Extension Programs Monitor New York Vineyards for Exotic Pests


By Tim Martinson


Grape extension programs from Long Island to Lake Erie have placed traps and lures in 40 vineyards to detect potential exotic pests as part of the Coordinated Agricultural Pest Survey funded by the New York State Department of Agriculture and Markets.

The Cooperative Agricultural Pest Survey (CAPS) provides early detection of exotic plant pests before they become established. With funds from the USDA, the New York State Department of Agriculture and Markets' Division of Plant Industry is supporting the deployment of traps with pheromone lures in 40 locations throughout New York by Long Island, Hudson Valley, Finger Lakes, and Lake Erie grape extension programs.

Traps will be serviced every two weeks from early July through September for detection of five potential exotic pests not yet present in New York: the silver Y moth, light brown apple moth, European grapevine moth, false codling moth, and summer fruit tortrix moth.

In addition to these targeted pests, Cornell Hudson Valley Fruit Laboratory entomologist Peter Jentsch is leading the effort to monitor for two additional invasive pests, the brown marmorated stink bug (already present in the mid-Atlantic region) and the spotted wing drosophila. Jentsch has supplied specialized traps to other New York regions for these pests.

New York State Integrated Pest Management specialist Tim Weigle is leading the project, which also involves Alice Wise (Long Island – Suffolk County CCE), Peter Jentsch and Steve Hoying (Cornell-NYSAES Hudson Valley Laboratory) and Hans Walter-Peterson (CCE Finger Lakes Grape Program).
