Early Season Codling Moth Trap Monitoring
While monitoring for Codling moth (Cydia pomonella) at the beginning of the field season care must be used when identifying the moths you catch in your traps. During this part of the season there is another moth that closely resembles Codling moth. This moth is referred to as the “Sage moth”, Grapholita imitativa. This moth is native to the Western US, but there is little information on host plants. It probably shares some pheromone components with the Codling moth and is active around the same time as Codling moth first flight and is often captured in pheromone traps set out to monitor Codling moth. Misidentification of this moth as Codling moth can cause erroneous conclusions about early season codling moth risk in an orchard resulting in too early application of your control measures.
