii</i><i> </i>(Matsumara, 1931) is an invasive fruit pest, and its seasonal dynamics vary across its range. In this study, we conducted a three-year trapping study in conjunction with various modeling approaches to determine the environmental variables that influence population dynamics of <i>D. suzukii</i><i> </i>across all seasons in central Kentucky.<br><b>3.</b><b> </b>Both male and female flies were active in all seasons and visited traps located both on the ground and at plant height.<br><b>4.</b><b> </b>The greatest number of flies were caught in the wooded edge habitat in all seasons, and crop habitat only had more catches than forest habitat during summer months.<br><b>5.</b><b> </b>Finally, population size was best predicted by a general additive model that included the average temperature 8 weeks prior to sampling as well as relative humidity in the two-weeks prior to sample.<br><b>6.</b><b> </b>Taken together, our results indicate that the factors influencing population dynamics of <i>D. suzukii</i><i> </i>in Kentucky differ from those at higher or lower latitudes with average with flies active through the year and different climatic variable affecting summer catch rate.<br><b>7.</b><b> </b>Our findings highlight the need to investigate these factors on an appropriate scale to develop region-specific monitoring and management recommendations.</p>
