The antifeedant and insecticidal properties of the two-species intensive culture of the marine microalgae, Platymonas viridis Rouch. and Nephrochloris salina Carter, were tested at the larval phases of the development of Leptinotarsa decemlineata Say and Hyphantria cunea Drury. The experiments were carried out using the native culture, its supernatant and pellet, the cultures differing in the content of nitrogen and phosphorus, and cultures exposed to thermal shock (freezing-thawing), as well as ethanol extracts of the pellet neutralized by calcium carbonate etc. It has been found that the trophic function of insects was distinctly inhibited during three-four days after the onset of the experiment. It has been also shown that the microalgae (native culture and its derivatives) demonstrate toxic activity, in this case, H. cunea was subjected to the inhibitory effect to a greater extent. The role of the factors adversely affecting the biological activity of intensive culture of microalgae is discussed.
