Abstract

The efficacy of Taramira (Brassica juncea) oil, leaf powder and seed powder was tested against chickpea beetle (Callosobruchus chinensis L.) attacking stored chickpeas (Cicer arietinum). The taramira oil was applied at 0.125, 0.25, 0.5 and 1.0 mL/40 g of chickpea grains. Similar concentrations were applied in case of taramira leaf and seed powder. Observations were taken on the number of holes per grain of chickpea made by C. chinensis, number of eggs laid per grain, adult emergence from 10 egg laid grains and percent weight loss. It was concluded that the effect of taramira oil was significantly different from the control at all the concentrations applied. Best results were obtained by 1.0 mL of oil/40 g of chickpea grains. The 0.5 and 0.25 mL/40 g of grains also gave good results. Insect control was moderate at 0.125 mL/40 g of grains. Similar results were observed from leaf and seed powder. From the results it could be concluded that taramira could play an important role in the management of this pest.
