As a follow up to yesterday's post about the dying zucchini, it seems I have a case of Squash Vine Borers. I pulled up the dead plant last night and the main stem broke off in my hand just an inch or two above ground level. What I found looked much like the two pictures at the bottom of the page I've linked to. Big white juicy grubs, three of them, squirming around in a rotted stem. I've put them in a trash bag and tied it off. Now I'm on the lookout for frass (a golden cornmeal-like substance that appears around the holes once the little grubs burrow into the stems). I haven't seen any more yet, but I'm paranoid.
The really annoying thing is I saw a pretty looking new insect in the garden yesterday and spent over an hour searching on the internet trying to figure out what it was. I never found a satisfactory match. Then this morning, my husband found a photo of the adult moth form of the squash vine borer. I'm 100% positive that's what I saw yesterday. If only I'd known! I should have killed it then and there...UGH!
