Further studies on the selection of alternatives Methyl bromide suitable for sterilization datesύ

Infestation by pests of stored dates is one of the basic problems in production and maintenance. The Sawtoothed beetle Oryzaephilus surinamensis (L.) is important pest of stored dates in the world that not only allows but also other crops are damaged. One of the most important methods of pest control is using chemicals fumigation. Methyl bromide has been deleted in many developed countries. Biological and physical methods to control the proper procedures are acceptable. The Sawtoothed beetle having proper application of environmental and economic conditions have been adapted to local circumstances and the quality treated dates does not change. In this study, the effects controller formulations of the fungus Beauveria bassiana during storage, the effect of plant compounds in mass numbers to date modern methods of microbial control and effective method combined with modified atmosphere (Combined CO2 + O2) and (Combined N2 + O2) in pest control Sawtoothed beetle storage were examined on Sayer cultivar of dates in terms of packaging. The results showed that the treatment of microbial control about 60% of the control performance and the highest level has been about 80 percent for three months. Synrzysty properties of plant compounds tested using the fungus B. bassiana right mix in terms of the final formulation for the management of warehouses, expects sawtoothed beetle is jagged. This combination of performance fungus B. bassiana increased, while decreasing consumption in terms of storage and final formulation of the problem to increase the impact speed as a powerful economic and dates are stored in the integrated pest management. Stay in the packaging and into the palm of the hand, reducing the threshold value based on international standards enabling economic losses are more costly methods. This combined with packaging and atmosphered controlled heat treatment is recommended.
