The efficacy of maximum label rates of bifenthrin applications to dry tires to prevent Aedes mosquito breeding was investigated through field colonisation and field bioassay trials. The effect of tires situated in shaded and unshaded locations was also investigated. Aedes notoscriptus and Culex quinquefasciatus larvae were the most abundant species present in the field colonisation trial. Colonisation of tires by Ae. notoscriptus larvae occurred significantly sooner in shaded compared with unshaded locations (P = 0.002), and bifenthrin applications in shaded tires only prevented colonisation for 2.5 weeks. Aedes notoscriptus larvae were not found in the unshaded tires until week 9. Culex quinquefasciatus colonised treated tires from the 2nd week in both shaded and unshaded treatments. In the bioassay, water from bifenthrin treated tires was found to kill 100% of Ae. notoscriptus for only 2.0 weeks in shaded and 2.2 weeks in unshaded treatments. Bifenthrin residual applications therefore cannot be relied upon for preventing mosquito breeding in tires for greater than 2 weeks.******** Note the American spelling of road vehicle tyres.
