“…Kennett (1970) found a fairly high level of resistance to parathion in mites collected from San Joaquin Valley citrus, probably E. tularensis. Tanigoshi and Congdon (1983) also found more resistance to organophosphate insecticides in a San Joaquin Valley population than in a Riverside population of Euseius. Voucher specimens show these populations to be E. tularensis and E. hibisci, respectively.…”

“…A maioria dos fungicidas foi classificada nas classes 1 e 2 (Tabela 3), representando o grupo de agroquímicos que menor efeito adverso causou a I. zuluagai. Resultados semelhantes foram também relatados para outras espécies de ácaros por Croft & Nelson (1972), Samsoe-Petersen (1983), Tanigoshi & Congdon (1983) e Kovaleski & Brehm (não publicado).…”

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).

“…This is concerning for orchard conservation biological control because all current studies on glufosinate suggest it is much more harmful to natural enemies than glyphosate [ 13 , 15 , 28 , 29 ]. Paraquat can also cause substantial mortality in a variety of natural enemies [ 30 , 31 , 32 , 33 ]. Therefore, if glyphosate is phased out, there is potential for a shift to the use of herbicides, such as glufosinate and paraquat, that are disruptive to biological control of mites and other pests.…”

Herbicides Harm Key Orchard Predatory Mites

The phytoseiid mites Galendromus occidentalis and Amblydromella caudiglans are critical for conservation biological control of pest mites in Washington State, U.S.A. apples. While the non-target effects of insecticides on phytoseiids are well described, research on herbicide effects is limited. Using laboratory bioassays, we examined lethal (female mortality) and sublethal (fecundity, egg hatch, larval survival) effects of seven herbicides and five adjuvants on A. caudiglans and G. occidentalis. The effects of mixing herbicides with recommended adjuvants were also tested to determine if the addition of an adjuvant increased herbicide toxicity. Glufosinate was the least selective herbicide tested, causing 100% mortality in both species. Paraquat caused 100% mortality in A. caudiglans and 56% mortality in G. occidentalis. Sublethal effects were significant for both species when exposed to oxyfluorfen. Adjuvants did not cause non-target effects in A. caudiglans. The non-ionic surfactant and methylated seed oil increased mortality and decreased reproduction in G. occidentalis. The high toxicity of glufosinate and paraquat for both predators is concerning; these are the primary “burn down” herbicide alternatives to glyphosate, which is decreasing in use due to consumer toxicity concerns. Field studies are needed to determine the extent to which herbicides disrupt orchard biological control, focusing on glufosinate, paraquat, and oxyfluorfen. Consumer preferences will need to be balanced with natural enemy conservation.
