Screw-Worm Control with Insecticide Sprays1

Abstract
Experiments were conducted to find a safe an inexpensive insecticide that is toxic to young larvae and has a 2-day residual effect. In laboratory tests Bayer 22408 ( O,O -diethyl O -naphthalimido phosphorothioate) gave excellent control of screw-wroms ( Callitroga hominivorax (Cqrl.)) in sheep. In field trials it performed as well as Co-Ral® ( O (3-chloro0-4-methylumbelliferone) O,O -diethyl phosphorothioate) on sheep but not no cattle. Further critical laboratory tests confirmed the field results.
