"Insecticidal potentialities of scorpion root (Aristolochia bracteolata) against the third instar larvae of the khapra beetle (Trogoderma granarium). Organic and water extracts of three parts (fruits, leaves and roots) were tested at three concentrations (1.25%, 2.5% and 5% w/v) in laboratory experiments, during 2010-2011, at the Environment and Natural Resources Research Institute, Sudan. The main parameters considered included, mortality and repellent effects of treatments on the pest, and the consequent impact on sorghum grains damage. The results of bioassay experiment revealed very poor mortality effects by all extracts of scorpion root without significant differences from the untreated control, except the highest dose (5%) of leaves ethyl acetate extract which showed the best significant result, though hardly exceeded 50% mortality after three weeks post treatments. But, the latter extract has attained the next inferior chemical yield compared to the other extracts." [Mokhtar, Mokhtar&Satti, Abdalla. (2012).
