| Abstract: | "Several physico-chemical properties of the female sex pheromone of the beet cyst nematode Heterodera schachtii were elucidated. At least one component of the pheromone can be extracted from aqueous solutions with diethyl ether. However, the pheromone has a higher solubility in water, as most of the pheromone activity remained in the water fraction. Ion exchange chromatography revealed that the pheromone or at least one of its components is positively charged, whereas another pheromone component may be negatively charged. Fractional distillation of pheromone extracts showed that it is, indeed, composed of at least two components. These components may interact additively rather than synergistically" |
