title: [The effect of microwaves (UHF) and magnetic fields on the insecticidal properties of biological and chemical preparations].
abstract: 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. The higher activity of dursban irradiated with a magnetic field was demonstrated to retain for over 2 months.
