Resumo(s)
Since the accidental introduction in Portugal officially in 2012 (EPPO, 2012d), Drosophila suzukii (Matsumura) became a pest with high economic impact in small fruit crops. On IPM, monitoring and risk assessment is mandatory, therefore the possibility of using traps has enormous interest. The monitoring of this drosophila´s populations can be done with food traps.
The goal of the present study is to contribute to a better knowledge about D. suzukii adult fly´s attraction to different traps (devices and baits). The work was developed in two farms, using three devices (transparent cup with or without yellow adhesive sticky trap, red cup DROSO-TRAP® from Biobest, trap made with water bottles) and four baits (vinegar, mature fruit, DROS’ATTRACT® liquid from Biobest and yeast). Spotted wing drosophila catches rose when fruits began to mature in the crop. Regarding the devices the red cup DROSO-TRAP® and the transparent cup were the most efficient devices. The yellow sticky trap did not raise the number of adults captured. Regarding the baits, the yeast mixture and the DROS'ATTRACT® captured higher number of adults than fruit and in some trap combinations also than vinegar. We captured more females than males.
