Carpovirusine (codling moth granulosis virus)
Carpovirusine is a biological insecticide registered for the control of codling moth in apples, pears, and walnuts. A codling moth larva must ingest the virus in order to become infected. Larval mortality is not immediate, but infected larvae will stop feeding within a few days and eventually die. Multiple applications per generation are recommended for the best efficacy of this product. The first application should be made at the beginning of egg hatch and repeated every 7 days. Mating disruption in combination with codling moth granulosis virus should provide very good control of pesticide-resistant codling moth populations. In laboratory tests conducted at the Penn State Fruit Research and Extension Center, codling moth granulosis virus was also effective in controlling neonate Oriental fruit moth.
