Abstract
WhenBoophilus microplus and Type-II hybrids (B. microplus females×B. annulatus males) were released simultaneously onto bovine hosts, mating between the two forms appeared not to be at random. There were more contypic and fewer intertypic matings than predicted under an assumption of panmixia. An examination of the patterns of matings revealed that more of the matings on the first two days of detachment were between the two sexes ofB. microplus. Engorged females dropping on the last four days of maximum female detachment were predominantly hybrids mated to bothB. microplus and hybrid males. The non-random mating pattern does not appear to be caused by assortative mating betweenB. microplus and Type-II hybrids, but because theB. microplus were competnet to mate two days before the hybrids and theB. microplus males compete for mates of both types better than the Type-II males.
