          Abstract

          Testes de efeito adverso de agroquímicos sobre Iphiseiodes zuluagai Denmark & Muma (Acari: Phytoseiidae) foram conduzidos em laboratório, utilizando o método residual de contato com pulverização em superfície de vidro. Foram testados 42 produtos químicos, a maioria utilizada na citricultura brasileira. A mortalidade e o efeito dos produtos na reprodução do ácaro foram avaliados diariamente durante oito dias. Os produtos foram classificados quanto ao efeito total causado ao ácaro (combinação da mortalidade e efeito na reprodução) em quatro classes de toxicidade propostas pela IOBC/WPRS. Os resultados mostraram que cerca de 26% dos produtos testados foram inócuos (captan, clofentezine, fenbutatin oxide, fosetyl, hexythiazox, hidróxido de cobre, naled, oxicloreto de cobre, óxido cuproso e tetradifon), 14% levemente nocivos (abamectin, chlorothalonil, sulfato de cobre, thiophanate-methyl (PM) e ziram), 7% moderadamente nocivos (enxofre, parathion-methyl e thiophanate-methyl (SC)) e 52% nocivos ao ácaro (acrinathrin, amitraz, azinphos-ethyl, azocyclotin, benomyl, bifenthrin, bromopropylate, carbaryl, carbosulfan, chlorfenapyr, cyhexatin, dicofol, fenpropathrin, fenpyroximate, mancozeb, óleo mineral e vegetal, phosmet, propargite, quinomethionate, triazophos, e vamidothion).

          Translated abstract

          The side-effects of agrochemical to Iphiseiodes zuluagai Denmark & Muma (Acari: Phytoseiidae) were studied in laboratory using the residual contact spray method in glass surface. Forty-two plant protection products, used in Brazilian citrus orchards, were tested. Mite mortality and fecundity were evaluated for eight days. Tested products were ranked in toxicity classes, according to IOBC/WPRS system, by the total effect (combination of mortality and reproduction effect). The results showed that ca. 26% of the tested products were harmless (captan, clofentezine, fenbutatin oxide, fosetyl, hexythiazox, copper hydroxide, naled, copper oxychloride, cuprous oxide and tetradifon), 14% slightly harmful (abamectin, chlorothalonil, copper sulphate, thiophanate-methyl (PM) and ziram), 7% moderately harmful (sulfur, parathion-methyl and thiophanate-methyl (SC)) and 52% harmful to the mite (acrinathrin, amitraz, azinphos-ethyl, azocyclotin, benomyl, bifenthrin, bromopropylate, carbaryl, carbosulfan, chlorfenapyr, cyhexatin, dicofol, fenpropathrin, fenpyroximate, mancozeb, mineral and vegetable oils, phosmet, propargite, quinomethionate, triazophos and vamidothion).
