TL;DR: Spotted wing drosophila, Drosophila suzukii Matsumura, a native of eastern and southeastern Asia, is a pest of small and stone fruits and a potential economic threat to a host of soft- and thin-skinned fruit crops.

TL;DR: As D. suzukii continues to expand its range, steps must be initiated in each new region to educate and inform the public as well as formulate management tactics suitable for the crops and growing conditions in each.

TL;DR: From both field and laboratory studies, there was no evidence of susceptibility during the estimated ripe period, and laboratory choice tests identified that several fall-ripening alternative hosts were more susceptible than ‘Pinot noir’ or ‘ Pinot gris’ wine grapes.

TL;DR: Although fly catches among traps varied per site, overall, the Haviland trap caught the most D. suzukii, followed by the red, Van Steenwyk, and clear trap, and future trap improvements should incorporate more entry points and focus on selective baits to improve efficiency and selectivity.

TL;DR: It is suggested that wild ‘Himalaya’ blackberry (HB) Rubus armeniacus Focke or other non‐crop plants as refugia and possibly exploit adjacent field margins before colonizing cultivated fruiting crops may contribute to elevated D. suzukii populations and pest pressure.
