Sex pheromone production in the female corn earworm moth Heliothis zea is controlled by a hormonal substance produced in the female's brain. It is present in the brain in scotophase as well as photophase, but it is released into the hemolymph to stimulate pheromone production only in the scotophase. The stimulatory activity was also detected in the brains of male corn earworm moths and of other moths. 

Topics from this paper

Endogenous suppression of pheromone production in virgin female moths
It is found that even in virgin Heliothis zea females the titer of pheromone declines after the third night of adult life, although the number of eggs laid increases, and a substance present in the bursa, ovaries and hemolymph of senescing virgins suppresses pherOMone production. Expand
Identification of a Neuropeptide Hormone That Regulates Sex Pheromone Production in Female Moths
A pheromone biosynthesis activating neuropeptide (PBAN) hormone was identified from the brain-subesophageal ganglion complexes of the adult corn earworm, Heliothis zea, and induced production of a normal quantity of sex pherOMone in ligated H. zea females, indicating that this or similar peptides may be responsible for the regulation of phersomone production in moths. Expand
Neurohormonal Regulation of Pheromone Biosynthesis in Heliothis Zea: Evidence for Multiple Forms of the Hormone
Females of the corn earworm, Heliothis zea, produce the sex pheromone only during the scotophase, and the factor has recently been characterized as a neuropeptide hormone originating in the suboesophageal ganglion (SOG) and released through the corpora cardiaca into the hemolymph to activate phersomone production.

Juvenile hormone stimulates pheromonotropic brain factor release in the female black cutworm, Agrotis ipsilon
Results indicate that JH secreted by CA control sex pheromone biosynthesis of A. ipsilon females by stimulating pheromonotropic brain factor (PBAN- like factor) release from the central nervous system and not by controlling PBAN-like production or by priming PBAN -like target glandular cells. Expand
Hormonal control of pheromone responsiveness in the male black cutwormAgrotis ipsilon
It is suggested that reproductive processes are synchronized in males and females through endocrine control; timing of the mating activity could serve as an adaptive strategy linked to the migratory behaviour of this species. Expand
Stimulation of Sex Pheromone Production in Corn Earworm Moths by Injection of Extracts of Heads of Males of the Caribbean Fruit Fly
Females of the Corn earworm moth were induced to produce sex pheromone during the photophase by injection of aqueous extracts obtained from the heads of sexually mature males of the Caribbean fruit fly, Anastrepha suspensa (Loew). Expand

It is suggested that a signal from the host plant is essential to trigger the release of PBAN to induce pheromone production. Expand
Regulation of pheromone production in the gypsy moth, Lymantria dispar, and development of an in vivo bioassay
Administration of pheromonotropic factors to the posterior cut-end of VNC can be used as a bioassay for the gypsy moth and possibly for other species in which these factors are transported via the VNC. Expand
Hormonal control of egg maturation in the corn earworm, Heliothis zea
The results indicate that egg maturation is controlled by JH and that continuous input from the brain is required for sustained CA activity for maintaining a high rates of egg m maturity. Expand
Stimulation of sex pheromone production by PBAN-like substance in the pine caterpillar moth, Dendrolimus punctatus (Lepidoptera: Lasiocampidae).
Sex pheromone production in the female pine caterpillar moth, Dendrolimus punctatus is controlled by a PBAN-like substance located in the head of female moth, which indicates that females are capable of producing four oxygenated functional groups. Expand

Experiments on several species of moths and cockroaches indicate that the production of sex pheromone in virgin females is under endocrine control in some species but not in others. Expand

Evidence suggestive of a role for the brain in the post imaginal molt reactivation of the corpora allata is presented, and the female reproductive cycle of Byrsotria is discussed in the light of this new information. Expand

Inhibition of reproductive processes owing to pregnancy was partially overcome by injecting relatively large dosages of hormone mixtures, although pheromone production was slight and sporadic. Expand
Role of the corpora cardiaca in the behavior of saturniid moths. I. Release of sex pheromone.
In virgin female silkmoths the protrusion of the genitalia or "calling" behavior signals sex pheromone release and removal of the corpora allata-corpora cardiaca complex greatly reduces the number of moths which "call". Expand
