دراسة أولية لتأثير أشعة الميكروويف في حشرة سوسة القمح (Coleoptera : Curculionidae)‎ Sitophilus granarius (L.)‎

Abstract EN

This study was conducted to examine a modern technique to control store insects by using microwave radiation of various powers and different exposure periods.

A microwave oven of 2.45GHz frequency and 600 W power was used.

The infested wheat grains of 12% RH, were exposed to three levels of microwave power (281W, 491W and 561W) for various exposure periods ranging between 25 and 40 seconds at 5 seconds interval.

The power of microwave radiation was used to kill different stages of Sitophilus granarius L.

(adult insects, eggs, larvae, and pupae).

Result showed that microwave radiation has an excellent ability to kill all stages of the insect.

The effect of the microwave radiation increased with raising up the power level and extending exposure period.
