ABSTRACT
Aerodynamic sorting of host eggs exposed to Trichogramma egg parasitoids improved the percentage parasitism of retained product. Losses of parasitised eggs declined as percentage parasitism of the unsorted eggs increased. Trichogramma eclosion from parasitised eggs was similar for the unsorted and retained fractions; emergence from the parasitised culls was significantly lower.
