Small Fruit Fly Packs Hefty Economic Punch

 OVERVIEW

  • Infests berries and stone fruits
  • Attacks healthy ripening fruit as well as damaged fruit
  • Lays eggs inside ripe fruit
  • Widely distributed

The Spotted Wing Drosophila (SWD), a native of Southeast Asia was first detected in North America in Santa Cruz County, California in 2008. Since that time, the pest has spread throughout multiple states and into Canada.

SWD is distributed globally in most temperate soft fruit producing areas with the exceptions of South America, New Zealand and Australia.

In addition to rotting fruit, this species readily attacks undamaged fruit which can also cause additional damage by secondary fungal and bacterial pathogens. Females lay eggs under the skin of ripening fruit. When the larvae hatch, they begin feeding within the fruit escalating soft tissue damage and creating entry  points for pathogens.

Monitoring for SWD activity is important to detect populations to minimize damage as harvest approaches. Alpha Scents traps are low-cost, convenient and ready to use. No water or drowning solution is required.
