Unlike most other Drosophila species D. suzukii oviposits and feeds on healthy fruits [6]. Monitoring and trapping. One of Helga George’s greatest childhood joys was reading about rare and greenhouse plants that would not grow in Delaware. Adult females of Drosophila Suzukii damage the surface of the cherry during laying. They can break apart when handled. Unlike most other Drosophila species D. suzukii oviposits and feeds on healthy fruits [6]. Markings consist of bands at the ends of abdominal segments. Spotted wing drosophila is featured in the 2011 Emerging Pest chapter. However, there are an immense variety of traps in use ranging from homemade sugar or vinegar traps to ones that you can purchase. Fly Drosophila suzukii male (left) and female (right) [/ caption] The adults of this insect are flies with a size of 2-3mm, light yellowish-brown thorax, red eyes and abdomen with black bands. Ripe fruit serve as strong attractants for SWD. Picking cherries on time before they overmatter is also a good form of control. However, by using an integrated pest management (IPM) approach, you can control this pest using organic techniques. When temperatures drop below 5 ° C, the female of Drosophila Suzukii enters reproductive diapause and can survive for 200 days. The infestations start when the fruit start to color and continue through ripening. It is critical to remove the fruit with larvae, so they won’t emerge as adults and lay eggs!
