[The effect of microwaves (UHF) and magnetic fields on the insecticidal properties of biological and chemical preparations].

The larvicidal activity of preparations from different groups of compounds was assayed after their exposure to microwaves and magnetic field. The radiation was found to have a varying impact on the insecticidal properties of the preparations. Thus, the efficiency of spheric larvicides decreased, which is likely to be associated with the structural changes of toxin crystals, whereas the larvicidal activity of the organophosphorus compound dursban and the pyrethroid aikon increased 2-5-fold.

[Changes in the acaricidal properties of organophosphorus compounds under the influence of magnetic resonance treatment].

The authors demonstrate the possibility of enhancing pesticidal properties of some organophosphorus compounds by their single treatment for 40 min by pulsed magnetic field, 100 kHz, 10-15 microT with 16 Hz sinusoidal modulation. The treatment efficacy is up to 30 days.
