Commercially available plastic and other types of flexible tubing were tested to determine their relative permeability to an emulsifiable concentrate (EC) of permethrin acaricide. Bioassays employing northern fowl mites, Ornithonyssus sylviarum (Canestrini and Fanzago), indicated that .3 mg permethrin/cm2 surface area penetrated vinyl plastic tubing that had been filled with 42.5% active ingredient EC for 14 days. Vinyl tubing circuits were installed in wire poultry cages, either in the form of suspended loops or woven through the rear cage wall, and permethrin EC was introduced by means of a small pump. Significant reductions in northern fowl mite populations on hens caged therein were apparent after 48 days posttreatment. This approach has merit as a long-term, labor-economical form of mite control on caged poultry.
