well if there are not many you can sometimes pick them off by hand, toss into soapy water/bucket.
If there are lots you can try spraying either with something organic or not... Do you really mean stalks or the silks? I'd be careful not to spray anything you want to eat too close to harvest. You might try wrapping some duct tape (Fly-Tapes) to see if you can catch them that way. I assume you mean Japanse beetles since that is what most people are having right now?

Welcome! There are a number of different beetles or their larvae that can affect corn, and which it might be can depend on your location. Can you post a picture for us of the beetle, or the damage, or preferably both? Or do you know what beetle it is?

Frillylily gave you some great choices. The only other advice I have is that if you have bean beetles. Bean beetles are highly motivated by yellow. I found this out by leaving out a Nestle quick container that I used to water deck plants. The next day 15 of them drown themselves.
I went to the dollar store and bought 12 bright yellow kids sand pails. I filled them 1/2 way up with water added a little baking soda and dish soap,. That was only so I would not start mosquito farming. For stability I put a rock in the bottom and set them around the garden. Daily 20 or more would drown themselves in each pail. I would take a slotted spoon and remove them. Took a grocery sack around threw the beetles in and tied it tightly shut and put it in the trash. I must have caught over a thousand. I had so many jumping in the buckets I was worried that the new beetles would stand on the dead ones and not die. That's why I used the slotted spoon to remove them. Now I save every yellow container. I caught other bugs too and only one lady bug. Only YELLOW works. I also bought every other color of pail, pink, blue, purple, green, red and orange. I placed them next to my yellow buckets. The other colors did not catch any bugs. Then I moved the other colored buckets around the garden to have their own section. The yellow continued to have beetles and out of the other buckets I only ever caught one beetle in the red bucket. I also think they liked my yellow buckets because it was like a bigger bloom to them. Works in the flower garden too. If you have something yellow set it out there and if they drown themselves yeah!
