ATIVIDADE REPELENTE E AÇÃO ANTIMICROBIANA DE PEÇONHA DE Dinoponera quadriceps (Hymenoptera: Formicidae)

: Ant venom has been investigated as a potential source of peptides with high antimicrobial activity. capillary tube. This tube was placed in contact with distilled water and the extracted substance was impregnated in filter paper. The bioassays were carried out in 500 mL beakers, 10 for each of the two techniques. Both venom extraction techniques were repeated 10 times, for each bioassay, as well as the 10 workers of A. sexdens were collected individually for each experiment and discarded later. Subsequently, the workers' behavior was assessed. For the evaluation of antimicrobial activity, the disk diffusion method was used, based on the inhibition halo against Staphylococcus aureus , Micrococcus luteus , Bacillus subtilis , Escherichia coli and Pseudomonas aeruginosa bacteria. The tests did not reveal any repellent action or antibacterial activity for the D. quadriceps venom.
