VENOM’S YIELD AND VENOM’S PROPERTIES OF EASTERN STEPPE VIPER VIPERA RENARDI AT DIFFERENT TIMES OF ITS SEASONAL ACTIVITY

The venom yield of the eastern steppe viper Vipera renardi (Christoph, 1861) was shown to be higher in the summer than in the spring and autumn. No seasonal variability of the venom toxicity (the average lethal dose DL50 for banana crickets Gryllus locorojo Weissman et Gray, 2012) and the enzyme activities therein (proteases and L-amino acid oxidase) was detected.
