was that the same fruit fly as our tropical fruit fly?

if so this will be a boon for tropical gardeners.

should be no difference between coke and pepsi as far as i know one is
based on orange juice and the other lemon juice. outside of that they
are basically a sugar and caffien drink, nothing exotic in them.

Hi Len. I don't believe there was any suggestion of the Coke lure
being species specific when it comes to fruit flies. With any
luck they'll all dive in! The Coke lure may not be any more
effective than those based on other kitchen ingredients, but the
fact that he took no steps to hinder the flies from escaping
impressed me, because I have closely watched how the flies will
make an enduring attempt to escape from bottle traps fashioned to
have the inverted funnel in their neck. He did have lots of traps
hanging up everywhere, though.

It was either Sydney or Melbourne, I just forget which.

As you'd agree, it's really not the number of flies that get
trapped that you need to be concerned with, it's how many that
manage to get past it!
