La mouche Drosophila suzukii provoque depuis 2011 des dégâts importants sur fraises en France.Les stratégies de lutte préconisées contre Drosophila suzukii reposent sur de la prophylaxie (éliminer les fruits attaqués ou en sur-maturité de la parcelle), de la détection précoce (pièges attractifs), de la lutte chimique non compatible avec la faune auxiliaire. Include in email: 1) Pest Alert name, 2) number of packs desired (only available in packs of 50) and, 3) the date they will be needed. A standard curve was created, relating amount of second instar D. suzukii DNA to Cq values (amount of fluorescence) generated by qPCR.

Larve. Ravageurs. Drosophila (SWD), Drosophila suzukii What does it look like when SWD lay eggs on fruit? What does damage look like 3-4 days after SWD lays egg on fruit?
Of 19 Drosophila species tested, DNA from one species in the invaded range of D. suzukii was amplified, but it was distinguishable from D. suzukii due to different amplicon melting temperatures. Por lo tanto, se define lo siguiente: Área con Plaga presente: región administrativa o área del territorio nacional, en la cual la plaga ha sido detectada y/o ratificada su presencia por parte del Servicio.

Drosophila suzukii (Matsumura) (Diptera: Drosophilidae), the spotted-wing drosophila, is an invasive pest of fruit crops, which appeared in eastern Canada in 2010. Les adultes mesurent entre 2,6 et 3,4 mm avec une femelle généralement plus grosse que le mâle, facilement reconnaissable grâce aux deux taches noires sur les ailes (les taches apparaissent une dizaine d’heures après l’émergence et sont à leur maximum d’intensité à partir de deux jours). Strawberries deteriorate quickly. Drosophila suzukii density is higher in complex landscapes. D. suzukii was first detected in Switzerland in 2011 [].While at first only sporadic local crop damage occurred, in 2014, D. suzukii imposed severe economic burdens on growers of berries (e.g., strawberries, raspberries, blueberries), stone fruit (e.g., cherries, plums, apricots) and grapes, thus raising much public concern and media attention.
