Abstract:Trichogramma (T. minutum) liberated in a block of 121 trees without parasites dispersed in all directions and resulted in 50 per cent parasitism. One other orchard with low parasitism increased 53 per cent after a single liberation. A third orchard having high natural parasitism was not increased by large liberations. The parasite flew 24 feet under laboratory conditions.
