Abstract:
In order to test the effect of radio frequencies in rice and wheat flour pest control, the samples were dirtied by Tribolium confusum flour pest and Sitophilus oryzae rice pest. The wheat flour pests were radiated at 13.56 MHz in 10, 20, 30, 40, 45 and 60 sec, at 27.12 MHz in 5, 10, 20, 25, 30, 35 and 60 sec and at 40.68 MHz in 5, 10, 20, 12, 15 and 60 sec. The rice samples were heated at 13.56 and 27.12 MHz in 60, 75, 85, 95 and 105 sec. After above mentioned times, the number of died insects were counted. Quality test of treated flour and rice samples were done after treatments. Based on the results, the mortality of wheat flour pests after 45 sec at 13.56 MHz reaching 45°C, after 35 sec at 27.12 MHz reaching 46°C and after 15 sec at 40.68 MHz reaching 47°C was 100%. Temperature sensitivity of Tribolium confusum at 13.56, 27.12 and 40.68 MHz frequencies were 40, 38 and 43°C, consequently. Also, the results demonstrated that the mortality of rice pests after 105 sec at 13.56 MHz, reaching 57°C and after 95 seconds at 27.12 MHz, reaching 58°C was 100%. Temperature sensitivity of Sitophilus oryzae at 13.56 and 27.12 MHz frequencies were 48 and 50°C, in order. The combination of the results showed that pest control potency and intensity increases as frequency rises.
