“…This type of reduced penetration–based resistance has been observed in organophosphate‐resistant strains of Culex quinquefasciatus (Stone & Brown, 1969) and Culex tarsalis (Apperson & Georgiou, 1975). Resistance caused by cuticular changes is not specific for a certain class of insecticides (Golenda & Forgash, 1989; Noppun et al ., 1989; Lin et al ., 1993). Therefore, it is possible that the low level of cross resistance to many insecticides observed in the An.…”

A large scale microarray (20k MMC1) from the African malaria vector Anopheles gambiae was used to monitor gene expression in insecticide resistant and susceptible strains of the Asian mosquito Anopheles stephensi. Heterologous hybridization at slightly reduced stringency yielded approximately 7000 significant signals. Thirty-six putative genes were differentially transcribed between the pyrethroid-resistant (DUB-R) and the susceptible (BEECH) strains. The expression profiles of selected transcripts were verified by real-time PCR. A gene putatively involved in the thickening of the adult cuticle showed the most striking up-regulation in DUB-R. A more specialized microarray containing 231 An. gambiae genes putatively involved in insecticide detoxification was used to further analyse classical insecticide resistance genes. Three glutathione S-transferase (GST) transcripts, one esterase and a cytochrome P450 were up-regulated in the resistant strain, while two peroxidases were down-regulated.

“…Penetration resistance in ticks could arise through alterations in the ability of an acaricide to penetrate or otherwise enter an individual that is treated with acaricide. Although this resistance mechanism has been identified in a few arthropods (NOPPUN et al, 1989), including R. (B.)…”

Acaricide resistance has become widespread in countries where cattle ticks, Rhipicephalus (Boophilus) microplus, are a problem. Resistance arises through genetic changes in a cattle tick population that causes modifications to the target site, increased metabolism or sequestration of the acaricide, or reduced ability of the acaricide to penetrate through the outer protective layers of the tick's body. We review the molecular and biochemical mechanisms of acaricide resistance that have been shown to be functional in R. (B.) microplus. From a mechanistic point of view, resistance to pyrethroids has been characterized to a greater degree than any other acaricide class. Although a great deal of research has gone into discovery of the mechanisms that cause organophosphate resistance, very little is defined at the molecular level and organophosphate resistance seems to be maintained through a complex and multifactorial process. The resistance mechanisms for other acaricides are less well understood. The target sites of fipronil and the macrocyclic lactones are known and resistance mechanism studies are in the early stages. The target site of amitraz has not been definitively identified and this is hampering mechanistic studies on this acaricide.Keywords: Cattle tick, resistance mechanisms, target site mutation, metabolism. ResumoA resistência aos acaricidas tornou-se amplamente difundida nos países onde os carrapatos bovinos, Rhipicephalus (Boophilus) microplus, são um problema. A resistência surge por meio de alterações genéticas em uma população de carrapatos que causam modificações no local de ação, aumento do metabolismo ou sequestro do acaricida, ou ainda redução na capacidade do acaricida em penetrar através das camadas protetoras do corpo do carrapato. Neste artigo, foram revisados os mecanismos moleculares e bioquímicos da resistência aos acaricidas que ocorrem em R. (B.) microplus. A partir de um ponto de vista dos mecanismos envolvidos, a resistência aos piretróides tem sido caracterizada em maior grau do que em qualquer outra classe de acaricida. Embora uma grande quantidade de pesquisas têm sido direcionada para a descoberta de mecanismos que causam resistência aos organofosforados, muito pouco é conhecido ao nível molecular, e essa resistência parece ser mantida por intermédio de um processo multifatorial e complexo. Os mecanismos de resistência para os demais acaricidas são bem menos compreendidos. Os alvos de ação do fipronil e das lactonas macrocíclicas são conhecidos, e os estudos dos mecanismos de ação envolvidos estão ainda em estágios iniciais. O alvo de ação do amitraz ainda não foi definitivamente identificado, e isso é limitante aos estudos dos mecanismos envolvidos na resistência a esse acaricida.Palavras-chave: Carrapato bovino, mecanismos de resistência, mutação no local de ação, metabolismo.

“…The resistance of P. xylostella to insecticides is primarily a function of increased activity of metabolic enzymes , decreased cuticular penetration (Noppun et al 1989), insensitivity of the target site (Konno and Shishido 1994), decreased nerve sensitivity, and knockdown resistance (Hama et al 1987;Kwon et al 2004). …”
