          Abstract

          Prorops nasuta Waterston (Hymenoptera: Bathylidae) es un ectoparásito que se alimenta de todos los estados inmaduros de la broca del café, Hypothenemus hampei Ferrari (Coleoptera: Curculionidae: Scotylinae) y que se reproduce depositando sus huevecillos en la parte ventral de las larvas maduras y pupas de su huésped. Estudios previos han demostrado que este parasitoide es atraído a los olores provenientes de los desechos alimenticios y fecales de su huésped. Este estudio investigó el efecto de algunos factores tales como edad, alimentación, sexo y experiencia de oviposición en la respuesta del parasitoide P. nasuta a los olores provenientes de los desechos de su huésped. Los bioensayos se realizaron en un olfactómetro tipo "Y". Los resultados muestran que las hembras de P. nasuta sin alimentar y alimentadas con miel-agua prefirieron significativamente los olores provenientes de los desechos que al control. En contraste, las hembras alimentadas con inmaduros no mostraron ninguna preferencia por los olores de los desechos o por el control. Los resultados muestran que la edad de las hembras no influyó en su respuesta a los olores de los desechos de su huésped. Los machos de P. nasuta no fueron atraídos a los olores provenientes de los desechos. La previa experiencia de las hembras no influyó en su respuesta a los olores de los desechos.

          Translated abstract

          The parasitoid Prorops nasuta Waterston (Hymenoptera: Bathylidae) is a wasp that feeds upon and parasitizes the coffee berry borer, Hypothenemus hampei (Ferrari) (Coleoptera: Curculionidae: Scolytinae), which is the most important pest of coffee (Coffea spp.) in the world. Previous studies have shown that P. nasuta females are attracted to the odors emitted by dust/frass of H. hampei. In this study, the effect of age, feeding status, sex and previous experience of P. nasuta on female attraction to the dust/frass odors was investigated in the laboratory using a Y-tube olfactometer. Females without food and those fed with a solution of honey-water (1:1) significantly preferred dust/frass odors over clean air. In contrast, females fed with H. hampei immature stages did not show any preference for dust/frass odors or clean air. Female age did not influence the attraction of P. nasuta to dust/frass odors. P. nasuta males were not attracted to dust/frass odors. Both naïve and experienced females were similarly attracted to dust/frass odors, suggesting that the response of P. nasuta to dust/frass odors is innate.
