Abstract

This work aimed to evaluate cold plasma (150, 200 and 250 voltages at 1-25 minute exposure times) as a promising alternative method to control immature stages of Corcyra cephalonica (Stainton) and Stegobium paniceum (Linnaeus) compared with argon 100%, nitrogen 99% and ozone (100 ppm) at different exposure times between 2-96 h. The results obtained showed that the reduction percentage of adult emergence increased with increasing exposure time. At 250 V, data revealed that complete reduction after 12, 15 min in egg and pupa stages, respectively in both insects but in larvae stage after 10 and 12 min of exposure for S. paniceum and C. cephalonica. On other hand, the complete reduction in larvae stage of C. cephalonica were recorded after 96 and 24h exposure with  argon and ozone , respectively while the same results were recorded in S. paniceum after 96 and 12h for argon and ozone. It's clear that cold plasma is the most efficient technique for controlling the stored product pests.
