Spotted Wing Drosophila (SWD) Monitoring Network New York – 2017

Abstract

Spotted wing Drosophila (SWD) arrived early with most sites reporting continuous trap catch from the first trap catch date forward. As of August 7, 2017, all of the 32 SWD trapping sites had caught SWD in the 21 counties in New York where traps were deployed. This contrasts previous years in which first trap catch might be followed by a week or more of zero SWD trap catch. Also, in prior years there were often sites in which first trap catch was in late August or early September. To prevent fruit infestation this year, susceptible fruit crops had to be protected with an insecticide spray program or have exclusion netting in place.
