They bore into the fruit, feed, leave and pupate in the same way as generation one. Moths emerge in early February and March, repeating the process yet again. However the resulting grubs spin cocoons and over-winer in them. They pupate the following spring. Codling moths fly at dusk, from October to April.
Traps give early warning of the presence of codling moth.
They catch moths on a sticky inside surface. Pheromone traps give early warning of codling moth infestations and allow us to carry out cost-effective eradication programs. Contacts If you find an apple or other pome fruit with a frass-filled tunnel reaching into the core, take it to the nearest Agriculture Western Australia office for identification. Other pests, such as the light brown apple moth and fruit fly can cause damage similar to codling moth, but these insects do not tunnel to the core and eat the seeds. Most important, do not bring fruit into WA from the eastern states or from overseas.
