Lidar reveals activity anomaly of malaria vectors during pan-African eclipse. [PDF]
Sci Adv, 2020 Yearly, a quarter billion people are infected and a half a million killed by the mosquito-borne disease malaria. Lack of real-time observational tools for continuously assessing the unperturbed mosquito flight activity in situ limits progress toward ...

Unbiasing entomological kHz Scheimpflug LIDAR data [PDF]
, 2018 Insects can be mapped using a method called Scheimpflug Lidar (LIght Detection And Ranging). Sending out light in the near infrared range and detecting the backscattered echo, it is possible to resolve flying organisms in range and time.

Bark beetles as lidar targets and prospects of photonic surveillance
Journal of Biophotonics, Volume 14, Issue 4, April 2021., 2021 Precise monitoring of European spruce bark beetle, Ips typographus, is necessary for fighting bark beetle infestation early. In this work, optical properties, wing thickness, and WBF of bark beetles are reported, and these parameters infer target identity in lidar data. Lidar results from a Swedish forest with a controlled bark beetle release event are
