Abstract

Amblyseius swirskii (Athias-Henriot) is a polyphagous predatory mite which feeds on pollen and small arthropod preys like whiteflies, thrips and mites. This species is widely used in IPM programs in greenhouses, being essential for its success, to obtain information about the non target effects of the pesticides currently used in those crops where the mite is artificially released. This work describes a laboratory contact residual test for evaluating lethal (mortality after 72 hour exposure to fresh residues) and sublethal effects (fecundity and fertility of the surviving mites) of eleven modern pesticides to adults of A. swirskii. Spiromesifen is lipogenesis inhibitor; flonicamid a selective feeding inhibitor with a mode of action not totally known; flubendiamide a modulator of the rhyanodin receptor, sulfoxaflor has a complex mode of action not totally ascertained; metaflumizone is a voltage dependent sodium channel blocker; methoxyfenozide is an IGR, spirotetramat inhibits lipids; abamectin and emamectin activate the Cl- channel; spinosad is a neurotix naturalyte and deltamethrin a pyrethroid used as positive standard. Selected pesticides are effective against different key pests present in horticultural crop areas and were always applied at the maximum field recommended concentration in Spain if registered, or at the concentration recommended by the supplier. Out of the tested pesticides, spiromesifen, flonicamid, flubendiamide, sulfoxaflor, metaflumizone, methoxyfenozide and spirotetramat were harmless to adults of the predatory mite (IOBC toxicity class 1). The rest of pesticides exhibited some negative effects: emamectin was slightly harmful (IOBC 2), deltamethrin moderately harmful (IOBC 3) and spinosad and abamectin harmful (IOBC 4). Further testing under more realistic conditions is needed for those pesticides having some harmful effect on the mite prior deciding their joint use or not. Key words: Amblyseius swirskii, adults, laboratory, residual test, spiromesifen, flonicamid, flubendiamide, sulfoxaflor, metaflumizone, methoxyfenozide, spirotetramat, emamectin, deltamethrin, abamectin, spinosad.
