Dose-response relationships for susceptible D. suzukii larvae exposed to three key insecticides.
Mortality was estimated following larval exposure to malathion, spinosad, and zeta-cypermethrin (ZC). Dose-response curves and 95% confidence intervals obtained from probit model.

Adult dose-response relationships for D. suzukii strains.
Adult mortality assessed after 8 h exposure to spinosad residues for males (A) and females (B). The Watsonville field population was assessed pre (WAT) and post (WAT-S5) five generations of larval selection. Adults from the susceptible Wolfskill strain were simultaneously assayed for comparison during the pre-selection (WOLF-1) and post-selection (WOLF-2) trials. Dose-response curves and 95% confidence intervals obtained from probit models.
