Field Studies of Certain Benzene Derivatives as Larvicides and Wound Protectors Against the Screwworm

Abstract
In field tests during 1938 and 1939 in Kimble and Menard counties, Tex., animal wounds infested with screwworms, Cochliomyia americana, were treated with the following larvicide and wound protectors: pine tar oil, diphenylamine, p-nitrophenetol, diphenylene oxide, and mixture of diphenylamine 95% and Ca stearate 5%. Diphenylamine was the most effective wound protector tested. Addition of Ca stearate to diphenylamine to prevent caking decreased the effectiveness of diphenylamine as a wound protector.
