My family's nectarine tree has been infested with these small larvae, so far I've only seen one per fruit across several dozen fruits, that seem to bore their way from the surface towards the pit and then leave a bunch of droppings near the pit. What are they and how can we get rid of them?
common nectarine problem insects All I know is I will forever be looking before biting into a nectarine or peach or apricot again!!
Pretty sure you've got more than one insect in that fruit. Pnuts is correct for that gross larva; Peach Twig Borer. Wasn't listed in the bulletin I sent but you might check out the beetle and the thrip. Ugh. Tell me you didn't bite into this nectarine!
The Bulletin is excellent about how to deal with the insects it talks about but the preventative measures I think would apply for all insects. There are also beneficials you could use that actually control the numbers of insects very well.
