Spotted Wing Drosophila
COMMON NAME:
Spotted wing drosophilaSCIENTIFIC NAME:
Drosophila suzukiiORIGIN:
Southeast AsiaDESCRIPTION:
Spotted wing drosophila (SWD), Drosophila suzukii, is an insect pest of economically valuable, small fruit and tree fruit crops. Known in Oregon and the Pacific Northwest since about 2009, this species now appears to be established in many fruit growing regions around the country.HABITAT:
SWD is found in moderate climates between 40° and 68° Fahrenheit.THREAT:
SWD impacts many fruit crops including raspberries, blackberries, blueberries, strawberries, sweet cherries, peaches, grapes and tomatoes. SWD lays eggs inside fruit, unlike other species which lay eggs on top of fruit. The larva then eat the fruit from the inside, causing it to collapse. SWD infestations can lead to up to 80% crop loss.MANAGEMENT:
Growers and researchers are working together to implement effective pest control strategies.
