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. 
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.
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.
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.

It is suggested that a signal from the host plant is essential to trigger the release of PBAN to induce pheromone production.
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.
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.
Physiological control of calling, pheromone release, and pheromone production in the female gypsy moth, Lymantria dispar
Air-borne collection from females and glandular titer determinations, and calls behavior, and allatectomy and nerve transection : Calling behavior and TAG morphology are studied.


Insect Mating Behavior: Endocrine Control of a Chemical Communication System
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.
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".
Sex Pheromones of Noctuid Moths. XVI. The Morphology of the Female Sex Pheromone Glands of Eight Species
In Autographa californica (Speyer), Pseudoplusia includens (Walker), and Rachiplusia ou (Guenee) (Plusiinae) the female sex pheromone gland is situated dorsally in the intersegmental membrane between
Behavior of the Imago of the Corn Earworm, Heliothis Zea (Boddie), with Special Reference to Emergence and Reproduction
The emergence and wing expansion of the imago is described. A villous surface from which the imago could hang was necessary for proper expansion and drying of the wings. 94.6 per cent of emergence
Trace Chemicals: The Essence of Sexual Communication Systems in Heliothis Species
Analysis of heptane-soluble compounds from ovipositors of Heliothis zea and Heliothis virescens shows that both species produce relatively large amounts of (Z)-11-hexadecenal, with traces of
Endocrine Control of Feniale Receptivity in Leucophaea maderae (Blattaria)
Allatectomized females of Leucophaea maderae (F.) do not accept courting males as readily as do normal females. It is concluded that normally the female's receptivity to courting males is influenced
Starvation-Induced Activity in Cockroach Malpighian Tubules
Adult male American cockroaches, Periplaneta americana (L.), normally yield inactive gut and malpighian tubule preparations; however, after 3½ days of starvation the activity of isolated malpighian
