Abstract

The studies on the effect of smoke on mortality of stored pulses against pulse beetle, Callosobruchus chinensis (L.) were carried out to know the impact of different smokes on percent mortality of the pest of treated pulse seeds. The pulses used in this experiment was green gram, black gram and red gram. The experiments conducted on the effect of smoke generated by burning plant and animal origin by-products on mortality of adults of C. chinensis at 1, 12, 24, 48, 72, 96 and 120 h exposure to smoke under airtight conditions resulted in 50.98 percent after 120h of exposure to mustard seed cake followed by karanj seed cake (50.59), cow dung cake (37.15), neem seed cake (33.26) and wheat husk smoke (28.43). Therefore, present laboratory studies clearly showed that plant and animal origin by-products smoke were found quite effective against pulse beetle, C. chinensis without causing any deleterious effect on quality parameters of pulse seeds. These botanical products which were used as smo

Conclusion

The results obtained during this course of investigation showed that smoke generated from burnt mustard seed cake has potential to protect pulse commodities viz., green gram, black gram and red gram grains against pulse beetle C. chinensis at 120h exposure to smokes. It was followed by neem seed cake and Karanj seed cake smokes. Further, it has also been concluded that smokes were more effective during the initial stages of insect growth. It has also been concluded that among all the plant and animal origin by-products, smoke from mustard seed cake was found to be the most effective on adult mortality of pulse beetle. As being natural, easily available, eco- friendly, cost effective and easy to adopt by small scale farmers, these plant and animal origin by-products can therefore be used as safe alternatives to synthetic insecticides and conventional harmful fumigants under storage conditions. In future course of time, using smoke derived from various plant and animal origin products ca
