Essential smell gene may provide key to new insect repellents
... of insects, including locusts, mosquitoes, moths, honeybees and medflies. "In all of these insects the gene is found in nearly all the olfactory neurons. The vast majority of cells responsible for smell have it," says Vosshall. This is surprising because insects have evolved smell receptors tailored to their ...Espionage may have driven the evolution of bee language according to UCSD-led study in Brazil

... Kakugo, that could only be found in the brains of honeybees that displayed aggressive behavior toward a hornet decoy. They believe that the RNA is an indicator of a viral infection. "These results demonstrate that Kakugo RNA is a plus-strand RNA of a novel picorna-like virus and that the brains of aggress...Pew report finds GM insects may offer benefits, but clear regulatory oversight is lacking

All of these uncertainties will need to be addressed by regulators prior to the introduction and release of GM insects.

...tract representations to communicate. For example, honeybees use a "waggle dance" in which a returning forager bee runs up and down the honeycombs and shakes her abdomen to communicate distance and direction to a food source. Honeybees communicate within the nest how to get to the food source and do not leave ...Stem cells isolated from monkey eggs continue producing variety of other cells
