Methomyl is a carbamate acetylcholinesterase inhibitor that acts by contact and systemically and is one of the agrochemicals of mayor use as insecticide-acaricide to control a broad spectrum of agricultural pests. Peru lacks information regarding hematological aspects of bony fishes which could be used as potential physiological biomarkers of sub lethal responses in ecotoxicological bioassays. Aims of the current research were: 1) evaluate acute toxicological effect of methomyl on an ornamental Amazonian fish Corydoras arcuatus Elwin, 1939 (Callichthyidae) at 2, 4, 6, 8, 24 and 48 h exposure, and 2) characterize leukocytes of C. arcuatus, Corydoras leucomelas Eigenmann & Allen, 1972 and Corydoras leopardus Myers, 1933, and determinate quantitative reference values. Bioassays with methomyl were performed on plastic pots of 1000 mL. Values of LC50 (mg AI L -1 ) were 10.84; 3.18; 0.28; 0.01; 0.002 and monocytes (18.4%)> neutrophiles (8.2%)> eosinophiles (5.2%)> basophiles (3.2%). Blood parameters obtained contribute to the knowledge of this genus and could be potentially employed as biomarkers of sublethal responses in ecotoxicological bioassays.
