Yes. Peeta being "hi-jacked" by Tracker Jacker venom conditioning is a central plot point. In the books he only freaks out when he sees Katniss, but the ending scene in the Mockingjay indicates that might be different here. In the books he isn't freaking out when she's not present. It's basically a form of fear conditioning where images of Katniss are shown to him when he's dosed with the venom and tortured so he's conditioned to freak out whenever he sees her because he associates her with the pain.
