I think the cucumber beetles took down my Yellow squash too. I pulled one on Monday and the other one doesn't look very good either. Last night while watering my butternuts I noticed a few squash bugs scurrying for dry ground.

Rotation doesn't seem to help much for me on cucurbit pests nor does timing. One of them eventually seem to find just about everything but I can usually get a decent crop of summer squash and cucumbers before the plants go south. I am growing the butternuts and acorn squash for the first time in awhile and they were both planted in early June after potatoes and lettuce finished up. They are both just now starting to bloom so time will tell if they will make.

I delayed potato planting because neighbor says if he waits until after June 1, he never gets Colorado potato beetles. I saw some on June 2 on the plants that grew from potatoes I missed last year. The newly planted potatoes are just breaking ground and will get hilled. My summer squash looks ok but I planted before I planted winter squash so that's why I'm wondering if I planted earlier the plants would have been old and tough enough to survive beetles.

I'm sorry about the winter squash, hope you have lots of other successful crops to fall back on!

It's my first year noticing stripped cucumber beetles here. My three cucumber vines are 2 to 3 feet tall right now, so not terribly vulnerable. The first blossoms are opening this week, so I'm a bit more wary now. It's not an all-out assault yet and damage has been minimal so far, but I can usually see a dozen or so beetles around them at any time. A bit of nibbling shouldn't do much harm, I just hope they don't infect my plants with bacterial wilt.

I've been squishing them so far and might pull out the old Shopvac to suck them off, as several can get away before I grab them. They usually hang out in the folds of the compact new growth or in open blossoms.

Sevin handpicking is not enough. I hate it but had no choice, Even 2 times a day 7 days a week was a lost battle.
