Hmmm 'those' indicates to me that you have quite a few. Tomato hornworms primarily attack tomato plants but sometimes will go for potatoes and even peppers. I've never experienced an infestation of them. Last year I had one. Sometimes they are difficult to detect, but upon close inspection you should be able to see small black dots similar to mice droppings at the bottom leaves of the plant. The larva feeds on the foliage and sometimes the stems. If left alone it could cause severe damage to the plant. Inspect the hornworm, if it's parasitized (has a white grain, similar to a rice grain) anywhere on it's body, leave it alone. It is the egg of a braconid wasp. The larva that hatches from this egg feeds on the insides of the hornworm and eventually kills it. If however there are no signs of the eggs, you can hand pick it. Some people use Bt, I use the handpicking method. Good luck.
