Resistência de Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae) a acaricidas inibidores da respiração celular em citros: resistência cruzada e custo adaptativo

Abstract: -Acaricides that inhibit cellular respiration play an important role in the control of Brevipalpus phoenicis (Geijskes) in citrus groves in Brazil. Studies were conducted to evaluate: (a) the variability in the susceptibility among B. phoenicis populations collected from citrus groves to cyhexatin, azocyclotin, propargite and sulphur; (b) cross-resistance relationships between propargite and azocyclotin, cyhexatin, dinocap, pyridaben and sulphur; and (c) the fitness cost associated with propargite resistance i… Show more

“…Applied in the cultivation of citrus and ornamental plants to control phytophagous mites. Its residues can contaminate water due to agricultural runoff [62], but in the aquatic environment, hydrolysis is around 13 days. It has high potential for bioconcentration and high toxicity for mammals and fish (PPDB, 2009).…”

“…8 Currently B. phoenicis suffers a selective pressure caused by the most commonly used acaricides on citrus crop protection such as dicofol, 9,10 hexythiazox, 11 and propargite. 12 In addition to this pressure, B. phoenicis shows parthenogenetic development leading to a quick promotion of the appearance of an evolved and chemical-resistant type of mite.…”

“…Na citricultura, a alta pressão de seleção exercida por acaricidas e, principalmente, o modo de reprodução do tipo partenogênese telítoca de B. phoenicis são apontados como os principais fatores responsáveis pela rápida evolução da resistência (HELLE et al, 1980;OMOTO, 1998). Casos de evolução da resistência de B. phoenicis já foram detectados para os principais acaricidas utilizados na cultura dos citros, tais como dicofol (OMOTO et al, 2000), hexythiazox (CAMPOS; OMOTO, 2002) e propargite (FRANCO et al, 2007).…”

“…Além da calda sulfocálcica, o enxofre tem sido bastante utilizado para o controle do ácaro-da-falsaferrugem, Phyllocoptruta oleivora (Ashmead), tanto em pomares de citros com sistema manejo orgânico como convencional, o que poderia favorecer a evolução da resistência de B. phoenicis à calda sulfocálcica, devido à possibilidade de resistência cruzada com enxofre, além de outros acaricidas convencionais que apresentam enxofre na molécula e atuam na respiração celular, tais como propargite. A resistência cruzada entre propargite e enxofre em B. phoenicis já foi reportada por Franco et al (2007).…”
