A World of Scents

“Nature is more a world of scents than a source of noise.” That quote sound familiar? Chemical ecologist Jacques Le Magnen (1916-2002) said that back in 1970.World-renowned organic chemist Wittko Francke (right) of the University of Hamburg, Germany,...

Heaven Scent

Talk about deception. Remember the exciting news article published in November of 2009 in Science Daily about how an orchid species on the Chinese island of Hainan "fools its hornet pollinator by issuing a chemical that honey bees use to send an...

Yellowjacket

IF ORCHIDS can trick wasps to pollinate them through a chemical they produce that mimics the scent of their prey, the honey bee, can this type of research be used elsewhere? "Various species of Vespa are problems to beekeepers, because they plunder the hives," said researcher Manfred Ayasse of the University of Ulm in Germany, in discussing his published research (see above). "Besides this, their ravages of fruit crops make hornets a serious pest to man. Our results could be used to develop environmentally responsible traps for pest hornets."
