Modeling the seasonal activity and infestation risk of Drosophila suzukii (Diptera: Drosophilidae) in U-pick blueberry orchards in Indiana, USA.

ABSTRACT: Drosophila suzukii (Matsumura) is an important pest affecting small fruit crops worldwide. Given its short generation time and multiple, overlapping generations annually, population monitoring remains a critical integrated pest management strategy to detect and track population dynamics throughout the season. In this 3-year study, we leverage adult D. suzukii trap captures from Scentry monitoring traps to develop a degree-day model for this invasive fly in small (<25 acre) U-pick blueberry orchards in Indiana. Three common blueberry varieties ('Bluecrop,' 'Blueray,' and 'Elliott') were also examined to identify berry characteristics known to influence D. suzukii infestation. A two-parameter generalized logistic model explained ≥ 80% of the variance between cumulative degree days and the cu
