Rhynchophorus palmarum es plaga relevante en palmeras (Arecaceae) en Brasil. Su respuesta comportamental (olfatometría) y electrofisiológica (electroantenografía, sola y acoplada a cromatografía) se estudió frente a compuestos orgánicos volátiles emitidos por hongos entomopatógenos nativos aislados en Coruripe (Alagoas, Brasil) mediante aireación durante 24 horas. El aislado CVAD01 no originó respuesta comportamental significativa, pero el CVAD02 originó atracción significativa en machos. Los bioensayos electrofisiológicos mostraron actividad antenal en los dos sexos de R. palmarum frente a los componentes volátiles de los extractos de los dos hongos identificados. Los análisis cromatográficos de los extractos indicaron perfiles de compuestos orgánicos volátiles con la presencia de dos alcoholes, tres hidrocarburos aromáticos, dos monoterpenos, tres cetonas y tres hidrocarburos lineales. Rhynchophorus palmarum is a major pest of palms (Arecaceae) in Brasil. Both the behavioral (olfactometry) and electrophysiological (electroantennography, both alone and coupled to chromatography) was studied against volatile organic compounds emitted by native entomopathogenic fungi isolated from Coruripe (Alagoas, Brazil). Fungal isolates were identified by aeration system for 24 hours. CVAD01 did not cause a significant behavioral response; however, males were significantly attracted to CVAD02 extracts. Electrophysiological bioassays showed antennal activity, in both sexes, to volatile components of the two identified native fungi. The chromatographic analysis of the extracts indicated profiles of volatile organic compounds with the presence of three alcohol, three aromatics, three ketones, and four hydrocarbons.
