Abstract The total and relative amounts of (Z)-11-tetradecenyl acetate (Z11-14:Ac), (E)-11-tetradecenyl acetate (E11-14:Ac), (Z)-11-tetradecen-1-ol (Z11-14:OH) and (Z)-11-tetradecenal (Z11-14:Al), and the EAG response of male antennae to these pheromone gland compounds were compared in laboratory reared Choristoneura rosaceana Harris (Lepidoptera: Tortricidae) from British Columbia, Michigan, Ontario, New York, and Quebec. A field trapping experiment was conducted in each of these locations to… Expand
Isolation, Identification, Synthesis, and Field Evaluation of the Sex Pheromone of the Brazilian Population of Spodoptera frugiperda
TLDR
E7-12:Ac is an active component in the sex pheromone of the Brazilian populations of S. frugiperda, indicating that the Z7- 12:Ac + Z9-14: Ac + E7-11-16:Ac blend was significantly better than Z8-9-13-14 + E8-10-15:Ac blends. Expand
Relative Attractiveness of Incomplete and Complete Blends of Synthetic Pheromone to Male Obliquebanded Leafroller (Lepidoptera: Tortricidae) Moths in a Flight Tunnel and in Apple Orchards: Implications for Sex Pheromone–Mediated Mating Disruption of This Species
TLDR
The superior attractiveness of the four-compound pheromone compared with the major compound, or to the major compounds plus the minor compound E11–14:OAc, suggests that it would be the most effective synthetic phermone if competitive attraction were an important mechanism of disruption in this species.

Optimization of synthetic pheromone blend for use in monitoring Choristoneura rosaceana (Lepidoptera: Tortricidae) in Niagara peninsula, Ontario, apple orchards
Trapping experiments were carried out in Niagara peninsula, Ontario apple orchards to determine the optimum ratios of synthetic pheromone compounds for use in monitoring the obliquebanded leafroller,Expand

TLDR
The results suggest that the pheromonal response of the predominant endemic population of C. rosaceana in Minnesota is similar to theresponse of the pest in many parts of western North America. Expand
Examining disruption of pheromone communication in Choristoneura rosaceana and Pandemis limitata using microencapsulated (Z)‐11‐tetradecenyl acetate applied in a laboratory flight tunnel
TLDR
It appears possible to evaluate relative activity of MEC pheromones in a laboratory setting which may aid in development of new formulations for mating disruption, and disorientation was found to be dose‐dependent. Expand
Identification and Differential Expression of a Candidate Sex Pheromone Receptor in Natural Populations of Spodoptera litura
TLDR
It is inferred that variation in transcription levels of olfactory receptors may modulate sex pheromone perception in male moths and could affect both of pest control and monitoring efficiency by phersomone application after long time mass trapping with one particular ratio of blend in the field. Expand
Identification and field evaluation of the sex pheromone of a Brazilian population of Spodoptera cosmioides
TLDR
The sex pheromone components of Spodoptera cosmioides are Z9‑14:OAc and Z9,E12‑14OAc; they are important for conferring species specificity, and there is phersomone-mediated cross attraction between S. frugiperda and S. cos mioides. Expand
Differential Attraction of Heliothis subflexa Males to Synthetic Pheromone Lures in Eastern US and Western Mexico
TLDR
The mate attraction signal of Heliothis subflexa (Hs) females consists of a multicomponent sex pheromone blend, and it is indicated that the addition of Z9-16:OAc alone does not increase attraction of male Hs, while Z11-16-OAc does. Expand
Identification of Minor Sex Pheromone Components of the Poplar Clearwing Moth Paranthrene tabaniformis (Lepidoptera, Sesiidae)
A chemical analysis of the crude sex pheromone gland extracts of virgin calling Paranthrene tabaniformis females, obtained from the European part of Kazakhstan, revealed the presence of fiveExpand
Molecular and functional characterization of a candidate sex pheromone receptor OR1 in Spodoptera litura
TLDR
It is inferred that variation in transcription levels of olfactory receptors may modulate sex pheromone perception in male moths and could provide some of the flexibility required to maintain the functionality of communication with females when a population is adapting to a new niche and reproductive isolation becomes an advantage.

Modification of the sex-pheromone communication system associated with organophosphorus-insecticide resistance in the obliquebanded leafroller (Lepidoptera: Tortricidae)

TLDR
An additional component, (Z)-11-tetradecenal, was identified from female tip extracts by split-less capillary gas-liquid chromatography and mass spectroscopy and was strongly stimulatory in electroantennogram studies, contributing to increased specificity of the synthetic pheromone blend to C. rosaceana.

Pheromone Blend Variation and Cross-Attraction Among Populations of the Black Cutworm Moth (Lepidoptera: Noctuidae)
TLDR
Sex pheromone quantity, blend ratio, and cross-attraction were studied in four populations of the black cutworm, Agrotis ipsilon, finding that significant differences in phersomone blend among geographically distant populations of A. ipilon did not prevent cross-Attraction under laboratory conditions.

Temporal variations in the relative amounts of pheromone in susceptible and resistant C. rosaceana may be associated with similar variation in the emission of phersomone and corresponding temporal variation inThe relative attractiveness of the two types of females. Expand

QA results suggest that qualitative differences may exist between the sex pheromone of eastern and western populations of obliquebanded leafroller and indicate the need for considering regional differences when monitoring obLiquebanding leafroller with commercial synthetic phermone blends. Expand
