Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) in Peaches: is it a problem?

Andreazza, FelipeBernardi, DanielBotton, MarcosNava, Dori Edson

Healthy peach fruit is not considered a preferred host for Drosophila suzukii (Matsumura); however, it becomes a more preferable host when damaged. Thus, damaged peach fruit is of importance not only in terms of economic losses, but also because it serves as a reservoir for this fly species. This work aimed to evaluate the suitability of peaches mechanically damaged or harboring the brown rot disease as hosts for D. suzukii compared to hosts for which they have a low (undamaged peach) and high (undamaged strawberry) preference. Damaged peaches were as susceptible as undamaged strawberries. Fungus infection alone did not increase the susceptibility of peaches compared to undamaged peaches. This information should be considered when an Integrated Pest Management program is defined in a scenario of different species of fruit production.(AU)
