| Resumen en inglés | The susceptibility of Drosophila melanogaster to carbofuran and the use of this organism in biomonitoring residues of the insecticide in cabbage was evaluated. Under the conditions of the bioassay, residues-film bioassay in Petri dish, carbofuran degraded depending on the temperature and time of exposure. Bioassays conducted with D. melanogaster showed that its toxicity increases with temperature (20 to 35 °C). LC50 values, calculated as a function of temperature, ranged from 3.6 to 10.5 mg/g body weight (bw) for males and from 2.9 to 8.7 mg/g bw for females. The formulated product Furadan® G was applied on cabbage (Brassica oleracea, var. capitata) and the residues of carbofuran were determined by bioassay. The determination limit of the bioassay was 0.1 mg/kg and the method presented reproducibility with coefficient variation of 17 %. The validation of the bioassay by high performance liquid chromatography confirms the viability of the bioassay with D. melanogaster in monitoring the residues of carbofuran in cabbage |
