Molecular mechanisms of insecticide resistance in the glasshouse whitefly, Trialeurodes vaporariorum
Year: 2011
Type: dissertation
Abstract: BACKGROUND: Trialeurodes vaporariorum (Westwood), also known as the greenhouse whitefly, is a serious pest of protected vegetable and ornamental crops in most temperate regions of the world.Neonicotinoid insecticides are used widely to control this species, although resistance has been reported and may be becoming widespread. RESULTS:Mortality rates of UK and European strains of T. vaporariorum to a range of neonicotinoids and pymetrozine, a compound with a different mode of action, were calculated and significant resistance was found in some of those strains.A strong association was found between neonicotinoids and pymetrozine and reciprocal selection experiments confirmed this finding.Expression of resistance to the neonicotinoid imidacloprid and pymetrozine was age-specific and resistance in nymphs did not compromise recommended application rates.CONCLUSION: This study indicates strong parallels in the phenotypic characteristics of neonicotinoid resistance in T. vaporariorum and the tobacco whitefly Bemisia tabaci, suggesting possible parallels in the underlying mechanisms.
