Plant volatile compounds synergize attraction of codling moth males Cydia pomonella to sex pheromone (E,E)-8,10-dodecadien-1-ol (codlemone). Several apple volatiles, known to elicit a strong antennal response, were tested in a wind tunnel. Two-component blends of 1 pg/min codlemone and 100 pg/min of either racemic linalool, (E)-β-farnesene, or (Z)-3-hexen-1-ol attracted significantly more males to the source than codlemone alone (60, 58, 56, and 37%, respectively). In comparison, a blend of… Expand
Plant Volatiles Enhance Behavioral Responses of Grapevine Moth Males, Lobesia botrana to Sex Pheromone
TLDR
The results highlight the role of plant volatiles in the sensory ecology of L. botrana and suggest an optimal release ratio of 1:1000 (sex pheromone: host plant volatile). Expand
Plant volatile compounds shorten reaction time and enhance attraction of the codling moth (Cydia pomonella) to codlemone
TLDR
Adding R(+)-limonene, linalool, (E)-β-farnesene or ethyl (E, Z)-2,4-decadienoate to codlemone significantly increases the proportion of males flying to the pheromone source in a wind tunnel, and would enhance mating disruption through better engagement of males with dispensers, to the detriment of females. Expand
Synergism and redundancy in a plant volatile blend attracting grapevine moth females.
TLDR
The observed behavioral plasticity in response to grape volatile blends probably reflects the variation of the natural plant signal, since females oviposit on different grape varieties, in different phenological stages. Expand
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. Expand
The synergistic attractiveness effect of plant volatiles to sex pheromones in a moth
TLDR
The results indicated that benzaldehyde, phenylacetaldehyde, and benzyl alcohol significantly enhanced, and longifolene, (E)-β-caryophyllene, and (E-β-ocimene had no significant effect on the attractions to SPs, whereas racemic linalool significantly decreased the attraction of male S. litura moths to SPS throughout the olfactory pathway. Expand
Host plant volatiles serve to increase the response of male European grape berry moths, Eupoecilia ambiguella, to their sex pheromone
TLDR
Time–event analysis indicates a positive correlation between faster activation and probability of source contact by the responding males, suggesting that perception of host plant products with the sex pheromone facilitates male E. ambiguella to locate females on host plants, lending credence to the hypothesis that plant products can signal rendezvous sites suitable for mating. Expand
Host plant volatiles induce oriented flight behaviour in male European grapevine moths, Lobesia botrana.
TLDR
Grapevine moth males perceive and respond to host plant volatiles at biologically relevant levels indicating that host plantvolatiles figure as olfactory cues and that L. botrana males can discern places where the likelihood of encountering females is higher. Expand
Pheromone pre‐exposure and mating modulate codling moth (Lepidoptera: Tortricidae) response to host plant volatiles
TLDR
Wind tunnel experiments confirmed that pre‐exposure to sex pheromone codlemone increased the behavioural response of codling moth males to pear ester, which supports the idea that male attraction to the plant volatile pear Ester and sex phersomonecodlemone is mediated through the same sensory channels. Expand
Responses to sex pheromone and plant odours by olfactory receptor neurons housed in sensilla auricillica of the codling moth, Cydia pomonella (Lepidoptera: Tortricidae).
TLDR
A scanning electron microscopic study of the antennae of both sexes supported an earlier study, apart from that long s.trichodea were present in a wreath at the proximal margin of the flagellomere and in addition evenly distributed over the remaining surface, and a previously non-described sensillum type with external basiconic features was revealed. Expand
Monitoring codling moth (Lepidoptera: Tortricidae) with a four‐component volatile blend compared to a sex pheromone‐based blend
TLDR
It is shown that codling moth can be trapped effectively in apple under MD without the use of sex pheromone lures, and efforts to improve spray timings and action threshold determinations as well as mass trapping might be enhanced with this new lure. Expand

Host-plant green-leaf volatiles synergize the synthetic sex pheromones of the corn earworm and codling moth (Lepidoptera)
TLDR
It appears that these green-leaf volatiles act as pheromone synergists which increase or enhance the attraction or arrestment of male moths in phersomone traps. Expand
Identification of further sex pheromone synergists in the codling moth, Cydia pomonella
TLDR
Pheromone gland extracts of codling moth females were examined by gas chromatography coupled with mass spectrometry and electroantennography and addition of dodecanol augmented male attraction to codlemone at the proportions found in female glands. Expand
Host plant volatiles synergize responses of sex pheromone-specific olfactory receptor neurons in male Helicoverpa zea
TLDR
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. Expand
Behavioral observations of codling moth, Cydia pomonella, in orchards permeated with synthetic pheromone
TLDR
Reducing pheromone concentrations towards the upper part of the tree canopy, together with the stimulation of male flight activity by synthetic phersomone explains failures to control codling moth at high population density with current dispenser formulations. Expand
Plant odor analysis of apple: antennal response of codling moth females to apple volatiles during phenological development.
TLDR
The study of apple volatiles eliciting an antennal response, together with a survey of the seasonal change in the release of these compounds, is the first step toward the identification of volatile mediating host-finding and oviposition in codling moth females. Expand
Attraction of codling moth males to apple volatiles
TLDR
The attraction of the codling moth, Cydia pomonella, to apple volatile compounds known to elicit an antennal response was tested both in the field and in a wind tunnel, and the addition of (E,E)‐α‐farnesene to (E), which had a synergistic effect on male attraction. Expand
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. IncreasedExpand
Sex pheromone blend of the codling moth,Cydia pomonella: Evidence for a behavioral role of dodecan-1-ol
TLDR
Pheromone glands and effluvia of the codling moth female contain E-8, E-10-dodecadien-1-ol as main component, accompanied by its geometric isomers, the corresponding acetate and aldehyde and saturated alcohols of 10 to 18 carbons. Expand
A pear-derived kairomone with pheromonal potency that attracts male and female codling moth, Cydia pomonella (L.)
TLDR
The particular attribute of attracting CM females renders this kairomone a novel tool for monitoring population flight and mating–ovipositional status, and potentially a major new weapon for directly controlling CM populations. Expand

TLDR
The gland titer and release of sex pheromone was studied in individual Cydia pomonella females and addition of these minor components to codlemone did not increase male attraction to field traps. Expand
