Tree monitoring with seismic-sensorREMOTE VIBROACOUSTIC SURVEILLANCE OF TREES AND WOODEN STRUCTURES AGAINST BORERS
Listening to the trees: We introduce a remotely controlled device that records and wirelessly transmits on a scheduled basis, short recordings of the internal vibrations of a tree to a server.
In short, it contains a piezoelectric transducer (i.e. not a microphone, rather a ‘seismometer’) that turns into recordings the vibrations originating from pests feeding and moving inside the tree (borers).
Two modes of operation: a) listen in situ through earphones, or b) transmit the recordings to the INSECTRONICS server. Customers have free access to the server.
The user can listen remotely to infer the infestation state of the tree with wood-boring insects that feed or move inside the tree. The recordings can be downloaded from the server. It is compact and weatherproof, suitable for functioning in the field.
No need to recharge, it has an embedded solar panel that provides enough power for its low-power electronics.
Included: 2 drill bits, 2 adapters for drill bits that also function as waveguides, 2 independent waveguides, earphones, a device.
We also provide a touch prove so that one does not drill (e.g. for timber evaluation).
Targeted pests: Xylotrechus chinensis, Rhynchophorus ferrugineus (Red palm weevil), mountain bark beetle, Rhynchophorus palmarum, Aromia bungii (Red necked longicorn), Anoplophora glabripennis (Asian longhorn beetle) and Anoplophora chinensis (Citrus longhorn beetle).
WINGBEAT RECORDER OF FLYING INSECTS
WINGBEAT RECORDER OF FLYING INSECTSThe device’s intended use is to automatically record insects’ wingbeating events as they cross the sensor’s probe volume.
It is an optoelectronic device for lab use based on infrared light not visible to human eye. The emitter and the receiver are based on Fresnel lenses. The device senses whatever moves between emitter and receiver, records the light fluctuations due to the casted shadow of the wings and produces an audio snippet in wav format that is stored along with temperature, humidity and a time-stamp of the event. The snippets are stored automatically in its SD card and can be processed with any audio processing program including Matlab and Python. Data can also be automatically uploaded to the Insectronics and retrieved from there.
It has been extensively tested to record the wingbeat of Aphides, Culicoides, fruit flies, bees and mosquitoes. Typically, the sensor is inserted in a BugDorm type insectary cage or in conjunction with a transparent confinement enclosure as seen in the accessories or tethered using a inverted tweezer.
Targeted insects: Any flying insect
