In the Thick of Fruit Flies

Roger Vargas

Roger Vargas is in the thick of fruit-fly research and he probably wishes those insects would thin out. He's a research entomologist at the USDA-ARS Pacific Basin Agricultural Research Center in Hilo, Hawaii.  For those who don't deal with acronyms,...

Not a Failure to Communicate

Mulberry Tree

The female silkworm moth releases a sex pheromone, bombykol, that's very enticing to the male. He can detect it from miles away. Now researchers in the UC Davis Department of Entomology have discovered that the fruit fly has a native odorant receptor...

A FEMALE SILKWORM (left) releases a sex pheromone from an extruded gland in the abdominal tip. A male moth (right) detects the pheromone (bombykol) remotely with neurons housed in antennal sensilla. He responds immediately by wing fanning and moving in a zigzag pattern toward the calling female. (Photo by Samuel Woo, UC Davis).
