I am planing an experiment to investigate the dispersion ability of Trichogramma dendrolimi under semi-field conditions. As far as I know Trichogramma uses kairomones for host finding but are visual cues also important? I want to place bait eggs of Dendrolimus pini glued to a cardboard in different distances from the point of release of T. dendrolimi and to check if they are parasitised. I just don't know if the color of the cardboard makes a difference. Is it better to use green (as the eggs and the needles of the trees) or any other color and does the color matter after all?
