Role of Insect Sex Pheromone in Mating Behavior. II. An Aspect of Sex Pheromone as a Volatile Material

Abstract

The saturated vapor pressures of three compounds identified as a sex pheromone of Lepidoptera and related compounds are measured by the “gas-saturation method.” The values of saturated vapor pressure of these materials are 10-4 –10-1 mmHg at 30°C. Vapor-liquid equilibrium of these pheromonal compounds is discussed in regard to these values for vapor pressure and mole fraction (or weight %). © 1978, JAPANESE SOCIETY OF APPLIED ENTOMOLOGY AND ZOOLOGY.
