Popis: | This research studied the thermal requirements of Trichogramma pretiosum and T. acacioi (Hymenoptera: Trichogrammatidae), parasitoids of Nipteria panacea (Lepidoptera: Geometridae), with eggs of the alternative hosts Anagasta kuehniella (Lepidoptera: Pyralidae) and Sitotroga cerealella (Lepidoptera: Gelechiidae) aiming to use these natural enemies in biological control programs of this pest in avocado orchards. T. pretiosum needed 151.83 and 160.04 degree-days, above threshold of 10.70 and 10.75°C, while these values were 158.50 and 155.46 degree-days, above threshold of 10.67 and 10.46°C for T. acacioi when exposed to eggs of A. kuehniella and S. cerealella, respectively.O objetivo desta pesquisa foi estudar as exigências térmicas de Trichogramma pretiosum e T. acacioi (Hymenoptera: Trichogrammatidae), parasitóides de Nipteria panacea (Lepidoptera: Geometridae), em ovos dos hospedeiros alternativos Anagasta kuehniella (Lepidoptera: Pyralidae) e Sitotroga cerealella (Lepidoptera: Gelechiidae) visando utilizar estes inimigos naturais em programas de controle biológico desta praga em pomares de abacate. T. pretiosum apresentou temperaturas base (Tb) de 10.70 e 10.75°C e constantes térmicas (K) de 151.83 e 160.04 graus-dia, sendo estes valores de 10.67 e 10.46°C e 158.50 e 155.46 graus-dia para T. acacioi em ovos de A. kuehniella e S. cerealella, respectivamente. |
