Title: Pheromones of social bees
Description: Pheromones are chemical substances generated by bees and other animals as sex attractants, alarm signals, trail markers, and regulatory agents. Because of the economic importance and intrinsic interest of social bees, their pheromones have been among the most studied, and many noteworthy discoveries have recently been made.<p> 
This book summarizes research on bee pheromones — mostly those of honeybees —- focusing on work done at Rothamsted Experimental Station in England, a leading center for bee study.<p>
John Free has divided his book according to pheromone function, covering such subjects as communication of a queen's presence, inhibitory effects of queens and queen rearing, control of worker ovary development, and stimulatory effects of queen pheromone. He also treats laying workers, brood pheromone, comb pheromone, regulation of drone population, mating pheromones, nest and nest-mate recognition, trail and foraging pheromones, Nasonov pheromone, and alarm and aggression pheromone.<p>
The author thoroughly evaluates the present state of knowledge of pheromones and suggests further lines of inquiry. He discusses ways in which synthetic chemicals are being and might be used to increase beekeeping efficiency, and he includes a chapter on their economic potential.
The first comprehensive volume on this subject, Pheromones of Social Bees will be of interest to animal behaviorists and ecologists, as well as to those concerned with apiculture and crop pollination.
