When infestations of Amblyomma americanum (L.) on Braford (Brahman X Hereford crossbreed) and Hereford heifers were compared, Braford were significantly less susceptible to infestation by larvae and adults and caused a greater reduction of % molt of nymphs and dry postmolt wt of males. Weight of females and egg mass wt of females collected from Braford were less than wt of females and egg mass wt of females collected from Hereford, but no differences were found between breeds for % hatch of eggs. Periodic sampling showed fewer larvae and females on Braford at the various stages of engorgement.
