Abstract

BASSO, César  and  PINTUREAU, Bernard. Trichogramma species from Uruguay (Hymenoptera: Trichogrammatidae). Rev. Soc. Entomol. Argent. [online]. 2004, vol.63, n.1-2, pp.71-80. ISSN 0373-5680.

Five Trichogramma Westwood species were collected in Uruguay. The widely distributed T. pretiosum Riley parasitizes Diatraea saccharalis (Fabricius), Heliothis zea (Boddie), Alabama argillacea (Hübner) and Argyrotaenia sphaleropa (Meyrick). Trichogramma exiguum Pinto & Platner, often confused with T. fuentesi Torre, parasitizes Bonagota cranaodes (Meyrick) and A. sphaleropa. The two species T. galloi Zucchi and T. distinctum Zucchi parasitize D. saccharalis. Their morphology is relatively close and, from the information available, it is not possible to decide if they are closely related species or synonymous species. Finally, up to now, T. bellaunionense Basso & Pintureau was only collected from Uruguay on D. saccharalis. An illustrated key is provided to identify these five species. Moreover, the present and expected use of Trichogramma to control different pests in different Uruguayan crops is reviewed.
