Interaction of electromagnetic waves with granular agricultural product and insects.

The basic correlation is defined which characterizes an influence of electromagnetic radiation on a system of individual particles of ellipsoidal geometry dispersed into some volume (chaotic arrangement) of another medium. The field intensity inside one isolated particle is determined depending on the parameters of the external (relative to the volume) electromagnetic field. Energy loss in an isolated particle is calculated.

Complex high-frequency technology for protection of grain against pests.

The results of experimental investigation of physical methods are presented for suppressing of biological activity of grain and grain product pests: harmful insects at each developmental stage except eggs (Insecta), mites (Arachnida, Acariformes) and microscopic fungi and bacteria. The technologies under development for disinfestation and disinfection of grain are based on irradiation of grain by modulated pulses of high-frequency (HF) electromagnetic fields and on simultaneous action of a complex of factors: vacuum and HF-field induced plasma. The threshold value of the electric field intensity for total insect mortality was found to be E = 4.
