Got this from an e-mail newsletter from the Ohio extension service. I know, I know. I can hear the little buggers laughing at me from inside the stems of my pumpkins plants, but maybe... just maybe.

"This pest can be controlled by a preventive strategy of insecticide sprays directed at the base of plants. At sites where this pest is a significant problem every year, sprays are needed once per week for 4 weeks, from late June until late July. At sites where this pest is a minor problem, only two sprays are needed, in early July and 10 days later. A pyrethroid (Pounce, Asana, Capture) or endosulfan (Thiodan) are most effective."
