O embrião de Thyrinteina arnobia (Lepidoptera: Geometridae) pode produzir proteção ao parasitismo de espécies de Trichogramma?
[Can the embryo of Thyrinteina arnobia (Lepidoptera: Geometridae) protect itself against parasitism by Trichogramma spp.?]
IDESIA (Chile) 24 (3), 65-67
Abstract: Defoliator caterpillar cause damages in Eucalyptus plantations. A control alternative is the use of Trichogramma which, even though has been found parasitizing some species in Eucaliptus, does not meet cases of T. arnobia parasitism. The objective of this research was to evaluate the parasitism of Trichogramma pratissolii Querino and Zucchi (Hymenoptera: Trichogrammatidae) on unviable T. arnobia eggs. Unviable T. arnobia eggs were glued on light blue cardboard rectangles, and exposed to the parasitism of T. pratissolii for 24 hours. After this period there was observed 100% mortality of the individuals, though the glued eggs did not present parasitism.
