This is the first report of Euplectrus floryae (Hymenoptera: Eulophidae) in Brazil and also the first report of this species parasitizing larvae of Erinnyis ello (Lepidoptera: Sphingidae) on cassava. The occurrence of E. floryae on larvae of this pest on cassava opens up the possibility to integrate this natural enemy in biological control programs for cassava crops. Source

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.
