Abstract: A rapid method to detect and/or remove mobile insects inside granular material is presented. The core of this method is to heat grain samples to the desired temperatures (about 55 C) using microwave or radio frequency energy to force insects to move out of the granular material.

Abstract: Novel microwave devices capable of monitoring pest activity or moisture content in grain. A planar active microwave resonator with a regenerative element is placed in proximity to the grain to be tested, for example by immersion within in a bulk grain store to monitor moisture levels or pest activity therein, mounting within a sample container to monitor moisture levels or pest activity in a smaller volume of grain sampled from a grain store or shipment, or exposure to individual sample kernels for detecting internal pests therein.
