Modified atmosphere with effect of elevated levels of CO2 against cigarette beetle (Lasioderma serricorne Fabricius) in cured turmeric rhizomes (Curcuma longa Linnaeus) during storage

An experiment was conducted to study the effect of elevated levels of CO2 by exposing the artificially infested cigarette beetle in cured turmeric rhizomes to eight different concentrations of CO2 viz., 10, 20, 30, 40, 50, 60, 70 and 80 per cent with three replications of each treatment and the efficacy of treatments was tested based on cured turmeric rhizomes infestation and population buildup of L. serricorne.
