garden pests
Last fall I posted this about our quince trees (which have just come into bloom in the past three days -- yay!)
Update: from the Web research I've done so far, this is probably two separate infections: a primary attack by the Oriental fruit moth (the closely-related codling moth would have gone straight for the seeds, rather than honeycombing the flesh), followed by an opportunistic brown-rot infection.
Oriental fruit moths overwinter, and then go through three or four generations in a summer: the first generation eats leaf shoots, leaving them wilted (which we did see last year), while later generations eat fruit. There are a variety of control mechanisms: parasitic wasps (Glabridorsum, Trichogramma, Macrocentrus); pheromones that disrupt the breeding cycle; a new virus brand-named Madex HP; bacteria-based pesticides Dipel (Bt) and Success (Spinosad); chemical insecticides methoxyfenozide, chlorantraniliprole, and flubendianide. I'm calling local garden stores to see what they've got that makes sense on my scale, for an orchard of two (2) trees.

We've got similar issues...sorry I didn't read that last when you wrote it in the fall! dormant oil is supposed to be effective w/o too much toxicity. while there are blooms you can't spray. After the petals fall, try malathion for oriental moth, or sevin.
