[Cross-resistance between dicofol and other acaricides in Brevipalpus phoenicis (Acari: Tenuipalpidae)]

Abstract: Cross-resistance relationships between dicofol and other acaricides recommended in citrus were evaluated in Brevipalpus phoenicis (Geijskes) to find alternative products for managing dicofol-resistant mites. Susceptible and dicofol-resistant B. phoenicis strains were tested against fenbutatin oxide, propargite, fenpyroximate and bromopropilate. Dicofol-resistant B. phoenicis showed positive cross-resistance to bromopropilate and negative cross-resistance to fenpyroximate. No cross-resistance was detected between dicofol and the acaricides fenbutatin oxide and propargite. Therefore, among the acaricides tested only bromopropilate should be avoided for managing dicofol resistance in B. phoenicis.
