Ultrasound causes flying lacewings to fold their wings and drop, an effective maneuver for evading capture by bats. [22] Some tettigoniids use a similar strategy, [23] although other species respond much like crickets. [24] Several other insects have sensitive ultrasonic hearing that probably is used in bat evasion, but direct evidence is not ...
Over a nine-night experiment the bats attacked non-clicking control moths and clicking Bertholdia trigona – moths that were selected for their extraordinary clicking abilities. Bats had substantial difficulty catching the clicking moths compared to silent controls, and ate the B. trigona moths when they had the opportunity, thus refuting the ...
Electronic pest control is the name given to any of several types of electrically powered devices designed to repel or eliminate pests, usually rodents or insects. Since these devices are not regulated under the Federal Insecticide, Fungicide, and Rodenticide Act in the United States, the EPA does not require the same kind of efficacy testing that it does for chemical pesticides.
The species Bertholdia trigona has been shown to jam bat echolocation: when pit against naïve big brown bats, ultrasound was immediately and consistently effective at preventing bat attack. Bats came in contact with silent control moths 400% more often than with B. trigona. [97]
A bat detector is a device used to detect the presence of bats by converting their echolocation ultrasound signals, as they are emitted by the bats, to audible frequencies, usually about 120 Hz to 15 kHz.
Rats are consuming drugs that were seized and stored by Houston police and hundreds of cases could be vulnerable to the rodent infestation, officials said.
The SM2BAT can record two channels simultaneously allowing a second microphone to be mounted up to 100m away from the recorder. With 4 SDHC cards the device can record about 240 nights of bat calls. [6] In August 2009 a one channel 384 kHz sample rate version was added to allow recording of higher frequency bats common in some areas of Europe. [7]
