Steve, I seem to recall Michael Phillips' book saying that the apples that drop with curculio have better survival than those that stay on the tree because the apple growth can sometimes crush the larvae. Pear drops, on the other hand, are so hard and stoney that they can't mature in them. I'm away from my copy of the book right now so I can't check on that. I don't remember what the deal was with the CMs. Muffy Barrett

Howdy,
I am thinning apples now. Is it imperative to pick up every fruit?
I understand that curculio won't emerge from fallen apples.
There is some codling moth, maybe one in every 30-40 apples have frass. Will codling moth emerge from fruits I leave lay or that I toss on the top of the compost? Or, since the grubs are fairly small will they croak?
I haven't yet sprayed my first of two imidan sprays. I plan to do so when I'm done thinning. I imagine that the apple maggots have started to fly around, too. How long do the larvae have to be in the fruit for them to be able to emerge from the apple and dig into the soil for overwintering.
Ideally, my hope is that I can safely leave the damaged fruit on the ground without increasing my pest populations. I do plan to pick up all the drops that fall later in the year through the end of the harvest. By the time the apples are big enough to drop on their own from about August 1 or so onward I'm quite sure that at least the apple maggot would be mature enough to bury itself into the ground, waiting to annoy me again next year.
Any other thoughts on "danger" posed by drops?
Thanks,
Steve Herje, Lone Rock, WI USDA zone 3/4, where the first usable Vista Bellas are dropping. They're small but have some color and will bake up into the first pie of the season.
