dc.descriptionThe objective of this work was to evaluate the parasitism capacity of Trichogramma pretiosum Riley and T. acacioi Brun, Moraes and Soares (Hymenoptera: Trichogrammatidae) in eggs of the alternative host Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae) aiming to use both species in biological control programs of Nipteria panacea Tierry-Mieg (Lepidoptera: Geometridae). The parasitism rhythm and total parasitism of these parasitoid species were affected by the temperature with higher values during the first 24 h of their life. Parasitism period was longer for T. pretiosum and T. acacioi at the lowest temperature.
dc.descriptionO objetivo deste trabalho foi estudar a capacidade de parasitismo de Trichogramma pretiosum Riley e de Trichogramma acacioi Brun, Moraes and Soares (Hymenoptera: Trichogrammatidae) em ovos do hospedeiro alternativo Sitotroga cerealella (Olivier) (Lepidoptera: Gelechiidae), visando o uso desses inimigos naturais em programas de controle biológico da praga do abacateiro Nipteria panacea Tierry-Mieg (Lepidoptera: Geometridae). O ritmo de parasitismo de T. acacioi e T. pretiosum variou com a temperatura, sendo maior nas primeiras 24 horas de vida desses parasitóides. Além disso, o período de parasitismo foi maior para essas duas espécies de parasitóides na menor temperatura, enquanto o parasitismo total por fêmea variou com a temperatura.
