“…We considered oviposition to have occurred when the female parasitoid adopted a characteristic ovipositing position on the elytra of the scolytids (López-Vaamonde & Moore 1998). Hosts attacked by P. coffea were transferred individually into vials containing CBB diet (Villacorta & Barrera 1996) and parasitization was assessed based on the emergence of the progeny, or by dissecting the hosts that did not yield parasitoids. We also recorded the time required for the encounter (defined as the time elapsed between the release of the parasitoid in the arena until it assumed the characteristic ovipositing position on the beetle), and the handling time (defined as the time elapsed between the encounter and the end of parasitization).…”

“…Los insectos permanecieron en contacto con la suspensión del hongo durante treinta segundos y después fueron colocados sobre un papel fi ltro para eliminar el exceso de humedad. Las brocas inoculadas fueron colocadas individualmente en viales que contenían 2 ml de una dieta (Villacorta & Barrera 1996). Las brocas fueron disecadas 24 días después para determinar el porcentaje de infección.…”

-The coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae), is the most important coffee pest worldwide. Beauveria bassiana is a generalist entomopathogenic fungus widely used by coffee farmers to control this pest and Phymastichus coffea LaSalle (Hymenoptera: Eulophidae) is an African endoparasitoid of H. hampei adults, recently imported to several Latin American and Caribbean countries to aid in the coffee berry borer control. The objective of this study was to determine if B. bassiana is detrimental to P. coffea. The susceptibility of the parasitoid was evaluated in terms of adult survivorship, mean lethal concentration (LC 50 ), mean lethal time (LT 50 ), reproduction and immature mortality. The main effect of the fungus resulted in reduction of adult longevity and mortality of 100% for immature stages of this parasitoid. The LC 50 for adults was 0.11% equivalent to 9.53 x 10 7 conidia/ml of B. bassiana and a LT 50 of 29.4h, equivalent to reduction of 22% of its normal longevity as an adult. P. coffea was capable of disseminating spores of B. bassiana to non-infected H. hampei adults, which could indirectly cause the death of its own progeny. These results could be valuable when considering the use of both organisms in the fi eld, especially in an integrated pest management program.KEY WORDS: Coffee, Hypothenemus hampei, entomopathogenic fungus RESUMEN -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 (CL 50 ), tiempo letal medio (TL 50 ), reproducción y mortalidad de su progenie. El principal efecto del hongo resultó en la disminución de la longevidad de los adultos y en la mortalidad del 100% de los inmaduros del parasitoide. La CL 50 para adultos de P. coffea fue de 0.11% equivalente a 9.53 x 10 7 conidias/ml de B. bassiana y una TL 50 de 29.4h, equivalente a la reducción del 22% de su longevidad normal como adulto. P. coffea fue capaz de transmitir esporas de B. bassiana a brocas no infectadas con el hongo y originar indirectamente la muerte de su progenie. Este trabajo servirá de referencia cuando se contemple el empleo de ambos organismos a nivel de campo, especialmente dentro de un plan de manejo integral de la plaga.PALABRAS CLAVE: Café, Hypothenemus hampei, hongo entomopatógeno El cultivo del café (Coffea arabica y C. canephora) tiene importancia económica, social, cultural y ambiental en todo el mundo.

“…The mass reproduction of CBB is a delicate problem involving research into the development and preparation of artifi cial diets (Brun 1993, Villacorta & Barrera 1993, 1996, Portilla 1999). The mass rearing of H. hampei is an important matter to support further studies on this species, but mainly to allow for the production of its parasitoids, such as Cephalonomia stephanoderis Betrem (Hymenoptera: Bethylidade), Prorops nasuta Waterston (Hymenoptera: Bethylidade) and Phymasticus coffea La Salle (Hymenoptera: Eulophidae), which are all important natural enemies with potential for use in applied biological control.…”

Primeiro Registro da Broca-do-Café, Hypothenemus hampei (Ferrari) (Coleoptera: Scolytidae), em Castanhado-Pará, Bertholletia excelsa (Lecythidaceae)RESUMO -Este trabalho registra a ocorrência de Hypothenemus hampei (Ferrari) em amêndoas armazenadas da castanha-do-Pará, no Sudeste do Pará. O inseto obteve sucesso na infestação e reprodução na castanha-do-Pará. Com base nessa constatação, o uso da castanha-do-Pará pode ser uma alternativa para a criação da broca-do-café. Além disso, cabe alertar para os cuidados com armazenamento dessas amêndoas para se evitar a infestação pelo inseto. PALAVRAS-CHAVE: Praga, grão armazenado, criação massalABSTRACT -We report the occurrence of Hypothenemus hampei (Ferrari) attacking Pará nuts stored in the southeast of Para state. The coffee berry borer successfully colonized and reproduced using Pará nuts as a food source. Based on this observation, the Pará nuts can be used as an alternative food source in rearing the coffee berry borer. Also, attention should be brought to need of proper storage of these nuts to avoid infestation by this pest.
