| description | Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) also known as “spotted wing Drosophila” is a polyphagous herbivore of Asian origin with a short life cycle, and high dispersal and reproduction rates. The arrival of this invasive pest forced a reevaluation of management strategies in Northern Patagonia. The aims of this work were to quantify the inter-annual variation of population levels, explore the influence of cultivated and wild hosts, assess the dispersal of the pest, and adjust a statistical model to describing population patterns as a function of degree days and relative humidity. We selected a cherry and raspberry orchard located in Plottier, Neuquén. Transect sampling was carried out and 33 traps were placed across an área of 12.5 km2 between 2018 and 2023. D. suzukii used fruit crops such as peach, vineyard, and plum trees as alternate hosts. D. suzukii exhibited seasonal behavior, with higher captures observed during summer and autumn. The adjusted GAMM model showed an increase in captures at 1,500 degree days (DD) and population peaks between 3,000 and 3,200 DD. This model is the first to be used in Argentina with trap capture count. Unlike conventional models, it allows for the integration of nonlinear variables. |

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) es un herbívoro polífago de origen asiático con un corto ciclo de vida, alta tasa de dispersión y reproducción. El arribo de la plaga a la Patagonia Norte replanteó las estrategias de manejo sanitario. Los objetivos del trabajo fueron cuantificar la variación inter-anual de los niveles poblacionales, explorar el rol de los hospederos alternativos, conocer la dispersión de la plaga y ajustar un modelo estadístico para describir patrones poblacionales en función de los grados días y la humedad relativa. Se seleccionó un huerto frutal de frutas finas localizado en Plottier, Neuquén. Se realizó un muestreo en transectas y se colocaron 33 trampas en una superficie de 12,5 km2 durante 2018 y 2023. D. suzukii presentó un comportamiento estacional, observándonse mayores capturas durante el verano y otoño. La mosca utilizó como hospederos alternativos los cultivos frutales como duraznero, vid y ciruelos. El modelo GAMM ajustado describió un incremento en las capturas a los 1500 GD y picos poblacionales entre los 3000 y 3200 GD. Este modelo, es el primero en utilizarse en Argentina, con datos de conteo de trampas de captura, que a diferencia de los modelos convencionales, permite relacionar variables no lineales.
