Rolul componenţilor minori asupra eficienţei feromonului sexual al viermelui merelor

Abstract

In this paper, the influence of the addition of minor components: trans-8, trans-10-dodecadienal; trans-9-dodecenol; tetradecanol on the biological effectiveness of the basic component (Basic component E8,E10-C12OH) of the synthetic sex pheromone of the codling moth Cydia pomonella L. was evaluated. Pheromonal compositions have been prepared by adding different concentrations of these minor components to the basic component. The best result in field tests was shown by the variant where rubber dispensers contained 4% of each minor component.
