A honey bee becomes a royal queen or a common worker as a result of the food she receives as a larva. While it has been well established that royal jelly is the diet that makes bees queens, the molecular path from food to queen is still in dispute. However, scientists at Arizona State University, led by Adam Dolezal and Gro Amdam, have helped reconcile some of the conflicts about bee development and the role of insulin pathways and partner proteins. Their article "IIS and TOR...

Just as raging hormones are part of the process of a child's maturation through the teen years to adulthood, juvenile hormones, a group of insect isoprenoids, play an important role as butterflies, fruit flies and mosquitoes transform their body structures as they molt from larva to pupa and then adults. Unlike humans, in insects the juvenile hormone inhibits development of adult characteristics until the insects reach a proper stage. Juvenile hormones also play a prominent role in regulating...

What makes a bee grow up to be a queen? Scientists have long pondered this mystery. Now, researchers in the School of Life Sciences at Arizona State University have fit a new piece into the puzzle of bee development. Their work not only adds to understanding about bees, but also adds insights into our own development and aging. The study, which appeared in the June 30 online edition of Biology Letters, shows that a key protein in the insulin signaling pathway plays a strong role in caste...

Prior to coming to Nevada 16 years ago, David Schooley was a key figure at a small company in Palo Alto, Calif. that developed methoprene, an insecticide that halts the maturation of insect larvae to adults.       Methoprene, which has the same effect as an insect hormone called juvenile hormone, also stops the insect from reproducing. It is being used heavily throughout the United States to help prevent the spread of West Nile Virus. Schooley's contribution to the...
