Perception of the female sex pheromone in Utetheisa ornatrix (Lepidoptera: Arctiidae) is responsible for induction and adjustment of calling by females and the collective phenomenon termed “female pheromonal chorusing”. We found five olfactory-active compounds in the U. ornatrix female gland. When females were exposed to the entire pheromone or to two of its (synthetically prepared) components, (Z,Z,Z)-3,6,9-eicosatriene and (Z,Z,Z)-3,6,9-heneicosatriene, they were more likely to call during a… 

Electrophysiological and Behavioral Responses of Female Beet Armyworm Spodoptera exigua (Hübner) to the Conspecific Female Sex Pheromone

Electroantennogram (EAG) recordings showed that female Spodoptera exigua can detect their own sex pheromones (two single components and their mixture), displaying a similar dose–response pattern to

Identification and Biosynthetic Studies of the Hydrocarbon Sex Pheromone in Utetheisa ornatrix

Analysis of Utetheisa ornatrix females by gas chromatography-mass spectrometry and measurement of responses of male moths by coupled gas Chromatography-electroantennogram detection confirmed the presence of large amounts of (Z,Z, Z)-1,3,6,9-heneicosatetraene (1,4,6-9-21:Hy) and smaller amounts of 2,2,2-2,3-2-3,2

Differential Octopaminergic Modulation of Olfactory Receptor Neuron Responses to Sex Pheromones in Heliothis virescens

Results indicate that octopamine plays a significant modulatory role in female sex pheromone detection in female moths; and that male and female pherOMone detection neurons share distinct pharmacological and physiological similarities in H. virescens despite sexual dimorphism at the antennal level.

Pheromone Autodetection: Evidence and Implications

Electrophysiological and behavioral investigations, as well as expression patterns of proteins involved in pheromone autodetection are included and problems inherent in defining a boundary between sex and aggregation phersomones considering the occurrence of autodETection are discussed.

Male Pheromones in Moths

  • Biology
  • 2016
This chapter will begin with a discussion of the genetic architecture of sex determination in Lepidoptera and how it predisposes males to extravagance, and the benefits accrued by females who exercise mate choice based on male courtship pheromones.

Non-Host Plant Volatiles Disrupt Sex Pheromone Communication in a Specialist Herbivore

It is suggested that disruption of both phersomone emission and orientation to sex pheromone may explain, at least in part, an observed reduction in herbivore attack in polyculture compared with monoculture plantings.

Pheromone production, male abundance, body size, and the evolution of elaborate antennae in moths

Among species with elaborate antennae, longer antennae were typically associated with lower male abundances and pheromone compounds with lower molecular weight, suggesting that male distribution and a more rapidly diffusing female sex phersomone may influence the size but not the general shape of male antennae.

Calling Behavior of Tetropium fuscum (Coleoptera: Cerambycidae: Spondylidinae)

It is demonstrated, using solid-phase micro-extraction and gas chromatography — mass spectrometry, that this posture is positively correlated with the release of fuscumol, a male-produced long-range pheromone, and that the presence of conspecific males stimulates calling behaviour in T. fuscUM.


It is suggested that female signaling for males using sex pheromones bears a cost and thus calling may serve as honest advertisement for female quality.



Autodetection and chemistry of female and male pheromone in both sexes of the tiger moth Panaxia quadripunctaria

Females of Panaxia quadripunctaria PODA are capable of pheromone autodetection in contrast to the majority of moths where females are considered to be anosmic for their own attractant.

Female pheromonal chorusing in an arctiid moth, Utetheisa ornatrix

An unusual case of communal sexual display in the arctiid moth Utetheisa ornatrix is reported that is designated "female pheromonal chorusing", and it is argued that this biased sex ratio generates intrasexual competition among females, to which they respond by elevating signaling effort such that the likelihood of at least matching their neighbors' signals is increased.

Sex attractant of an arctiid moth (Utetheisa ornatrix): A pulsed chemical signal

It is argued that such temporal patterning — which had not previously been demonstrated for an airborne chemical signal — can provide close-range orientation cues to the male moth as it seeks out the female.

Pheromonal advertisement of a nuptial gift by a male moth (Utetheisa ornatrix).

By mating preferentially with males endowed with hydroxydanaidal, females may ensure their acquisition of an alkaloidal gift for use in egg defense and communicate their possession of protective alkaloids and their capacity to provision the female.

Male and Female Antennal Responses in Heliothis virescens and H. subflexa to Conspecific and Heterospecific Sex Pheromone Compounds

The hypothesis that autodetection of sex pheromones occurs in females of both H. virescens and H. subflexa is supported, although whether females behaviorally respond to any, or to combinations, of these compounds remains to be elucidated.

Host plant volatiles synergize responses of sex pheromone-specific olfactory receptor neurons in male Helicoverpa zea

Electrophysiological recordings were obtained from olfactory receptor neurons in antennal trichoid sensilla of male corn earworm and confirmed that the enhanced impulses originated from the pheromone-component-tuned neuron.

Physiology and glomerular projections of olfactory receptor neurons on the antenna of female Heliothis virescens (Lepidoptera: Noctuidae) responsive to behaviorally relevant odors

Terminal arborizations from sensillar types containing olfactory receptor neurons sensitive to male hairpencil components and plant volatiles were also localized to distinct glomerular locations, providing insight into the representation of behaviorally relevant odorants in the female moth Olfactory system.

The alteration of calling behaviour by female Choristoneura fumiferana when exposed to synthetic sex pheromone

The calling behaviour of 0‐day‐old and 2‐day‐old virgin female eastern spruce budworm moths, Choristoneura fumiferana (Clem.) was observed during exposure to different concentrations of the synthetic

Responses of olfactory receptor neurons in Utetheisa ornatrix to gender-specific odors

Electrophysiological responses of individual olfactory receptor neurons in sensilla trichodea on the antennae of adult arctiid moths, Utetheisa ornatrix, to stimulation with volatiles associated with both sexes are recorded.
