SummaryThe capture of adult male moths in female sex pheromone traps of two key agricultural pests, the corn earworm (Helicoverpa zea) and the codling moth (Cydia pomonella), is enhanced or synergized by a certain group of host-plant volatiles, the “green-leaf volatiles” (GLVs). Since female adults of both species call and release their sex pheromones while perched upon the leaves of their host-plants, the volatile constituents from the leaves of a number of host-plants were compared.

Host Plant Volatiles Synergize Response to Sex Pheromone in Codling Moth, Cydia pomonella
TLDR
Plant volatile compounds synergize attraction of codling moth males Cydia pomonella to sex pheromone (E,E)-8,10-dodecadien-1-ol (codlemone) with a strong antagonistic effect when blended in a 1:10,000 ratio with codlemone.
Interactions Between Host-plant Volatiles and the Sex Pheromones of the Bird Cherry-oat Aphid, Rhopalosiphum padi and the Damson-hop Aphid, Phorodon humuli
TLDR
The hypothesis that specific plant volatiles synergize responses of autumn migrating aphids to their sex pheromone is supported, which may be important in allowing males to discriminate between conspecific sexual females (oviparae) and those of other aphid species.
Monitoring Grape Berry Moth (Paralobesia viteana: Lepidoptera) in Commercial Vineyards using a Host Plant Based Synthetic Lure
TLDR
There was a significant positive correlation between captured males and females on panel traps although not between females captured onpanel traps and males captured in pheromone-baited traps for both years suggesting phersomone traps do not accurately reflect either female or male activity.
Enhancement of Attraction to Sex Pheromones of Spodoptera exigua by Volatile Compounds Produced by Host Plants
TLDR
The results suggest that some host plant volatiles enhance the orientation response of S. exigua male moths to sex pheromone sources.
Exploring the Effects of Plant Odors, from Tree Species of Differing Host Quality, on the Response of Lymantria dispar Males to Female Sex Pheromones
TLDR
This work explored the behavior of L. dispar males towards sexual pheromone in the presence and absence of plant volatiles and their ability to discriminate between two plant species with different degrees of suitability for their offspring: a suboptimal host (Pinus sylvestris), and an optimal host (Quercus robur).
State-Dependent Plasticity in Response to Host-Plant Volatiles in a Long-Lived Moth, Caloptilia fraxinella (Lepidoptera: Gracillariidae)
TLDR
Antennal responses to host plant volatiles were plastic and depended on moth physiological state, and were highest when moths were reproductively active and would be seeking oviposition hosts, and there was no increase in behavioral response to sex pheromone in the presence of an ash host.
A Challenge for a Male Noctuid Moth? Discerning the Female Sex Pheromone against the Background of Plant Volatiles
TLDR
The results lead to the conclusion that pheromone-plant interactions in Heliothis virescens might be an effect of stimulation with supra-natural plant odor concentrations, whereas under more natural conditions the olfactory system of the male moth appears to be well adapted to follow the female phersomone plume without interference from plant-emitted odors.
Plant volatiles affect oviposition by codling moths
TLDR
Oviposition in wild codling moth females, collected as overwintering larvae from apple, pear and walnut, was stimulated by volatiles from fruit-bearing green branches of these respective hostplants, suggesting a considerable plasticity in the female response to host plant odours.
Plant odor and sex pheromone are integral elements of specific mate recognition in an insect herbivore
TLDR
That plant cues enhance discrimination of sex pheromone quality confirms the idea that specific mate recognition in noctuid moths has evolved in concert with adaptation to host plants.
Short-chain alkanes synergise responses of moth pests to their sex pheromones.
TLDR
The findings show the promise of using short-chain alkanes as pheromone synergists for mating disruption of insect pests of food crops.

Green leaf volatiles enhance sex attractant pheromone of the tobacco budworm,Heliothis virescens (Lep.: Noctuidae)
TLDR
Components of the green leaf volatile complex were shown to enhance responses of tobacco budworm, Heliothis virescens, males to the sex attractant pheromone of conspecific females in the field.
Male moth sensitivity to multicomponent pheromones: Critical role of female-released blend in determining the functional role of components and active space of the pheromone
TLDR
The results support the concept that minor components function to enhance male sensitivity to the pheromone, and the specificity of the signal, and show that males initiated upwind flight in significantly higher percentages to the complete blends of components, at all dosages, compared to single components or partial blends.
Green leaf volatiles enhance aggregation pheromone of boll weevil, Anthonomus grandis
TLDR
The combined electrophysiological and field data support ‘across‐fiber coding’ of green leaf volatiles by boll weevil olfactory receptors.
An aggregation pheromone of Sitona lineatus
TLDR
A male-produced aggregation attractant is reported, the first demonstration of pheromonal communication by this weevil, and shows clearly that 4-methyl-3,5-heptanedione attracts both sexes.
Some Aspects of the Mating and Oviposition Behavior of the Codling Moth, Carpocapsa pomonella
TLDR
Dissection of field-captured codling moths from black-light traps revealed that more than 90% of the females attracted to the black light were ready to oviposit or were reproductively young, suggesting that blacklight traps are more efficient than bait pans for the timing of codling moth sprays.
Analysis of Pheromone-Mediated Behaviors in Male Grapholitha molesta, the Oriental Fruit Moth (Lepidoptera: Tortricidae)
TLDR
There was a strong correlation between pheromone plume behaviors of pre-flight wing fanning while walking and upwind flight, suggesting that these behaviors may be closely associated, functioning to locate the pherOMone source by ground or air, respectively.
Nocturnal Behavior of Four Lepidopteran Pests That Attack Tobacco and Other Crops
TLDR
Ambient air and dew point temperatures, night brightness, wind speed, and relative humidity were recorded in an attempt to relate these meteorological parameters to moth behavior, and the general pattern of moth activity indicates early evening and early morning peaks of feeding interspersed with oviposition.
Physiology of interspecific chemical communication in Heliothis moths
TLDR
Electroantennograms recorded from the antennae of adult male and female corn earworms provide a physiological basis by which H.zea males can distinguish the interspecific repellent from the conspecific pheromone blend and are likely to contribute to reproductive isolation between these two species.
Isolation and identification of volatiles in the foliage of potato,Solanum tuberosum, a host plant of the colorado beetle,Leptinotarsa decemlineata
TLDR
These leaf volatiles constitute a general green leaf volatile complex, being active in the olfactory orientation of the Colorado beetle and as such are probably of importance to various phytophagous insects.
Attraction of male gypsy and nun moths to disparlure and some of its chemical analogues
TLDR
These experiments support the assumption that disparlure is also at least part of the sexual attractant of the nun moth, and no masking of the electrophysiological response was observed with the receptor cells when the olefin was added to disparlures.
