Evaluation of lures for attracting both sexes of tortricid moths in apple orchards

Apple orchards are often attacked by a number of tortricid (Lepidoptera) pests (e.g. codling moth (Cydia pomonella) (CM), oriental fruit moth (Grapholita molesta) (OFM), and redbanded leafroller (Argyrotaenia velutinana) (RBLR)) that are either key or secondary pests. Sex pheromone-based lures have been used to monitor male moth populations and to control pest species directly via mating disruption. This study focuses on evaluating kairomone-based lures for optimal capture of both sexes of individual or multiple species of tortricid moths. The results show that, across the entire season, Megalure was as attractive or more attractive than the pheromone lure CML2-P to male OFM, whereas CML2-P was numerically more attractive to male CM than Megalure. Megalure attracted the most females of both species but the addition of plant volatiles (i.e., TRE2265) to Megalure did not improve female captures. The lures TRE2266 and TRE2267 performed well at attracting male RBLR and OFM. This type of multi-species and both sexes attractant lure shows prospect of developing cost-effective monitoring as well as mating disruption of multiple tortricid species at the same time.
