Espécies de Trichogramma (Hymenoptera: Trichogrammatidae) coletadas em armadilha de sucção em reserva florestal

Abstract

For the first time an electrical suction trap was used to collect specimens of Trichogramma. The total of 551 Trichogramma specimens were collected belonging to nine species namely T. acuminatum Querino & Zucchi, T. alloeovirilia Querino & Zucchi, T. bruni Nagaraja, T. parrai Querino & Zucchi, T. pretiosum Riley, T. pusillus Querino & Zucchi, T. tupiense Querino & Zucchi, T. zucchii Querino and Trichogramma sp. aff. pintoi. T. bruni was the most abundant and frequent species. The relative frequency was less than 2% for the remaining species. The electrical suction trap was shown useful to collected Trichogramma specimens in areas where host insect eggs are difficult to find.
