Dear Bioacoustics community,
I would like to present two open source papers on bioacoustics applications
related to insects.
The first one introduces the possibility of remote vibroacoustic monitoring of
trees against borers at large scales. A piezoelectric probe is inserted at the
base of the main branches joining the trunk (or near the stem in the case of
palms) and every hour uploads small recordings of the internal vibrations due
to larva motion and feeding to a cloud server. The user can listen to these
recordings and decide upon the infestation status by examining a longer time
span than is currently done (e.g. on a weekly or monthly basis). In the near
future the examination of the vibroacoustic recordings will be automatic and
expandable to a large number of trees using the LoRa network. The device is
currently sufficient to operate for 3 months without recharging but we aim at
its permanent installation based on power harvesting techniques.

The second paper is on a multispectral wingbeat recorder of backscattered light
that aims to analyze the photoacoustic wingbeat of flying insects but also
extract a deeper representation of the melanization and coloration of these
insects. Different versions of this approach are currently installed at the
gates of beehives to count foraging activity and tag species identity, as well
as in agricultural e-traps that report on the identity and sex of incoming
flying insects.
