Benzene Hexachloride to Control Cotton Insects

Abstract

In laboratory and cage tests at Waco, Tex., benzene hexachloride dust gave excellent control of several of the more important cotton insects. Control of the boll weevil, An-thonomus grandis, and the cotton leafworm, Alabama argil-lacea, was better than with Ca arsenate. Control of the cotton flea hopper, Psallus seriatus, the tarnished plant bug, Lygus oblineatus, and the southern green stinkbug, Nezara viridula, was equal to or better than control obtained with DDT. Better control of the cotton aphid, Aphis gossypii, was obtained than with nicotine dusts. Poor control was obtained of the bollworm, Heliothis armigera. DDT and heavy dosages of Ca arsenate dusts each gave better bollworm control than benzene hexachloride.
