A variety of toxin proteins have been used against insect pests of economic importance having rare success to control the targeted pests. Scorpion venoms are complex mixtures of toxic peptides that are target specific against wide range of crop pests. Present study was aimed to evaluate insecticidal potential of peptide fractions (3–5KD) obtained from Odontobuthus odonturus (Arachnida: Buthidae) venom. The peptides were used against fruit flies, Bactrocera zonata (Diptera: Tephritidae) in controlled conditions. Topical treatment of different concentrations was done on the dorsal part of flies. Calculated LD50 and LD95were 6.53 μl and 18.84 μl respectively. Significantly higher mortalities were recorded in the treated groups. Findings suggested that low molecular peptide fractions are effective toxin against B. zonata. These peptides if formulated commercially could be the alternative to hard chemistries.
