Data are presented from initial tests to determine systemic effectiveness against cattle grubs. Hypoderma spp., of 9 insecticides found systemically active in laboratory sreening tests, and of 14 insecticides which had previously shown some activity in cattle grub test. Those treatments found highly effective against cattle grubs, Hypoderma lineatum (de Villers) and H. bovis (L.), were: Bayer 37341, O,O- dimethyl O-[4-(methylthio)-3,5-xylyl] phosphorothioate, in feed at 2.5 mg/kg/day for 10 days; Bayer 37342, O,O- dimethyl O-[4-(methylthio)-3,5-xylyl] phosphorothioate, in feed at 5 mg/kg/ day for 10 days; butonate, in feed at 2.5 mg/kg/day for 10 days; Famophos®, O-[p-(dimethylsulfamoyl) phenyl] O,O-dimethyl phosphorothioate, pour-on of 65 or 125 ml/ animal of 12.5%, or 100 ml/animal of 16.7% formulation; fenthion, in feed at 1 mg/kg/day for 10 days: Imidan®, O,O-dimethyl S-phthalimidomethyl phosphorodithioate, 10 mg/kg by intramuscular injection, pour-on of 125 and 250 ml/animal of 2% in oil, 250 ml/animal of 2% in water, 250 ml/animal of 1% in oil; Stauffer R-2964, 2-mercato- ethyl methyl carbamate O,O-dimethyl phosphorodithioate, 0.5% spray; Stauffer R-3828, S(p-chlorophenyl) phenyl-methyly O,O -diethyl phosphorodithioate, 50 or 100 mg/kg by capsule; trichlorfon, in feed at 5 or 2.5 mg/kg/day for 10 days, sprays of 0.5-1.5%, and pour-on of 8 oz/animal of 6% in water; and Vamidoate, O,O-dimethyl S-[2-[(I-methylcarbamoylehtyl) thio]ethyl] phosphorodithioate, in feed at 7.5 mg/kg/day for 10 days.
