A bioassay technique was developed using a rodent mite as the test. organism. With this technique the true systemic nature of acaricidal action of orally administered Sevin® (I1-naphthyl N-methylcarbamate) in poultry was demonstrated. The systemic activity lasted 1 to only 1 to 3 days after treatment.. Seven was demonstrated in blood of treated birds by qualitative chromatographic' analyses. Poultry tissues were quantitatively analyzed of Seven following oral treatment. of birds with Seven. The maximum residue found in any tissue taken 24 hours after treatment of a bird at the rate of 150 mg. Seven per kg. body weight was 4.1 p.p.m. in the gizzard. No detectable residues were found in tissues from identically treated birds sacrificed .5 days after treatment.
