Abstract:
In this study we have investigated hemolytic, edematogenic and neurotoxic effects of the crude venoms of three Polybia species; P. occidentalis, P. paulista and P. ignobilis. In addition, protein contents and dry weights of these wasp`s venom reservoirs have also been compared. P. ignobilis presented the highest protein content and highest dry weight per venom reservoir. When injected in the hind paw of rats relatively to the other two, it evoked a stronger edematogenic effect. The venom of P. paulista showed the most potent hemolytic activity on human washed red blood cells. When tested on the erythrocytes of different species (rat, pigeon, ox, sheep, snake and horse), the three venoms showed marked differences in hemolytic activity according to the blood species. However, this variability appeared to be similar for the three venoms. Moreover, the intracerebroventricular injection of each of all three venoms caused tonic clonic seizures and death to rats. Present data suggest that although the three species are closely phylogenetic related, there must be pharmacological differences among the venom compounds that should be better investigated.
