Residual toxicity of acaricides to Galendromus occidentalis and Phytoseiulus persimilis reproductive potential

摘要: Abstract Understanding the effects of pesticide residues on leaf surfaces through time phytoseiid mites is important to their successful integration into augmentation and/or conservation programs. The residual toxicities fenpyroximate (Fujimite ® ), acequinocyl (Kanemite etoxazole (Zeal spiromesifen (Oberon bifenazate (Acramite ) and abamectin (Agri-mek leaflets Galendromus occidentalis (Nesbitt) Phytoseiulus persimilis Athias-Henriot (Acari:Phytoseiidae) were assessed 3, 6, 10, 14, 17, 24, 30 37 days post treatment. Impacts mortality, fecundity fertility determined following 3 exposure each surface residue interval.
