Experiments were conducted in the biology laboratory of the Department of Entomology, Gomal University, Dera Ismail Khan during 2015 to investigate the efficacy of six different botanicals (Neem, Bakain, Dharek, Turmeric, Tumha and AK), each at six different concentrations (0.5, 1.0, 1.5, 2.0, 2.5 and 3%) for the management of C. chinensis. Fifty gram of sterilized Mung bean grains were treated with these selected plant powders at six different concentrations viz. 3.0, 2.5, 2.0, 1.5, 1.0, 0.5% and data was recorded after 24, 48, 72 hours and 7 days of exposure period. Neem and Turmeric were found to be more effective in all concentrations against pulse beetle as they showed more toxicity against the tested pest. The Neem and Turmeric powders were found comparatively more effective in controlling progeny production of C. chinensis than other tested plant powders. So, it is concluded from the present findings that Neem and Turmeric powders should be incorporated into grain protection practices.
