Evaluation of CGA 72662 as a topical spray and feed additive for controlling house flies breeding in chicken manure

Abstract

The insect growth regulator, CGA 72662 (N-cyclopropyl-1,3,5-triazine-2,4,6-triamine), was tested both as a topical spray and feed additive for controlling the house fly (Musca domestica L.) breeding in chicken manure. Dosage concentrations of .025%, .05%, and .1% were sprayed on sections of manure surface in a shallow pit egg layer operation at rates of 1.9 and 3.8 liters/10.2m2. AT 17 days posttreatment each concentration at both rats, except .025% at 1.9 liters/10.2m2, provided at least a 70% reduction of native house flies and 100% inhibition of laboratory reared house flies. CGA 72662 fed to both hens and broilers at rates of 1.5 ppm and 5 ppm provided up to 100% mortality of house flies 1 day after birds were started on treated feed to 1 day after treated feed was removed.
