Resumo ABSTRACT. Bt sweet corn is attacked by species of the genus Euxesta Loew that were considered as secondary pests, causing severe damage to sweet corn in Santa Fe province (Argentina). Two species have been identified: E. mazorca Steycal and E. eluta Loew, both appearing simultaneously and producing serious losses. Larvae attack the silks and consume the kernel contents, especially in the tips, although they can extend to all the ear length. The activity of these larvae constitutes one way of entrance for saprophytic microorganisms, making the product unmarketable for direct consumption. Dettmeria Borgmeier (Hymenoptera: Figitidae) was identified parasitizing larvae of the genus Euxesta, but at a low level.
