Extension entomologists working with spotted wing drosophila, and specifically a group spearheaded by Ash Sial at the University of Georgia, have made updates to insecticide efficacy rankings against SWD. You can find the rankings here: https://swdmanagement.org/wp-content/uploads/2021/05/SWD-rankings-document-2021.pdf. Pay attention to products and mode of action class for efficacy and rotation. Not all members of a MOA perform equally well.
