    Notes: Abstract Each of the four compounds that have been identified from sex pheromone glands ofHeliothis zea female moths was examined for its ability to elicit sexual responses from male moths in a flight tunnel. Males flew upwind to (Z)-11-hexadecenal alone, but greater levels of behavioral activity were evoked with the addition of (Z)-9-hexadecenal to the treatment. Addition of hexadecanal or (Z)-7-hexadecenal to the initial two components had no effect in raising the behavioral response of the males in the flight tunnel whether added singularly at both the normal gland-emission ratio or at varying ratios or in combination at the normal ratio. Live, calling females elicited levels of sexual activity from males not significantly different from that elicited by the mixture of (Z)-11- and (Z)-9-hexadecenal on cotton wicks.

    Influence of Age on Antennal Response of Male Honey Bees, Apis mellifera, to Queen Mandibular Pheromone and Alarm Pheromone Component (1997)
    Springer
    Journal of chemical ecology 23 (1997), S. 1867-1880 
    Details
    ISSN: 1573-1561
    Keywords: Apis mellifera honey bee ; drone bees ; electroantennogram ; queen pheromone ; alarm pheromone

    Notes: Abstract Using a computer-controlled pheromone-puff delivery system with signal averaging, we investigated the change with age of the electroantennogram (EAG) response of drone (male) honey bees to queen mandibular pheromone (QMP) and an alarm pheromone component, isopentyl acetate (IPA). Drone antennae were significantly more sensitive than worker antennae to QMP, but there was no significant difference in response to IPA. Response to QMP was dose dependent and decreased gradually with the age of the drone. Drone response to IPA did not diminish significantly with age. Drones do not mature sexually or make their first flights until about 1 week old, so the ontogeny of their sensory responsiveness to queen pheromones does not reflect that of their behavior. It is unknown if drones exhibit any behavioral response to IPA. The signal-averaging system we describe could be used to improve resolution of low signal-to-noise ratio signals in other EAG studies.

    Alarm pheromone perception in honey bees is decreased by smoke (Hymenoptera: Apidae) (1995)
    Springer
    Journal of insect behavior 8 (1995), S. 11-18 
    Details
    ISSN: 1572-8889
    Keywords: honey bee ; Apis mellifera ; alarm pheromone ; electroantennograph
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Abstract The application of smoke to honey bee(Apis mellifera) antennae reduced the subsequent electroantennograph response of the antennae to honey bee alarm pheromones, isopentyl acetate, and 2-heptanone. This effect was reversible, and the responsiveness of antennae gradually returned to that of controls within 10–20 min. A similar effect occurred with a floral odor, phenylacetaldehyde, suggesting that smoke interferes with olfaction generally, rather than specifically with honey bee alarm pheromones. A reduction in peripheral sensitivity appears to be one component of the mechanism by which smoke reduces nest defense behavior of honey bees.

    Behavioral responses of maleHeliothis virescens in a sustained-flight tunnel to combinations of seven compounds identified from female sex pheromone glands (1983)

    Notes: Abstract Each of the seven compounds that have been identified from femaleHeliothis virescens sex pheromone glands was examined for its ability to elicit sexual responses from male moths in a flight tunnel. The two compounds initially described as pheromone components, (itZ)-11-hexadecenal and (itZ)-9-tetradecenal, were necessary for behavioral activity to occur. Of the remaining five compounds, hexadecanal was most consistent in elevating behavioral activity of males when it was added to treatments. Live, calling females elicited greater sexual activity from males than did the 7-compound mixture on rubber septa.
