(Z)-11-HEXADECEN-1-OL: A BEHAVIORAL MODIFYING CHEMICAL PRESENT IN THE PHEROMONE GLAND OF FEMALE HELIOTHIS ZEA (LEPIDOPTERA: NOCTUIDAE)

Abstract
Fourteen and 16 carbon saturated and monounsaturated aldehydes have been identified as sex pheromone components for the four. species of Heliothis studied to date (Nesbitt et al. 1979; Klun et al. 1979; Teal et al. 1981). With the exception of H. zea (Boddie), the alcohol corresponding to the major aldehyde component, (Z)-1 l-hexadecen- 1-ol (Zl l-16:OH), also has been found in pheromone gland extracts of all species. We report here the identification of Zll-16:OH from pheromone gland extracts of H. zea females and the results of field trapping studies used to assess the behavioral effects of this compound on conspecific males.
