“…The GST system may account for resistance as a minor pathway, possibly through epistatic interactions with MFOs that contribute to the enhanced metabolization of the chemical (see Raymond et al, 1989). However, GSTbased resistance to organophosphates has been shown to involve high fitness costs in the housefly (Roush and Plapp, 1982), which suggests that the magnitude of the fitness costs associated with the acquisition of metabolic resistance might depend on the ratio of expression (relative to the susceptible reference) of the selected pathway.…”

Adaptive changes in populations encountering a new environment are often constrained by deleterious pleiotropic interactions with ancestral physiological functions. Evolutionary responses of populations can thus be limited by natural selection under fluctuating environmental conditions, if the adaptive mutations are associated with pleiotropic fitness costs. In this context, we have followed the evolution of the frequencies of insecticide-resistant mutants of Cydia pomonella when reintroduced into an untreated environment. The novel set of selective forces after removal of insecticide pressure led to the decline of the frequencies of resistant phenotypes over time, suggesting that the insecticideadapted genetic variants were selected against the absence of insecticide (with a selective coefficient estimated at 0.11). The selective coefficients were also estimated for both the major cytochrome P450-dependent monooxygenase (MFO) and the minor glutathione S-transferase (GST) systems (0.17 and negligible, respectively), which have been previously shown to be involved in resistance. The involvement of metabolic systems acting both through xenobiotic detoxification and biosynthetic pathways of endogenous compounds may be central to explaining the deleterious physiological consequences resulting from pleiotropy of adaptive changes. The estimation of the magnitude of the fitness cost associated with insecticide resistance in C. pomonella suggests that resistance management strategies exclusively based on insecticide alternations would be unlikely to delay such a selection process.

“…Their study indicates that house ßy dispersal is considerable, even when habitats seem ideal. Methoxychlor and stirofos resistance may have been retained in the house ßy populations as a result of lack of biotic potential disadvantages associated with resistance (Roush and Plapp 1982). However, insecticide resistance may not necessarily be associated with application exposure at the feedlots, but rather the result of migration of resistant house ßies into these areas: house ßies are more intensely ex-posed to chemical treatments in domestic settings, and resistant individuals may move to feedlot areas.…”

“…La exposición previa o la expresión de genes de resistencia puede no afectar (Fournier et al 1988, Haubruge & Arnaud 2001, aumentar (James & Price 2002) o disminuir (Ako et al 2004) la aptitud biológica. En algunos casos, los individuos homocigotos susceptibles y los heterocigotos no presentan diferencias en la aptitud biológica entre ellos (Ferrari & Georghiou, 1981 Roush & Plapp 1982, Argentine et al 1989. Carrière et al (2001) encontraron que en dos poblaciones de gusano rosado, Pectinophora gossypiella (Saunders), resistentes a la toxina Cry1Ac de Bacillus thuringiensis (Bt), la supervivencia se redujo 51,5% en promedio respecto a las poblaciones susceptibles.…”

-In two fi eld-collected populations of de Bemisia tabaci (Gennadius) B biotype previously selected with the neonicotinoid insecticide thiamethoxam (NEO-R, NEO-N), and a population susceptible to insecticides (SUSC), the level of response to the insecticide thiametoxam, as well as the life and fertility tables were determined. At LC 95 , the NEO-R population showed a resistance ratio (RR 95 ) value of 8.8-fold, an intrinsic rate of increase (r m ) of 0.72. The fi tness of the NEO-R and NEO-N populations in relation to the SUSC was 1.5 and 2.0, respectively. The RR 95 value for NEO-N was 1.9-fold; it´s r m value was 0.082, while in the SUSC population was 0.041. The developmental time of egg and adult were longer in NEO-R population, while the nymph and pupa lasted longer in the NEO-N and SUSC populations. The developmental time was different in the three NEO-R, NEO-N, and SUSC populations with 19.7 d (315.84 degree days or dd), 15.7 d (250.4 dd) and 18.5 d (296.6 d), respectively. The populations previously selected with thiamethoxam did not reproduce faster than their susceptible counterpart.
