Hi Gang,
On the ABC last night there was a segment about a bunch of school kids who did a science project on spiders. One of the techniques they used to collect the spiders was to leave a diesel Troopy idling and it would attract bugs to the vibration. They said that all sorts of animals and bugs are attracted to the vibrations, particularly those of a diesel.
I suppose this is another one of those bushy things that everyone but me already knows about. I sure won't be running my engine in a
campsite any longer than I need to in future.
Cheers Frank

Ahh, I feel safe then. I've had the Rodeo for 7 months now at not one
sign of spiders anywhere!
It's a smooooooth V6 petrol.
Interesting about the vibrations though. I watched a doc. on spiders once and the males would tap on their web to attract females for mating.
If the female didn't like the "beat" they just simply ate the male! Typical. hehe.
Maybe the Troopies have got some serious mojo goin on? All for the wrong species though

The program was the 7:30 report. The transcript from the ABC website quotes

MURRAY MCLAUGHLIN: Those later consignments were gathered by a more arcane method, which even scientists can't fathom - a motor vehicle, preferably diesel powered because it vibrates more than a petrol engine, is parked in the bush with the engine running to attract spiders.
DR ROBERT RAVEN: We do know now, from large collections held in the South Australian Museum, that the curator there figured out that if you leave a four-wheel drive or a tractor idle that a lot of animals will come to the vibration. And, you know, most of the collection in the South Australian Museum has got the word "vibration" on it and that's how we got them.
MURRAY MCLAUGHLIN: The trick seemed to work in
Maningrida. The students did comparative studies to prove the point.
SCIENCE STUDENT #1: We turned the car on and caught, yeah, 15 spiders. But when the car was turned off, we caught only two spiders. So, we caught more spiders when the car was on.
Unquote:
The show referred to Dr Robert Raven as Australia's leading expert on spiders. If he and the South Australian Museum believe this to be true, that's good enough for me.
Cheers Frank.
