During the period from June to September 1987 field tests were conducted in Okinawa Prefecture to evaluate the efficacy of permethrin-impregnated ear-tags for controlling Musca conducens infestation to pasturing cattle. On June 6 two ear-tags impregnated with 15% permethrin were attached to each of all mothers of a herd of beef cattle in Minna Island of the Miyako Archipelago. The number of flies infesting the cattle body was counted twice in a pretreatment survey and then 8 times during the test period. A similar count was made on another herd of untreated cattle. A remarkable reduction in flies (mainly M. conducens) was noted among the treated cattle. Almost complete control was achieved after 18 days, and this state did not change through the remaining period of the test. The efficacy of ear-tags could be ascribed to the marked depending habit of M. conducens to the host in addition to high susceptibility of the fly to permethrin.
