Baseline determination and detection of resistance to imidacloprid in Bemisia tabaci (Homoptera: Aleyrodidae)

Abstract: Adult Bemisia tabaci (Gennadius) were tested with imidacloprid in a bioassay method using systemically treated cotton leaves. The method was simple, robust and repeatable and provided baseline data for a laboratory and a number of recently collected field strains. The LC 50 for imidacloprid susceptible strains was calculated to be 1.7 ppm and a concentration of 16 ppm determined as diagnostic for imidacloprid resistance. Ten strains of B. tabaci collected from the Almeria region of Spain showed significantly l… Show more

“…Bemisia tabaci has developed resistance to a wide range of insecticides including organophosphates (OPs), carbamates (CBs), synthetic pyrethroids (SPs), cyclodienes, neonicotinoids and insect growth regulators (IGRs) (Cahill et al 1996;Ahmad et al 2002;El Kady & Devine 2003;Horowitz et al 2004;Roditakis et al 2005;Roditakis et al 2006;Roditakis et al 2009;Dennehy et al 2010;Vassiliou et al 2011;Yuan et al 2012). Toxicity of OPs and CBs to animals is attributed to their ability to inhibit the AChE enzyme from breaking down ACh, leading to an increase of both the level and duration of action of the neurotransmitter, ACh (Dulin et al 2012).…”
