Tomatoes, row cover, and pollination

I have some tomatoes under row cover, there are some really rowdy volunteer squash in there that haven't gotten squash bugged yet, so I don't want to open the cover until I must. I just saw green tomatoes on one of the plants. I thought tomatoes had to be pollinated to set fruit? Or is it just to set fruit with viable seed? If I can get away with leaving them covered, it would make me happy. There are a few bugs in under the net, not many.

I lost 95% of the things I planted last year to fungus or bugs, so the longer I can keep the cover on, the happier I'll be.

Tomatoes are self pollinating but the squash need insects especially squash bees.

Thank you!
Yeah, I was waiting on the squash to need it before I opened it, the squash bugs here are ravenous. I'd like to get some squash this year... Last year I had 80+ plants, another 60 seed or so seeds of 20 some varieties, I got 3 tromboncino. :(

Wonder if I can drape off just the squash flowers, leave the rest covered. hm....

Squash bugs over winter in mulch and soil and now it's the time they come out to breed the next generation. Have you check underneath the leaves to find any eggs? I have destroyed over a thousand eggs trying to disrupt their life cycle. Squash bugs didn't kill my squashes last year, powdery mildew did. I still want to keep their numbers at minimum.

I haven't checked the plants in the last few days, I am trying to watch them. I killed thousands last year, eggs, babies, and adults. What the fungus didn't get, the beetles did.
I wondered if they were in the soil under the row covers... Thank you
Need to check them
Last year by this time I had nothing but deadness, this year I have at least some trying, the ones under the cover, and some that are climbing my new arbors. I love squash, hate to have to buy it.
