Abstract
Studies on the management of pulse bruchid, C analis (Fabricius) (Coleoptera: Bruchidae) under modified atmospheric condition was undertaken at the College of Agriculture, Raichur, Karnataka during 2010-11. Change in gas concentration was measured and there was gradual depletion of O2 and increase of CO2. This was mainly due to respiration of insects and grains during storage. There was no change in O2 and CO2 gas concentration where there was no O2 hence there was no scope for insects as well as grains for respiration. The CO2 concentrations of 15 and 20 per cent exposed for 45 days gave cent per cent mortality of insects wherein, no adults survived at that concentration. Further, there was no adult emergence thereby egg lying and mass loss (%) was also nil
