عنوان المقالة: VALUATION OF OXYGEN DEPLETION TECHNOLOGY USING NITROGEN GAS TO CONTROL MOVING STAGES OF RED FLOUR BEETLE TRIBOLIUM CASTANEUM (HERBST) (COLEOPTERA: TENEBRIONIDAE)
The study was carried out to evaluate the efficiency of nitrogen gas to depletion of oxygen and my cause mortality the insects moving stages(Larvae and Adult), the results showed ,The primary larval stage was the weakest age among larval ages in concentrations 15 and 30% respectively, mortality rates reached 63.00, 86. 66 at the first day of exposure time and100,100% at exposure time 6,3 day respectively, While the advanced age was the most resistant in the concentrations15 and 30% respectively, with the results of rate mortality reached 30 and 33. 33% in the first day of exposure time and 83.33, 100% at exposure time 7,5 day respectively, The results showed that males were more sensitive than females in the 30% concentration, the mortality rate reached 100% at the exposure time 1 and 2 days for males and females respectively. The results showed that the 30% concentration was the best in the mortality rates, and there is a positive correlation between the mortality rates , increased the exposure time and increase nitrogen concentration in both stages (larvae , adult).
