Since this is the second message, that came across the net, I am passing
on a post from an entomology friend. He also maintains an entomology www
site at Iowa, which is very nice.
Here is the post.>collection of effective mediums. I've heard that octenol is one such

There is a wealth of literature on this topic. Pick up any issue of the
Journal of the American Mosquito Control Association or the Journal of
Medical Entomology and you'll probably run across an article or two.
CO2 is by far the most commonly used. Octenol works for some genera but not
others (in combination with CO2) and lactic acid works in combination with
CO2. Other approaches are live baits (malaise traps) or aspirator/suction
traps (see many articles by Bidlingmayer).
The method you choose will depend on your objective. Engorged mosquitoes
may come to oviposition attractants; host-seeking mosquitoes will come to
