A previously described bioassay was modified to assess the response of the poultry red mite, an important ectoparasite of fowl, to a selected group of acaricides. The adapted bioassay is simple to use, escape-proof and provides data that can be subjected to probit analysis. The reproducibility of the method was assessed by three tests with α-cypermethrin against a reference strain, which produced dose-response lines that did not differ significantly ( χ 2 = 1.39, 2 d.f., p = 0.50), and had a derived common slope of 1.89. In addition, a limited evaluation study enabled assessment of response to commercial formulations of bifenthrin, bifenthrin + malathion and cypermethrin by field populations of the poultry red mite.
