You want to get quality seed. If you really want to grow the big big ones, you'll need to purchase seed from a plant that produced a giant pumpkin. The ones sold in the stores in packets as Big Max or Atlantic Giant will get you big pumpkins, but not giant. It's a good place to start, though, if...
The beetles look like this, or have spots and I bought yellow sticky traps to trap them, and I squish them whenever I can. The traps work pretty good with the squishing.
Honestly, though, you could have a lot of bugs that's doing damage to a wide variety of plants.
Too early this year for massive failure, but I'll gladly share last years, hopefully some of it will make you smile:

My first year growing carrots...
I have icicle radishes in with all of my cucurbits but they don't seem to be attracting anything. They're almost ready for picking, still waiting for them to bolt.
I need some assassin bugs!
Too much fertilizer? They won't make fruit if there's a lot of fertilizer.
Bad weather? Too hot, too dry?
Wish I had known to plant chard to defect bugs, went outside and squished 11 squash bugs in about 3 minutes; and that's the 4th time I've been outside today to squish.
Totally agree! I was lucky enough to have some wild blackberries on my property... once they start producing I pick daily and freeze what I don't eat. Nothing better than a blackberry cobbler or crisp in the middle of winter.
Yeah, it's hard to win here with the weather (while the rest of you are are sweating we're still in the 55-65 range at night), the animals (deer/groundhogs), the bugs and slugs, the hail... and then destructive chickens (which thankfully aren't so destructive this year).
Just went out and...
The above squash bug picture was last year's horror. I've vowed to be more proactive this year. I'm squashing the bugs daily. So far it's been minimal, although the cucumber beetles are out of control.
Welcome, gotcha added. To get a bigger pumpkin, you'll have to sacrifice quantity for quality, meaning choose only 1 or 2 of the best looking pumpkins on the vine, and cut the others off. That way the plant puts energy into less pumpkins, meaning more growth. It's hard to do.
The cucumber...
