Cyd-X
Cyd-X is a biological insecticide registered for the control of codling moth in apples, pears, plums, prunes, and walnuts. A codling moth larva must ingest the virus in order to become infected. Upon ingestion, the viral occlusion bodies dissolve in the larval midgut and release infectious virions. Larval mortality is not immediate, but infected larvae will stop feeding within few days. Death occurs 3 to 7 days after ingestion of the compound. After death the larva disintegrates and releases billions of new occlusion bodies with virions that may infect other codling moth larvae. At least two to three 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 7 to 10 days later. Mating disruption in combination with codling moth granulosis virus will provide very good control of pesticide resistant codling moth populations. In laboratory tests conducted at the Penn State Fruit Research and Extension Center in Biglerville, codling moth granulosis virus was also effective in controlling neonate Oriental fruit moth.
