Lindgren funnel trapping

[bathcat]

I came into a pair of Lindgren funnel traps and am now looking at lures to catch some wood borers. So far, people have been recommending alpha-pinene UHR and Ethanol UHR from Synergy Semiochemicals Corp. as "all-purpose" lures that will give me a wide variety of species, so that parts covered.

The other question is, what is it that attracts Rosalia funebris? Males are known to come to white paint drying on the side of buildings, but nobody seems to know exactly what brand does it or what component in the paint is causing the attraction. There was a paper identified a male produced aggregation semiochemical, www.life.illinois.edu/hanks/pdfs/Ray%20et%20al%202009a.pdf, but that would be costly to purchase by itself.

Anyone have any experience with funnel traps? If so, what do you use as lures?

Hi Bathcat,

You're correct in using the EtOH and a-pinene lures as good general lures. The EtOH is great for woodborers in general, while the a-pinene is more specific for conifer feeders. You can't go wrong with these two, and running both lures on a single trap works fine - they compliment, rather than interfere with one another. Most lures beyond these become more refined for attracting specific genera, so their effectiveness for general collecting becomes lessened.

As for the Rosalia - that's a mystery to me as well. The anecdotal "white paint" is all I've seen referred to on numerous occasions, but no further details. Of course, we don't have Rosalia in the East, so I've never investigated details for trapping it.

I don't have any experience with the Hanks lure, but I have heard that they are quite effective for Cerambycidae. If you try it, report back here with the results.

Cheers!
