Not a Failure to Communicate

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...

Scent of a Female
Scent of a Female

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).
