- Light brown apple moth was recently found in Santa Barbara County for the sixth time. LBAM is a quarantine pest on the United States mainland and can cause serious damage to various crops, nurseries, fruit trees, landscapes, and native plants.
Management: Insecticides like insect growth regulators and spinosyns, biopesticides like Bacillus thuringiensis-based products, natural enemies that include predators and parasitoids are some management options. However, due to its current status in California, use of pheromone traps to cause mating disruption and quarantine practices to restrict movement are important components of current LBAM management. According to Guy Tingos, Deputy Ag Commissioner, Santa Barbara County, movement of nursery stock into Santa Barbara County from areas where LBAM is established should have a thorough inspection and LBAM certification to ensure the material is free of the pest. Movement of nursery stock, cut flowers, fruit or other plant material that can host LBAM out of quarantine area is highly regulated. Tingos also said that commercial farm operations in infested areas should be under compliance agreement for plant movement and public in quarantine areas should not move the host plants out of their property.
For insect identification and information on quarantine regulations contact your local Ag Commissioner’s office.
