Methyl bromide (MB) chamber fumigations were evaluated for postharvest control of spotted wing drosophila (SWD), Drosophila suzukii, in strawberry exports from California USA. Strawberries were infested with the most MB-tolerant age of SWD (60- to 108-h old at fumigation, ca. mature larvae), infested fruit were buried amongst uninfested fruit in export packaging, and fumigations were with 48 mg $L^{-1}$ (3.0 lbs/1000 $ft^3$) for 3 h at $18.0{pm}0.5^{circ}C$ ($ar{chi}{pm}s$). Complete mortality of $105,173{pm}3,321$ ($n{pm}s$) SWD specimens was achieved with applied dos ${geq}34.5;mg;L^{-1}$ and exposures, expressed as a concentration${ imes}$time products (CTs), ${geq}80.3;mg;L^{-1};h$.
