Four systemic insecticides incorporated into the diet of hooded white rats killed all of the oriental rat fleas, Xenopsylla cheopis (Rothschild), with which the rats were infested; the fleas died without producing progeny. The lowest effective dose of each insecticide, expressed in mg insecticide eaten per kg body weight per day, was: diazinon 14.4, fenthion 4.1, mirex 6.1, and trichlorfon 38. Four other insecticides, butonate, dimethoate, menazon, and Thiocron® (O,O-dimethyl phosphorodithioate S-ester with 2-mercapto-N- (2-methoxyethyl) acetamide), were ineffective.
