Web20. mar 2024 · Sex pheromone molecules in the air are first adsorbed on the cuticular surface of olfactory sensilla, diffuse in the cuticular wax layer, and then enter inside olfactory sensilla through olfactory pores (Kaissling 1987 ). Sex pheromones are normally highly hydrophobic and difficult to dissolve into sensillum lymph. WebThe pheromone titer per female ranged from 50 to 200 ng. On the basis of a high-resolution mass spectrum the empirical formula of the pure isolated pheromone molecule was determined to be C 13 H 20 O 3. The pheromone was further defined by its Chromatographic behavior and spectroscopic properties. lightroom classic rotate image
