Would an electronic system be able to tell the difference between a few nearby mozzies, and a large number of more distant mozzies? |
|

A single mosquito generates a single tone, which wobbles in frequency as the mosquito changes velocity and direction. |
|
| |
A host of mosquitoes will generate a host of such tones, which can be distinguished by suitable processing of the signal - I think it can be accomplished by a host of tracking filters, each monitoring one mosquito each. |
|
| |
By the same method, it might be possible to distinguish between hungry lasses looking for a blood meal, hopeful lads hovering around for them to arrive, and laden matrons flying away satiated in short hops. |

What about squitos that are not in flight? You could use a trap that counts catches/hour giving you a better effective count. |

I guess you have never encountered the kind of situation where they are all just sitting around on the bushes, and rise up in a great cloud as they smell your breath. (I understand they track carbon dioxide, although I am still not sure why that doesn't mean we end up eating them, instead of getting stung.) |

A friend recently described a project in which the sound of keystrokes in a (quiet) room can be analyzed, and reliable transcriptions made using a single microphone. Raises some interesting security issues, when coupled with standard "bouncing a laser off a nearby window" technology for eavesdropping. </sr> |
