Temptress wasps lure from afar
Interesting article from ABC Science. Watch out, it could be R rated!
Didn't know that orchids also emit pheromones. I thought it was a purely visual attraction. More at: http://www.abc.net.au/science/news/stories/s1026385.htm "Female wasps become more sexually attractive as they walk away from orchid sex traps, according to an international team of researchers. The results of the study led by PhD student Bob Wong, from the Australian National University, were published this week in the Royal Society journal Biology Letters. The researchers looked at how the south-eastern Australian orchid Chiloglottis trapeziformis sets up a sex trap for the wasp Neozeleboria cryptoides." -- Reka I don't give a damn for a man that can only spell a word one way.

More at: http://www.abc.net.au/science/news/stories/s1026385.htm I've seen this article before but I'm not really surprised that orchids that rely on pseudocopulation for pollenation release pheromones. I guess there's no use in Chilloglottis going to the effort of evolving wasp-like arrangements of calli on their labellums if they don't smell like the insects in question. Andrew |
