Bean pod borer moth, Maruca vitrata, is a significant pest of legume plants (Fabaceae). The caterpillars feed on a wide range of plants in the legume family. They are currently found in Mexico and other pantropical regions. In Florida, this pest threatens peanut, pea, and green bean crops. They are occasionally trapped in Florida, Louisiana, and Texas. This March, DPI collected an adult bean pod borer at a light in Monroe County. No additional moths or larvae were detected in the area, but further monitoring efforts will continue for this pest.

Adult bean pod borer moths look similar to other pest moths in Florida. Professional identification is necessary to determine the species. Growers are encouraged to inspect plants for symptoms, such as bore holes in pods and flower drop.

Caterpillars are cream in color with dark spots. Infected pods will exude caterpillar frass and show signs of decay.
