Conteúdo: 	Mortality of Tabanus fuscicostatus Hine females, engorged to repletion on bullocks treated with lambda-cyhalothrin impregnated ear tags, or placed on treated bullocks for periods of 15, 30, 45 or 60 s but not allowed to feed, was equal to or greater than 96% while from 0% to 8% mortality was observed for controls. Average feeding time was significantly lower in T. fuscicostatus fed on treated bullocks (33%) than in flies fed on control bullocks, but average engorged weight was not significantly different between treatments. Mortality of T. americanus Forster females, placed on the backs of treated bullocks but not allowed to feed for periods of 15, 30, 45 or 60 s, was 16%, 44%, 76% and 100%, respectively. Results of bioassays which flies were exposed to treated filter paper (LC50) or were topically treated (LD50) are presented per fly and per weight for T. fuscicostatus and T. leneola complex.
