Conteúdo: |
Natural parasitization of Spodoptera frugiperda (J.E. Smith) and Helicoverpa zea (Boddie) eggs by Trichogramma spp. occurred in all corn test plots. The highest levels occurred when corn was planted in March. Parasitism of Spodoptera frugiperda by Trichogrammapretiosum Riley was usually less than 20%, while parasitism of eggs of H. zea commonly exceeded 50%. Parasitism of singly laid eggs of H. zea was higher than eggs of S. frugiperda, which are laid in overlapping layers and protected by scales. |
