This invention relates to an adaptive detection system and method for analyzing range-doppler-azimuth data for target detection. Circuitry is provided for harvesting the electrical charge from the resonant beam. In addition, the invention provides methods for controlling Varroa mites that can weaken a hive or act as vectors for bacterial diseases. A second channel branches from the first channel to receive particles diverted and separated from the flow of the fluid in the first channel.
