Insecticide resistance of Bemisia tabaci

Investigations have been carried out in the UK to assess the resistance of Bemisia tabaci (EPPO A2 quarantine pest) from different geographical areas to organophosphates and pyrethroids. Whitefly populations from Sudan, Israel, Cyprus, Pakistan, UK, Netherlands, Belize and the USA were assessed and compared.
It was found that no strain was fully susceptible to the organophosphates and pyrethroids tested and that most appear remarkably homogeneous in response, with no or little evidence for the presence of susceptible individuals.
