This 25th anniversary edition, updated by the author, reveals the miraculous communication systems present in nature. Learn how plants and insects communicate through emissions in the infrared frequency range and why poisonous pesticides do not solve the real problems facing agriculture. In this breakthrough book Phil Callahan uncovers why certain insects are attracted only to certain plants, the role of pheromones work in nature, and how plants under stress literally signal insects to come devour them. Long out of print . . . classic Callahan!
