SUMMARY: A survey was made from late 1976 to late 1977 to determine the extent of resistance to acaricides in the cattle tick Boophilus microplus in Queensland. Questionnaires and requests for samples of ticks were forwarded to more than 900 randomly

As part of a continuing programme to aid in the development of new acaricides, the potentials of three synthetic pyrethroids, permethrin, cypermethrin and decamethrin, were assessed against a range of resistant strains of the cattle tick (Boophilus m

The effectiveness of ten acaricides against Boophilus microplus (Can.) on cattle in southern Queensland, Australia, was investigated in 1960–63. Of infested cattle dipped in or sprayed with each acaricide, some were kept in stalls so that observati

The deposition and loss of DDT from various DDT formulations sprayed on to cattle were investigated as part of a general study aimed at increasing the persistence of acaricides on cattle. Exceptionally high DDT deposits resulted from several types of

Nine ready-to-use pour-on formulations were tested for systemic control of an acaricidal-susceptible strain of Boophilus microplus (Canestrini); the active constituents were bromophos, bromophos-ethyl, bromophos-ethyl + chlorfenvinphos, chlorfenvinph

SYNERGISM studies with the cattle tick Boophilus microplus have been effected by enclosing larvae in packets impregnated with olive oil solutions of the test chemicals and recording mortality after 48 h1,2. In these conditions larvae exposed continuo
