Let's do a brief review what the best way to manage this will be: One should take a two pronged approach. In some of the first literature written in Japan in 1939 (Kanzawa, T.) about spotted wing drosophila, Drosophila suzukii, (SWD), experiments were made regarding the sensitivity of the egg and larval stages of spotted wing drosophila to periods of temperatures above and below freezing (32 o F).

The antennae are short and stubby with branched arista. Spotted wing drosophila can also be managed easier in a retractable roof since the excellent ventilation through the roof allows the walls to remain closed helping to prevent the pest entry. It’s a gross sight: a little white maggot writhing on an otherwise-pristine strawberry. Spotless males are also possible, but are rarely observed in the field and should be verified by an expert for positive identification. While spotted wing drosophila is a primary pest of strawberries and other soft skinned fruits, meaning it attacks otherwise undamaged fruit, many species of native, non-pest Drosophila may feed on fruit that has been previously damaged.
