Abstract

Knowing the parasitoids that attack aphids is important as tools for integrated management. The present work was carried out in Irapuato, Guanajuato, Mexico. Hordeum vulgare, Brassica oleracea var. italica, Ficus benjamina and Amaranthus spp. Diaretiella rapae (Hymenoptera: Apidiidae) parasitized Brevicorynebrassicae in 60.8% and Myzus persicae in 73%; Schizaphis graminum was parasitized by Aphidius spp in 48% and Lysiphlebusspp with 26.6%, Aphis spp in amaranth was parasitized by Aphidius spp in 73.3%. It is suggested to establish strategies to conserve this parasitoid due to its ability to parasitize aphids.
