In the phytophagous corn earworm, Helicoverpa (Heliothis) zea, females delay their reproductive behaviors until they find a suitable host on which to deposit their eggs. Perception of volatile chemical signals from corn silk triggers the production of sex pheromone followed by its release, which leads to mating. Several natural corn silk volatiles, including the plant hormone ethylene, induced pheromone production in H. zea females. Because H. zea larvae feed on the fruiting parts of a wide… 
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.
Host plant influences on sex pheromone behavior of phytophagous insects.
Host plant influences on insect sex pheromone communication may be important aspects of the formation of feeding and mating aggregations, of insect strategies to locate both hosts and mates, of behavioral reproductive isolation among sibling species, and of the regulation of reproduction to coincide with the availability of food and oviposition sites.
In most species of moths, female produce and release sex pheromones to attract conspecific males for mating, so the kairomonal interaction would be most likely to occur in species that are monophagous or oligophagyous, as postulated by Carde, 1984.
Botanical Volatiles Selection in Mediating Electrophysiological Responses and Reproductive Behaviors for the Fall Webworm Moth Hyphantria cunea
Initial evidence is provided showing that universal host-derived volatile cues are essential for H. cunea moth in terms of mating, which can also provide insights into the development of botanical attractants.
Pheromones in the Management of Major Lepidopterous and Coleopterous Pests of Cotton
Pheromones of major pests have been found to be effective, economic and eco-friendly in agro-ecosystems in which cotton is cultivated.
Effects of host plant,Gossypium hirsutum L., on sexual attraction of cabbage looper moths,Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae)
Unmated female or male cabbage looper moths,Trichoplusia ni (Hübner), were attracted more often in a flight tunnel to a cage with moths of the opposite sex and a bouquet of cotton foliage. Increased
Sexual behaviour of the green capsid bug
It is shown that long-range mate location by means of a sex pheromone is only part of the sexual behaviour of the green capsid bug, which is an unpredictable pest in fruit orchards in North-Western Europe and an efficient monitoring system to predict bug damage in an orchard may reduce the use of insectices.
Proximate Mechanisms of Host Plant Location by a Specialist Phytophagous Insect, the Grape Berry Moth, Paralobesia Viteana
The results of this study support a hypothesis that GBM females are using volatile blends to locate a favorable habitat rather than a specific host plant, and that discrimination is occurring within the habitat, or even post-landing.


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.
Trans-2-Hexenal: Mating Stimulant for Polyphemus Moths
The volatile compound from oak leaves which stimulates the female polyphemus moth to release her sex pheromone has been isolated and identified as trans-2-hexenal. Although leaves of other food

Ag(I), applied foliarly as AgNO(3), effectively blocked the ability of exogenously applied ethylene to elicit the classical "triple" response in intact etiolated peas and should prove useful in defining further the role of ethylene in plant growth.
Role of Early-Season Wild and Naturalized Host Plants in the Buildup of the F 1 Generation of Heliothis zea and H. virescens in the Delta of Mississippi
Surveys from 1965 to 1977 of the native wild and introduced naturalized flora of the delta of Mississippi for F1 generation larvae of the overwintered population of Heliothis zea (Boddie) and H.
Odorant-binding-protein subfamilies associate with distinct classes of olfactory receptor neurons in insects.
The association of different insect OBP subfamilies with distinct classes of olfactory neurons having different odorant specificities suggests that OBPs can act as selective signal filters, peripheral to the actual receptor proteins.

Molecular requirements for the biological activity of ethylene.
The molecular requirements for ethylene action were investigated using the pea straight growth test and it is suggested that CO(2) delays fruit ripening by displacing the ripening hormone, ethylene, from its receptor site.
