Studies were conducted on the toxicity to newly hatched house fly larvae (Musca domestica L.) of the feces of cattle fed 25 different compounds. The materials were incorporated in the animals' diet for 5 days and fecal samples collected for tests at different intervals during feeding and after it was discontinued. Fourteen of the 25 compounds were not completely lethal to the larvae at the dosages tested. Bayer 22408 (O,O-diethyl 0- naphthalimido phosphorothioate) and Co-Ral® (O-(3-chloro-4- methylumbelliferone) O,O-diethyl phosphorothioate), the two most effective materials, were lethal to the larvae when administered to the animals at dosages as low as 1 mg./kg. Comparative data are presented on the susceptibility newly hatched larvae of the house fly, stable fly (Stomoxys calcitrans (L.)), and horn fly (Siphona irritans (L.)) to four of the more effective insecticides.
