Monitor flights with pheromone traps. Early planted beans, corn, and melons are susceptible to seedcorn maggot damage. Larvae chew leaves of current and gooseberry. Damage starts in the interior of shrub. Millipedes and slugs tunnel the ripening berries.
Adults are present on cabbage, radish and related plants.
Moths move to mountains with warm weather. Peak crawler period often occurs in early June. Monitor infested trees. Highest populations of leaf vagrants present. Damage will end soon.
