How best to attach piezzo sensors to a leaf to measure insect vibratory signal?
I'd like to measure with a cheap piezoelectric disk the vibration signals sent by whiteflies when resting on leaves. These disks are usually pretty big (I have not found any less 2cm diameter) and ...

Recording of whitefly vibrations: "piezo" versus "low-noise microphone with subtrate-air diffusion"
Whiteflies communicate before and during mating through abdomen oscillations which vibrations are believed to propagate mostly in the leaf (~100-400 Hz). They are very low-energy signals which are ...

Could mosquitoes be attracted to the sound of their blood host?
At long-range, female mosquitoes mostly rely on CO2 to find blood host by flying up-wind following the odor plume (ref). They are also known to have excellent auditory organs (ref1, ref2) involved in ...
