Abstract
IN a mixed flock of 147 poultry, 101 birds were infested with Cnemidocoptes mutans. Of these, sixteen were very severely affected. A series of preparations containing the gamma isomer of benzene hexachloride in dilutions of 0·1 and 0·5 per cent in various vehicles were used. Mild and moderate cases were freed from the infestation after one treatment, while after two treatments at an interval of a week only two birds continued to harbour living mites. The poultry houses were sprayed with benzene hexachloride in miscible oil, giving a deposit of 200 mgm. gamma isomer per sq. ft. A fuller account of the experiment will be published elsewhere.
