NONATO DE OLIVEIRA, HARLEY; COLA ZANUNCIO, JOSÉ; FAGUNDES PEREIRA, FABRÍCIO  e  PRATISSOLI, DIRCEU. Trichogramma (Hymenoptera: Trichogrammatidae) species as an agents of biological control of Oxydia vesulia (Lepidoptera: Geometridae). Rev. Colomb. Entomol. [online]. 2011, vol.37, n.2, pp.238-239.

Lepidoptera defoliators are important pests of Eucalyptus. This research aimed to evaluate the potential of Trichogramma acacioi and Trichogramma pretiosum (Hymenoptera: Trichogrammatidae) to control the eucalyptus defoliator Oxydia vesulia (Lepidoptera: Geometridae). Biological parameters and parasitism rate of Trichogramma on eggs of O. vesulia were evaluated under laboratory conditions. Trichogramma pretiosum did not parasitized eggs of O. vesulia but more than 93% of T. acacioi females parasitized eggs of this defoliator, showing its potential for the biological control of this Lepidoptera.
