Resistencia deTetranychus urticaeKoch a Acaricidas Usados en la Producción de Rosal de Invernadero en México

Resistencia de cuatro poblaciones del acaro (Tetranychus urticae Koch.) a propargite en rosa de corte (Rosa x hybrida) en el Estado de México, México

“…These results agree with those obtained by Villegas-Elizalde et al (2009), who found values RR 50 and 95 of 1.3 and 0.4X respectively. The results differ from those reported by Aguilar-Medel et al (2011) who estimated that, RR 50 and RR 95 were 17.5 and 365296.2X, respectively.…”

Contrasting roles of cytochrome P450s in amitraz and chlorfenapyr resistance in the crop pest Tetranychus urticae

“…urticae strains (Aguilar-Medel et al, 2011;AI-Antary et al, 2012;Herron and Rophail, 2003;Simma et al, 2020;Van Leeuwen et al, 2005, 2004. This observation raises the question of whether a "hitchhiking effect" is at play, wherein two closely linked pesticide resistance genes under one acaricide pressure are simultaneously favored (Kojima and Schaffer, 1967;Smith and Haigh, 1974), or if a single evolved gene provides resistance to more than one molecule (Duarte et al, 2022).…”

Resistance to Abamectin in Field Population of Tetranychus urticae Koch (Acari: Tetranychidae) Associated with Cut Rose from State of Mexico, Mexico

“…For this reason, it was used often. In 2009, T. urticae populations in this region were collected, and high levels of resistance to abamectin were documented (Aguilar-Medel et al 2011). However, the growers increased the doses to reestablish the original level of control, leading gradually to higher levels of acaricide resistance, and then to larger numbers of cases of field-efficacy failures.…”

“…The indicated biotic potential of T. urticae expressed in its short life cycle and high reproductive rate, together with factors such as the high use rate of acaricides and low migration in greenhouses (Croft & Van de Baan 1988;Van Leeuwen et al 2010), contribute to making the problem more severe in this type of production system (Ferreira et al 2015). Aguilar-Medel et al (2011) have documented the response of twospotted spider mite populations to abamectin in this region, and suggest that the problem has become acute because of increasing dosages, and possibly to shortened intervals of application and scarce rotation of acaricides with different modes of action. Among the recommendations for minimizing the level of resistance, exclusion of abamectin from T. urticae management programs is proposed for sites where control failures have been observed.…”
