Apple fruit infested with codling moth are more attractive to neonate codling moth larvae and possess increased amounts of (E,E)-alpha-farnesene
Journal of Chemical Ecology 26 (7), 1685-1699
Abstract: Apple fruit artificially infested with codling moth larvae attracted significantly more neonate larvae of the codling moth, Cydia pomonella than uninfested fruit. A greater number of larvae responded to odor in an olfactometer from codling moth-infested cold-stored Red Delicious thinning apples than uninfested apples. Immature Granny Smith, Red Delicious, or Golden Delicious apples that were infested on the tree for five days by codling moth larvae were more attractive to neonate codling moth larvae than similar but uninfested fruit of the same varieties. Apples infested on the tree and sampled five days later also contained significantly greater amounts of the larval attractant (E,E)-alpha- farnesene, compared to uninfested apples. Other types of injury to apple fruit did not produce results similar to that from codling moth infestation, either in increased attractiveness to codling moth larvae or in increased quantities of (E,E)-alpha- farnesene. These results are consistent with the reported attractiveness of (E,E)-alpha- farnesene to neonate codling moth larvae.
