Tick resistance to diazinon: a case report

Alo Odunayo Samuel


A case of a heavy tick infestation of dogs in a private kennel that resisted treatment with diazinon is reported. Application is by the conventional acaricidal tick dips and subsequent acaricidal spraying of the premises on three consecutive occasions which yielded no result. However a change of drug from diazinon to cypermethrin for dips and spraying the premises on a single exposure controlled the ticks. It was thus considered that resistance of ticks to common pesticides have serious implications for tick control and for the safety of the environment.
