“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,...
They Deal with Scents
World-renowned organic chemist Wittko Francke (second from right) met with UC Davis researchers following his presentation on Wednesday at a UC Davis Department of Entomology seminar.

Walnuts are packed with vitamins, minerals and antioxidants, right?
And sometimes a little protein.
Protein, as in larvae. That's not a welcome sight.
Sometimes you'll find two or three navel orangeworm (NOW) larvae inside a single walnut,...

In a Nutshell
IN A NUTSHELL!--Close-up of larva inside a walnut. You can tell if it's a navel orangeworm (NOW) if it has a crescent-shaped marking on the sides of the second segment behind the head, says UC Davis entomologist Frank Zalom. Often, with NOW, there are two or more larvae inside a single nut. (Photo by Kathy Keatley Garvey)
Chemical ecologists at the University of California, Davis, are changing their navel-orangeworm research direction after an elementary school student’s science project found that the major agricultural pest prefers pistachios over almonds and...
