Nine recently developed chemicals were compared as potential control agents for poultry ectoparasites. Field tests, upon which the summary of results is based, were preceded by preliminary laboratory tests of toxicity of the materials to baby chicks and to poultry ectoparasites. Atgas persicus (Oken) was effectively controlled by a 1% emulsion of Sevin® (1-naphthyl-N-methyl carbamate) applied as a premise spray in conjunction with a 0.5% emulsion spray applied to the birds at the rate of 1 gallon per 100 birds. Promising but inconclusive results were obtained with Dibrom® (0,0-dimethyl-0-(1,2-dibromo-2,2-dichloroethyl) phosphate) and Korlan® (0,0-dimethyl 0-(2,4,5-trichlorophenyl) phosphorothioate) sprays. A 1% Dylox® (0,0-dimethyl 2,2,2-trichloro-1-hydroxyethylphosphonate) spray applied to premises and birds gave unsatisfactory control of the fowl tick. Menacanthus stramineus (Nitz.) was effectively controlled with the following formulations: Dylox solution, 0.5%, spray, 1 gallon per 100 birds; Korlan emulsion, 0.1%, spray, 1 gallon per 100 birds, in conjunction with nest and litter spray; Sevin emulsion, 0.5% spray, 1 gallon per 100 birds; Sevin dust, 0.5%, 4 ounces per 100 birds. Promising but inconclusive results were obtained with 0.25% Korlan suspension spray. Ornithonyssus sylviarum (C. & F.) was effectively controlled with the following sprays applied at the rate of 1 gallon per 100 birds: Co-Ral® (0-(3-chloro-4-methylumbelliferone)0,0-diethyl phosphorthioate) suspension, 0.1%; Dibrom emulsion, 0.25%; Korlan emulsion, 0.25%; Sevin emulsion, 0.25%; Sevin suspension, 0.5%. A 5% Sevin dust applied by puff duster at the rate of 4 ounces per 100 birds was also effective. Unsatisfactory control followed use of the following formulations: Tedion® (2,4,4',5-tetrachlorodiphenyl sulfone, 80% technical) suspension spray, 0.1%, 1 gallon per 100 birds; 3.6 to 4 ounces per 100 birds of 15%. Delphene® (N,N-diethyl-m-toluamide) dust, 4% Dibrom dust, or 3% Tedion dust; 0.3 ounces of Santocel (a powdery silica aerogel) dust per 100 birds; 1% suspension of Dowco 109 (0-(4-tert butyl-2 chlorophenyl) 0-methyl methyl phosphoramidothioate).
