ABSTRACT

A report of a multiple resistance case of Boophilus microplus (Acari: Ixodidae) in Padilla, Tamaulipas state, Mexico, is presented. Ticks larvae showed resistance against all ixodicides tested in the larval packages resistance test: chlorfenvinphos, coumaphos, diazinon, lindane, cipermethrine, deltamethrine and flumethrine. The greatest resistance was related to the permethrine group, being higher than 47%. For organophosphorus, larvae resistance was less than 31%. The less effective ixodicide was cipermethrine, having more than 85% resistance.
