In screening tests, 27 insecticides were systemically active when administered orally or subcutaneously to guinea artificially infested with larvae of the screw-worm fly, Cochliomyia hominivorax (Coquerel); or the second- ary screw-worm fly, C. macel/aria (F); and the black blow fly, Phormia regina (Meigen); and nymphal lone star ticks, Amblyomma americanum (L.); and fed upon by stable flies, Stomoxys calcitrans (L.). Of 39 insecticides administered to cattle for the sys- temic control of cattle grubs (Hypoderma spp.) , the fol- treatments were effective (> 90% control) in pre- venting grubs from encysting in the backs of the animals: Bayer 34727 (0,0-dimethyl phosphorothioate O-ester with p-hydroxybcnzonitrile) at 25 mg per kg by capsule and as a 0.5% spray; Bayer 37342 (O,O-dimethyl O-[4-(methylthio)- 3,5-xyly] phosphorothioate) in feed at l mg per kg per day for 10 days: CELA 8-1942 [0- (4-brorno-2.5-dichloropigs phenyl) 0,0-dimethyl phosphorothioate] at 100 mg per kg by capsule; famphur in feed at 2.5 mg per kg per day for 10 days; menazon in feed at 5 mg per kg per day for 10 days and as 1.0 and 1.5% sprays; Shell SD-8949 [1- (2- bromo-4,5-dichlorophenyl) -2-chlorovinyl dimethyl phosadult phatel at 50 mg per kg by capsule; Stauffer N-3055 (0-2,5- dichlorophenyl a-ethyl cthylphosphonothioate) at 10 mg per kg by capsule; Stauffer R-3828 [S- (p-chloro-alphaphenylbenzyl) O,O-diethyl phosphorodithioatel in feed at 5 mg per kg per day for 10 days; and Vamidoate® (0,0- dimethyl S-[2-[(l-methycarbamoyethyl) thio]ethyl] phos, phorodithioate) in feed at 2.5 and 5 mg per kg per day for 10 days.
