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 ft3) for 3 h at 18.0 ± 0.5 °C (x¯±s). Complete mortality of 105,173 ± 3,321 (n ± s) SWD specimens was achieved with applied doses ≥ 34.5 mg L− 1 and exposures, expressed as a concentration × time products (CTs), ≥ 80.3 mg L− 1 h.
