Labroratoryuse of some insecticides and microwave technology in the control of red flour beetle castaneum (Herbst ) (Tenebrionidae: Coleoptera) Tribolium

Abstract

"The study was carried out to effect of some pesticidesand microwave in red flour beetle in plant protection Department of Agriculture, Basrah University. it was observed that there was a significant difference between the exposure of chemical pesticides and the treatment of control ,as the effect of the larvae death was Deltamethrin pesticide affected the percentage of the destruction of the last larva age and adults stage . The percentage of larval 88.66% compared with the Alpha-cypermethrin and Vapcocidinwere their percentage in which the rate 72.2%and 64.2% respectively. The effect of exposure on the percentage of adult mortality 85.0, 68.8 .53.9% for both Deltamethrin, Alpha-cypermethrin and Vapcocidin respectively. Was superior to the Deltamethrin the mortality rate for larvae and adults 93.53% and 91.5% respectively. The study showed that percentage of mortality of larval and adult increased with increase exposure time and increase intensity of microwave and the highest percentage was at exposure time 20 second, where the mortality rate 100% for the last larva age and adults when the intensity of 800 watts, and did not affect the levels of microwave in the proportion of germination of wheat grain treated as the results of the statistical analysis showed no significant different between treatments and control."
