2017-09-18 Thread Glen Koehler
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

Yes, first saw it in nectarine mid-September two years ago. Very ripe, but intact fruit still on trees. SWD love damaged peaches, try to get them all picked before they get too soft.

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 l

Hello from the Atlas Mountains in Morocco, I hope somebody on the list can help me find the reason our two-year pear trees produce a honey-like sticky substance. I was told it is pear psyllia, but I do not see any insects on the trees. Somebody else suspected gummosis. I am familiar with gummos
