| Abstract | ||
| Different concentrations of CO2 were tested as curative control method against the the saw-toothed beetle, Oryzaephilus saurinamensis and the warehouse moths, Ephestia Spp. which attack the dry date fruits during storage. The mortality percentages positively correlated with CO2 concentration and the exposure period. Treatment with 20% CO2 (lowest concentration) for 1 day exposure gave 35.3% mortality of O. saurinamensis but only 16.9 and 26.6% mortality of Ephestia Spp.larvae and pupae, respectively. 98.9% mortality of O. saurinamensis was obtained with 50% CO2 (highest concentration) for 7 days, while the same treatment gave 93.3% and 90.3%. mortality of Ephestia Spp.larvae and pupae, respectively. | ||
