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. The cured turmeric rhizomes were observed after 3, 6 and 9 months of treatment for each concentrations of CO2 by using destructive sampling method and the data on fecundity, adult emergence and weight loss due to damage were recorded. The results revealed that exposing the cured turmeric rhizomes to 50 to 80 per cent CO2 not only checked cigarette beetle infestation but also prevented the progeny development up to nine months of treatment.
