This document discusses chitin synthesis inhibitors, a class of pesticides that interfere with the formation of chitin in insects. It begins by explaining that chitin inhibitors disrupt molting and development by blocking the formation of chitin, the building block of insect exoskeletons. Without the ability to synthesize chitin, molting is incomplete and insects die. The document then provides details on several specific chitin synthesis inhibitors, including their trade names, formulations, modes of action, and target pests. It focuses on diflubenzuron, flufenoxuron, chlorfluazuron, triflumuron, teflubenzuron, novaluron, bupro
