<div>SWD has been found in intact peaches in NY this year. Infestation levels are low. Growers are using insecticides. I have sampled 10 varieties. Sampled prunes this week; nothing found with salt float, now waiting rearing results. Sampling one peach variety
after harvest was completed showed the level of infestation went up as the variety softened on the tree.</div>
<div id="AppleMailSignature">I sampled intact peach drops some years back and found about 1/3 of the Drosophila reared out were SWD.</div>
<div id="AppleMailSignature">SWD was early and very bad in NY. Tart cherries significantly affected on at least 3 farms.</div>

<div dir="ltr">Case in Maine that appears to be SWD attack on intact peaches without splits or other prior wounds. These peaches were ripening on the tree but not over-ripe and no splits etc. for easy drosophila oviposition without having to cut through skin.
Until now it seemed that SWD could only lay eggs in peaches with pre-existing wound. Have other folks seen SWD infestation of intact peaches?
