BARRIA, Manuel D.; QUIROS, Dora Isabel  y  EMMEN, Daniel. Bioacoustic analysis of a compound sound with stridulation and forced air produced by the larva of Phileurus valgus (Olivier, 1789) (Coleoptera: Scarabaeidae: Dynastinae: Phileurini). Rev. chil. entomol. [online]. 2021, vol.47, n.2, pp.187-194. ISSN 0034-740X.  http://dx.doi.org/10.35249/rche.47.2.21.02.

It was observed that Phileurus valgus larvae are capable to emit stridulation and forced air sound when disturbed, being able to emit a “compound sound”. Duration, frequencies, oscillograms, spectrograms of the sounds obtained are presented. The results obtained are compared with previous studies and the possible communicative or warning functions they may have in their natural environment when interacting with other larvae (other species) or their congeners (same species). The audios obtained in the study are shared.

Palabras clave : Bioacustic; disturbance; oscilograms; phileurines.
