“…2), are consistent with decreases in susceptibility observed in the Þeld in Ͻ10 yr in Arizona (Li et al 2003, Dennehy et al 2004) and Israel (Horowitz et al 1999, Horowitz et al 2005). In addition, B. tabaci strains exhibited reduced susceptibility in Ͻ10 yr to other insecticides (Prabhaker et al 1992, Bloch and Wool 1994, Horowitz and Ishaaya 1994, Cahill et al 1996.…”

We used computer simulations to examine evolution of resistance to the insect growth regulator (IGR) pyriproxyfen by the sweetpotato whitefly, Bemisia tabaci (Gennadius), biotype B [=Bemisia argentifolii (Bellows & Perring)]. Consistent with trends seen in cotton (Gossipyium spp.) fields in Arizona and Israel, results suggest that evolution of resistance to pyriproxyfen may occur rapidly in this haplodiploid insect. Similar to results from models of diploid insects, resistance evolved faster with increases in toxin concentration, dominance of resistance in females, the initial frequency of the resistance allele, and the proportion of the region treated with pyriproxyfen. Resistance was delayed by fitness costs associated with resistance. Movement between treated and untreated cotton fields had little effect, probably because untreated cotton leaves provided internal refuges in treated fields and whiteflies were controlled with other insecticides in external refuges. Resistance evolved faster when susceptibility to pyriproxyfen was greater in susceptible males than susceptible females. In contrast, resistance evolved slower when susceptibility to pyriproxyfen was greater in resistant males than resistant females. Results suggest that growers may be able to prolong the usefulness of pyriproxyfen by applying lower toxin concentrations and promoting susceptible populations in refuges.

“…However, despite the extensive literature on the subject, there are relatively few empirical studies that confirm that investment in such adaptations exacts a cost (Minkoff and Wilson, 1992;Carriere et al, 1994Carriere et al, , 1995Yamamoto et al, 1995;Chevillon et al, 1997;Alyokhin and Ferro, 1999;Boivin et al, 2001). Some authors have failed to reveal any detrimental effects of insecticide resistance (Follett et al, 1993;Tang et al, 1997Tang et al, , 1999Baker et al, 1998) and some have shown such organisms to be even more successful than their susceptible counterparts in the absence of insecticides (Omer et al, 1992;Bloch and Wool, 1994;White and Bell, 1995;Mason, 1998;Haubruge and Arnaud, 2001). In other studies, some measures of fitness have been negatively affected, others positively (Brewer and Trumble, 1991) and different strains of insect, exhibiting resistance to the same compound, can show opposite associations (Chevillon et al, 1997;Hollingsworth et al, 1997;Oppert et al, 2000).…”

Analogous pleiotropic effects of insecticide resistance genotypes in peach–potato aphids and houseflies

We show that single-point mutations conferring target-site resistance (kdr) to pyrethroids and DDT in aphids and houseflies, and gene amplification conferring metabolic resistance (carboxylesterase) to organophosphates and carbamates in aphids, can have deleterious pleiotropic effects on fitness. Behavioural studies on peach-potato aphids showed that a reduced response to alarm pheromone was associated with both gene amplification and the kdr target-site mutation. In this species, gene amplification was also associated with a decreased propensity to move from senescing leaves to fresh leaves at low temperature. Housefly genotypes possessing the identical kdr mutation were also shown to exhibit behavioural differences in comparison with susceptible insects. In this species, resistant individuals showed no positional preference along a temperature gradient while susceptible genotypes exhibited a strong preference for warmer temperatures.

“…The increase of resistance in both selected lines, but not in the control line, indicates that fenpropathrin and fenpropathrinϩacephate resistance in B. argentifolii is at least in part genetically determined (Bloch and Wool 1994), and that at least part of the variation in resistance is additive (Falconer 1989).…”

“…Populations found in the Þeld are usually more heterogeneous, and their response to insecticidal pressures more complex and diverse. Field responses would be the result of the interaction of environment, population structure, and selection intensity (Bloch and Wool 1994). The alternation of insecticides and the immigration of susceptible populations from other crops could delay the evolution of resistance in the Þeld.…”

A large, genetically diverse pool of Bemisia argentifolii Bellows & Perring was collected in 1994 from different crops, and a mixed colony was established in the laboratory. Subsets of this colony were reared on cotton plants held in large Plexiglas cages, and adult whiteflies were selected for resistance to fenpropathrin and to fenpropathrin + acephate (1:5). Selection was performed by exposing adults to treated glass vials at doses sufficient to give 60-80% mortality. Thirteen generations of adult selection with fenpropathrin + acephate yielded 856.3- and 1,289.3-fold tolerance (using lethal concentration ratio), respectively, to fenpropathrin and to fenpropathrin + acephate, indicating additive genetic variation for resistance in the source population. Selection with fenpropathrin alone yielded only a 10.9-fold increase in tolerance to fenpropathrin at the end of the selection period. There was no significant change in tolerance to fenpropathrin + acephate in this strain. Contrary to expectations, the early onset and the magnitude of resistance attained on selection with fenpropathrin + acephate compared with fenpropathrin alone indicates that this mixture evidently possesses a high degree of selectivity for development of resistance in B. argentifolii. Estimates of realized heritability of resistance to fenpropathrin and to fenpropathrin + acephate in B. argentifolii (in the fenpropathrin + acephate-selected strain) showed that they were significantly higher in the first half of selection (six generations), in both instances. Rearing of the fenpropathrin + acephate-resistant strain under conditions free of insecticides for six generations did not result in any significant decline in resistance, indicating that resistance is fairly stable.
