Diflubenzuron, uses

Since diflubenzuron toxicity seems to be similar in both insects and cmstaceans, extreme care must be taken when this compound and other chitin synthesis inhibitors are used for insect control in areas where aquatic crustaceans occur. Otherwise, ecological instability may result, with consequences for feeding, metabolism, growth, reproduction, and survival of numerous nontarget organisms. Specifically, diflubenzuron use in salt marsh mosquito breeding areas or on agricultural lands less than 5 km from coastal areas is not recommended because of concerns that runoff may reach the adjacent estuaries, which are the primary hatcheries... 

The high insecticidal activity of Du 19111 against the larval stages of several lepidopterous, coleopterous and dipterous insects and its unique mode of action prompted us to synthetise several hundreds of benzoylphenyl ureas and to evaluate their insecticidal potency in laboratory tests and small scale field trials (4, >, j6). These and other studies led to the ultimate choice of diflubenzuron (il) as the optimal derivative for further development.
