Abstract
The present study was conducted to find out the effectiveness of venom extracted from Hottentotta tamulus (Scorpiones: Buthidae) against Rhopalosiphum erysimi (Hemiptera: Aphididae) in the laboratory. R. erysimi were treated orally as well as topically with different concentrations of the crude venom. All aphids died within 6 hr with oral
treatment at 1.5µl of the venom dose. However, at the same venom dose, 100% mortality was achieved at 8 hr posttreatment when applied topically. Similarly, oral administration of 1µl and 0.5µl venom caused 100% mortality at 8 hr post-treatment compared to 10 hr and 12 hr post-treatment of topical application, respectively. It is concluded that
oral treatment of venom was more efficient compared to its topical treatment with same doses of treatment.
