| La broca del café, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae), es la plaga mas importante del cultivo de café en el mundo. Beauveria bassiana es un hongo entomopatógeno generalista ampliamente utilizado por los productores de café para controlar a H. hampei. Phymastichus coffea LaSalle es un endoparasitoide africano de adultos de la broca, recién importado a varios países de Latinoamérica y del Caribe para el control de esta plaga. En el presente estudio se realizaron bioensayos de laboratorio con el objetivo de determinar si B. bassiana es detrimental para el parasitoide P. coffea. La susceptibilidad del parasitoide fue evaluada en términos de supervivencia de adultos, concentración letal media (CL50), tiempo letal medio (TL50),... |

| The importance of age and feeding on the performance of Cephalonomia stephanoderis (Hymenoptera, Bethylidae), a parasitoid of the coffee berry borer, Hypothenemus hampei (Coleoptera, Curculionidae) was investigated in the laboratory. Groups of female parasitoids were subject to the following treatments: a group fed during one, five and ten days after emergence of adults with coffee borer larvae; another group fed only with honey solution during five days after emergence; and as a control, a third group was kept without food for five days. At the end of each treatment, survivorship, parasitoid activity (walking and flying capacity in an arena), search capacity for finding coffee borer-infested berries, host feeding and oviposition (on immature hosts), were... |
