Irresistible to their species
Scientists at the University of Toronto found that by genetically tweaking fruit flies so they failed to produce a particular type of pheromone or odour, it turned them irresistible to their species.

The real thing
Scientists were able to train the honeybees to associate two similar odors with different nectar rewards. The results left little doubt over what honeybees like to sip: soda-sweet nectar.
"Bees tend to like sugary solutions that are about equivalent to the concentration of sugar in Coca Cola (around 30 percent sucrose)," lead author Geraldine Wright told Discovery News.

The sea of odors
Although a flower's odor can be composed of hundreds of chemicals, a moth uses just a handful to recognize the flower.
It's like identifying a piece of music from hearing only the notes played by a few key instruments, said lead researcher Jeffrey A. Riffell.
[...] The finding provides insight into how the brain processes a specific smell from the sea of odors floating through the air.

Pheromones used to control vampire fish
US researchers deployed a laboratory version of a male sea lamprey pheromone to trick ovulating females into swimming upstream into traps.
The sea lamprey, sometimes dubbed the "vampire fish", has parasitised native species of the Great Lakes since its accidental introduction in the 1800s.
[...] This is thought to be the first time that pheromones have been shown to be the basis of a possible way of controlling animal pests other than insects.
