Survey Information

The European Grapevine Moth (Lobesia botrana) is primarily a pest of grape, but can utilize several other horticultural and native plants as hosts. Its larvae damage the fruit. Surveys are conducted because of the presence of potential host material in Wyoming and the high potential for establishment. It was found in Napa County, California in 2009. To date, it has not been found in Wyoming. Two hundred five total traps have been placed throughout twenty-three counties in Wyoming.

The Wyoming European Grapevine Moth Survey is conducted by the Wyoming Pest Detection / CAPS Program. A sticky trap with pheromone attractant is placed on or near the host plant from May until August. The traps are monitored for suspects and serviced once a month. If suspects are found they are sent to the University of Wyoming for further identification.
