Seletividade De Chlorfenapyr E Fenbutatin-Oxide Sobre Duas Espécies De Ácaros Predadores (Acari: Phytoseiidae) Em Citros

Abstract: Com o uso de bioensaios, verificaram-se os efeitos residual de contato, ovicida e de persistência dos produtos chlorfenapyr e fenbutatin-oxide sobre duas espécies de ácaros predadores, Iphiseiodes zuluagai Denmark & Muma e Euseius alatus DeLeon (Acari: Phytoseiidae), associados ao ácaro da leprose-dos-citros Brevipalpus phoenicis (Geijskes) (Acari: Tenuipalpidae). O efeito total sobre os adultos foi estudado por meio do método residual de contato com pulverização em superfície de vidro, conforme metodologi… Show more

“…Such results were expected since it follows previous reports of low impact of fenbutatin oxide at the recommended concentrations on mortality of the phytoseiids Typhlodromus pyri Scheuten, Amblyseius andersoni (Chant), A. bibens (Blommers) and I. zuluagai (Overmeer and van Zon 1981;Reis et al 1998b;Reis and Souza 2001). In contrast, fenbutatin oxide was reported as slightly harmful to Euseius alatus (De Leon) (Acari: Phytoseiidae) and sulfur was reported as moderately noxious to I. zuluagai based on similar studies (Reis et al 1998b;Reis and Souza 2001).…”

“…Sulfur and fenbutatin oxide, are commonly recommended for its control Andrei 1999), but their selectivity to predatory mites, such as Iphiseiodes zuluagai Denmark and Muma (Acari: Phytoseiidae) Reis et al , 1998a, is based only on acute lethal assessments (Reis et al 1998b;Reis and Souza 2001). The aim of this study is to provide a more robust population-level assessment of the selectivity of these compounds to the Brazilian coffee pest O. ilicis and its predator I. zuluagai.…”
