Résumé anglais
The invasive spotted-wing drosophila, Drosophila suzukii, is a major pest of fruit crops worldwide. Management of D. suzukii relies heavily on chemical control in both organic and conventional systems, and there is a need to develop more sustainable management practices. We evaluated the viability of plastic mulches as a cultural practice for D. suzukii in fall-bearing raspberry and assessed the mulches’ impacts aspects of canopy microclimate relevant to D. suzukii. Black, white, and metallic plastic mulches reduced adult D. suzukii populations by 4151% and larval populations by 52-72% compared to the grower standard. None of the mulches influenced canopy temperature or relative humidity, but metallic mulches increased canopy light intensity compared to the black mulch. Radiance in the spectrum visible to D. suzukii was altered by the mulch treatments, with overall higher radiance above white and metallic mulches compared to the black mulch and control. Future studies will determine whether changes in radiance are associated with the reported reduction in D. suzukii populations. Plastic mulches are a promising cultural practice for managing D. suzukii since they can reduce adult and larval populations.
