“…Various concentrations of permethrin were generated in acetone through serial Brazil (Barros et al, 2002;Guerrero & Barros, 2006). Various resistance mitigation strategies, such as insecticide mixtures, synergists, or rotation with different classes of insecticides have been attempted to resolve problems of resistance to pyrethroids in horn flies (Byford et al, 1987;Sparks & Byford, 1988;Mckenzie & Byford, 1993;Guglielmone et al, 1999;Oremus et al, 2006).…”

Dynamics and mechanisms of permethrin resistance in a field population of the horn fly, Haematobia irritans irritans Abstract A study was conducted at the Pressler ranch, near Kerrville, Texas, USA between 2002 and 2006 to determine the dynamics and mechanisms of resistance to permethrin in a field population of the horn fly, Haematobia irritans irritans (L.). Changes of resistance to pyrethroid insecticide associated with use of a pour-on formulation of cyfluthrin in 2002 and use of diazinon ear tags in subsequent years were studied using a filter paper bioassay technique and a polymerase chain reaction assay that detects two sodium channel mutations, kdr and super-kdr resistance alleles. A maximum of 294-fold resistance to permethrin was observed in the summer of 2002. A significant decrease in the resistance level was observed in spring 2003, and resistance continued to decline after animals were treated with diazinon ear tags. In response to pyrethroid treatments, the allelic kdr and super-kdr frequency increased from 56.3% to 93.8% and from 7.5% to 43.8%, respectively in 2002, and decreased significantly in 2003 when the pyrethroid insecticide was no longer used to treat animals. Females were found to have a higher allelic super-kdr frequency than males in 2002, while no difference was detected between males and females in the allelic kdr frequency. There was a significant positive correlation between frequencies of the sodium channel mutations and levels of permethrin resistance, suggesting that the sodium channel mutations, kdr and super-kdr, are the major mechanisms of resistance to pyrethroids in this horn fly population. Results of synergist bioassays also indicated possible contributions of two metabolic detoxification mechanisms, the mixed function oxidases (MFO) and glutathione S-transferases (GST). Compared to a horn fly infestation of an untreated herd, treatments with the pyrethroid pour-on formulation failed to control horn flies at the Pressler ranch in 2002. Sustained control of horn flies was achieved with the use of diazinon ear tags in 2003 and subsequent years.

“…The feasibility of using two insecticides in rotation, mixture, or sequentially for résistance management has been examined in several laboratories by means of cage experiments (Cilek and Knapp 1993;Curtis et al 1993;Georghiou et al 1983;McKenzie and Byford 1993). As expected, the use of différent insecticides and différent species of insects has led to divergent conclusions.…”

La demande pour des stratégies efficaces de gestion de la résistance se fait de plus en plus pressante, au fur et à mesure que le nombre d'espèces résistantes aux insecticides augmente mondialement alors que les ressources insecticides diminuent. Les perspectives de développement de telles stratégies sont accrues par les développements récents en biochimie, en génétique moléculaire, en écologie, en dynamique, en dépistage et dans d'autres aspects importants de la résistance. Les approches généralement reconnues pour la gestion de la résistance sont regroupées en trois catégories principales: une pression de sélection faible, complétée par une composante élevée de mesures non-chimiques (gestion par modération); l'élimination de l'avantage sélectif des individus résistants en augmentant l'absorption des insecticides par l'utilisation d'attractifs, ou en supprimant les enzymes de detoxication par l'utilisation de synergistes (gestion par saturation); l'application d'une sélection multi-directionnelle au moyen de mélanges ou de rotations d'insecticides non-apparentés ou par l'utilisation d'insecticides à plusieurs sites d'action (gestion par attaque multiple). Ces approches ne sont pas mutuellement exclusives et des éléments de chacune peuvent être utilisés pour la formulation d'un programme saisonnier de gestion. La stratégie choisie doit être basée sur une connaissance approfondie des effets sur la résistance des insecticides envisagés, et de la biologie et de l'écologie des espèces concernées, et elle doit utiliser toutes les méthodes de lutte non-chimiques disponibles.The need for effective strategies in resistance management is becoming more pressing as the number of insecticide-resistant species continues to increase worldwide while insecticide resources are diminishing. Prospects for development of such strategies are enhanced by recent advances in knowledge on the biochemistry, molecular genetics, ecology, dynamics, monitoring, and other important aspects of resistance. The generally recognized approaches to resistance management are grouped under three principal categories: first, low selection pressure, supplemented by a strong component of non-chemical measures (management by moderation); second, elimination of the selective advantage of resistant individuals by increasing insecticide uptake through the use of attractants, or by suppressing of detoxication enzymes through the use of synergists (management by saturation); and third, application of multi-directional selection by means of mixtures or rotations of unrelated insecticides or by use of chemicals with multi-site action (management by multiple attack). These approaches are not mutually exclusive and elements from each can be used to formulate a season-long management program. The strategy chosen must be based on a thorough knowledge of the resistance implications of the candidate insecticides and of the biology and ecology of the species concerned, and must make use of all available non-chemical control measures

“…In order to slow development of resistance, biennial or triennial alternation of pyrethroids and organophosphates or use of insecticide mixtures has been proposed. This approach is supported by observations that cross-resistance does not develop between pyrethroids and organophosphates (Sheppard and Joyce 1992) and that sensitivity to organophosphates, such as diazinon, may increase as resistance develops to pyrethroids (Mckenzie and Byford 1993).…”

Danielson, T. J. and Golsteyn, L. R. 1997. Weight gain and feed utilization in Hereford steers exposed to diazinon. Can. J. Anim. Sci. 77: 181-183. Body weights and feed consumption were monitored in 48 Hereford steers, under feedlot conditions, for 10 wk after exposure to diazinon, an organophosphate insecticide. Experimental design consisted of four complete blocks, each of four treatment groups (positive and negative controls, two insecticidal ear tags and four insecticidal ear tags). Plasma cholinesterase activity was reduced by 50%, 24 h after topical application of diazinon directly to the skin (positive control) but was not reduced after attachment of either two or four insecticidal ear tags per animal. Daily weight gain and feed utilization in control animals, during the 70-d study, were 1.21 ± 0.22 kg d -1 and 0.144 ± 0.007 kg kg -1 (dry matter basis) and were not altered in steers exposed to diazinon.
