Are you asking about squash bugs or squash vine borers? The C. moschata group of squash/pumpkins are resistant to SVB. Squash bugs (stink bugs) are more of a nuisance than a problem for me, but I don't know of any resistance to them.

I agree with Farmerdilla. Though here, I have had whole plantings killed off by squash bugs. I don't consider Royal Acorn to be resistant to borers. The closest I've found in an acorn, to borer resistance is Scarchuk's Supreme, which I purchased from Sandhill Preservation Center. It was specifically developed for that purpose and did show tolerance. My plants were attacked by borers and managed to keep on growing and producing.

Where borers are a problem I would always go, first, with a c. mochata. Butternuts are all from that family, as is Tahitian Melon Squash. A number of seed companies list their squash with their scientific family names. C. mochata is usually a winner when it comes to borer resistance. C. Mixta is also usually quite resistant, though in my experience its flavor is often less satisfactory. The link below is to Sandhill Preservation Center's squash seed listing. You'll find Scarchuk's Supreme on it.

I don't think any plants are squash bug resistant. I had them everywhere this year. They even were eating my corn. I am using plastic next year and hope that will help some. At least they couldn't keep up with the cucumbers. They were attacking the plants but the plants grew faster than they could attack. I even resorted to spraying but they were back in less than a week. I heard ducks work if you can keep ducks.

Are all varieties of butternut squash resistant to vine borers, or are there various sub-groups which aren't? I'm going to plant various pumpkins and squash in my garden this coming spring, and I'm planting it from stored seed from plants I've boughten at the store this autumn, so I'm unsure a lot of the times as to what variety I might actually be planting.

i truly wish that i had other people's luck with squash bugs so that i could just call them a nuisance. They are absolute destroyers of all cucurbits at our place. They have been horrible here for going on 3 years- this year's problems were accentuated by a severe drought.

I will say that they seem to destroy hubbards first (making trap cropping a real possibility), along with white pumpkins and heirloom pumpkins. the racer pumpkin that is sold by Johnny's is the only one that actually gave me any pumpkins this year.....and i planted 9 varieties. Even though i only got one pumpkin variety i seemed to get a lot of delicata and a some butternut. gold acorn was a bust but table queen did ok, just small because of the drought. If you plant the melons and watermelons near the winter squash your melons will be last on thier buffet. this year i tried to start them late but have realized that i should have started them very early instead.

At least we got some winter squash, pumpkins and cucumbers this year- last year everything was killed by the bugs before fruit got a chance to set. This year we did some major hand picking of eggs, which i think helped us maintain at least some harvest. It is at times like these that i understand why people use sevin.... oh well, i truge along with my 'no spray'...

I have no problem with vine borers so if that is your problem then the other posters would know better about that.
