In this work, the effect of adding the minor component to the basic components of the sex pheromone of the plum fruit moth was evaluated in field trials in plum orchard. The addition of 75% of the minor component to the pheromonal composition increases the male capture of the plum fruit moth Grapholita funebrana Tr. by up to 25.8%, a result comparable to the one obtained the previously.
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.
