Three 35-game cock groups, designated Groups I, II, and III, and further subdivided into 3 subgroups, named A, B and C of 15, 15, and 5 cocks respectively, were subjected to 3 different treatments of 10% Cypermethrin baths. Groups I, II, and III were given baths once weekly, every 2 weeks and every 3 weeks, respectively. All subgroups A and B were bathed with 1:1000 and 1:1500 10% Cypermethrin, while all subgroups C were bathed with water. Suspected trombiculid lesions were counted a day prior to each scheduled treatment. The mean count of the lesions was reduced to zero after 2 treatments for A and B of Groups I and II, while that of Group III was not able to show reduction to zero after 3 treatments. Estimated marginal means and Sidak’s test showed that a weekly treatment would more significantly reduce the lesion count and that between bathing the solutions that of A (0.005) was significantly less than that of B (1.354), which was also significantly less than that of C (2.1600). Thus, this study showed that the 10% Cypermethrin bath could reduce the number of suspected trombiculid mite lesions and that the 1:000 concentration applied once every 2 weeks was the best concentration and frequency for usage.
