These insecticides and the following 8 systemically active insecticides (previously tested) were administered orally or dermally to cattle for control of cattle grubs, Hypoderma spp: Bay 62863 (2,3- dihydro-2-methyl-7-benzofuranyl methylcarbamate), Bay 64995 (O,O-dimethyl phosphorothioate O,O-diester with 4,4'-dithiodiphcnol), Bay 65258 (O-ethyl-S-methyl phos- phoramidothioate), carbofuran, menazon, Schering 34615 (m-cym-5-yl methylcarbamate), Stauffer B-9627 (0,0- dimethyl phosphorodithioate S-ester with mercapto-2-propanone diethyl mercaptole), and Stauffer R-3828 (S- (p- chloro-a-phenylbenzyl) O,O-diethyl phosphorodithioate). Only Bay 64995 (15 mg/kg) and Stauffer B-9627 (20 mg/kg) administered orally by capsule gave> 90% concaptoethyl) trol of the grubs.
