Survey Information

The False Codling Moth (Thaumatotibia leucotreta) is a potential pest of many different horticultural and native plants. Its larvae bore into and feed on the fruit. Surveys are conducted because of the presence of potential host material in Wyoming. It was found in California in 2008.

The Wyoming False Codling Moth Survey is conducted by the Wyoming Pest Detection / CAPS Program. A delta 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.
