Estudo da infestação de fêmeas bovinas de diferentes grupos genéticos por ectoparasitas.

Abstract

Countings of Boophilus microplus (NCAR), Haematobia irritans (NMOS) and Dermatobia hominis larvae (NBER) were dane on Nelore (NE), Canchim x Nelore (CN), Angus x Nelore (AN) and Simental x Nelore (SN). The genetic group and the physiological state of the female affected NCAR and NBER, while the counting (season) and the genetic group x counting interaction affected ali traits. NE females showed less ticks than CN which showed less ticks than AN and SN. AN showed greater NBER than the other groups.
