Arn, Heinrich published the artcileSex pheromone of Eupoecilia ambiguella female: analysis and male response to ternary blend, Recommanded Product: (Z)-Dodec-9-en-1-yl acetate, the publication is Journal of Chemical Ecology (1986), 12(6), 1417-29, database is CAplus and MEDLINE.

Sex gland extracts and washes of E. ambiguella contained 10-20 ng/female of the primary sex pheromone component Z-9-dodecenyl acetate (Z9-12:Ac), accompanied by a number of related compounds These are (E9-12:Ac), Z-9-dodecen-1-ol (Z9-12:OH), saturated acetates of 12, 16, 18, and 20 Cs, and traces of a doubly unsaturated acetate, tentatively identified as a 9,11-dodecadienyl acetate. Octadecyl acetate (18:Ac) predominated among the pheromone-related components, making up 1-2, occasionally 20-30-fold the amount of Z9-12:Ac. The same compounds were also found in field-collected females and in effluvia. Z-9-Undecenyl acetate, which is a male attractant on its own, was also found in a sample of female effluvia. A hierarchy in the ethol. function of the pheromone components was observed Z9-12:Ac was an attractant for E. ambiguella males. Dodecyl acetate (12:Ac) was not attractant on its own, but augmented male catch when added to the main attractant. Addition of 18:Ac augmented attraction only when both Z9-12:Ac and 12:Ac were present. Wind-tunnel tests demonstrated that 18:Ac also raised the disorientation threshold, as previously shown for 12:Ac. Other compounds, with the possible exception of addnl. saturated acetates, had either no effect on trap catch or, in the case of E9-12:Ac, Z9-12:OH, and E-9,11-dodecadienyl acetate, were inhibitory above a certain level. A blend of roughly equal parts of Z9-12:Ac, 12:Ac, and 18:Ac provided the best blend for E. ambiguella known to date.

The rate of release of dodecyl alc., cis-9-dodecenyl acetate, trans,trans-8,10-dodecadienol, and cis,trans-dodecadienyl acetate from a rubber tube was 233.63, 212.75, 21.29, and 22.90 μg/day, resp. Thus, the functional group and the number of double bonds of the attractant determined the rate of release from rubber. The rate of cis-9-dodecenyl acetate and trans,trans-8,10-dodecadienol release from Al foil was 336.51 and 1521.51 μg/day, resp., from a dense, small-pore filter 556.26 and 2149 μg/day, resp., and from polysulfone membrane PSU-40-s 10.20 and 784.55 μg/day, resp. This emphasizes the effects of the carrier.

Roh, Gwang Hyun published the artcileElectrophysiological and behavioral activities of sex pheromone and structurally related compounds in lightbrown apple moth, Epiphyas postvittana, Synthetic Route of 16974-11-1, the publication is Chemoecology (2022), 32(1), 1-13, database is CAplus.

Species-specific pheromone communication in moths is often achieved by the precise control of the production of a multi-component sex pheromone blend in females and selective perception of pheromone compounds in males. Reproductive isolation mediated by sex pheromone can be enhanced by the sensitive detection of structurally related non-pheromone components that are not used as pheromone in the same species but used as pheromone components in similar species. Here, we identified several unsaturated aliphatic acetates inhibiting the attraction of male moths to conspecific female sex pheromone in the lightbrown apple moth, Epiphyas postvittana (Walker) (Lepidoptera: Tortricidae), through electroantennogram (EAG) and field trapping studies. In EAG screening with 46 pheromone and structurally related compounds, eleven compounds exhibited significant male-specific EAG responses at 1 μg dose. The EAG-active compounds were mainly mono- or di-unsaturated 14-carbon acetates. In subsequent field trapping tests to evaluate the behavioral activities of the EAG-active compounds on male attraction to the binary blend (E11-14:Ac + E9E11-14:Ac) of female sex pheromone of E. postvittana, each of nine compounds (E9-12:Ac, Z9-12:Ac, E9-14:Ac, Z9-14:Ac, Z10-14:Ac, Z11-14:Ac, Z12-14:Ac, Z9E11-14:Ac and Z9E12-14:Ac) displayed clear inhibition of male moths to the sex pheromone blend in a dose-dependent manner. Our findings provide useful information in understanding the pheromone communication system of E. postvittana and related species.

Tamaki, Yoshio published the artcileDecreased rates of pheromonal components in attractant formulations for tea tortricid moths under field conditions, Safety of (Z)-Dodec-9-en-1-yl acetate, the publication is Nippon Oyo Dobutsu Konchu Gakkaishi (1983), 27(2), 154-6, database is CAplus.

Attractant formulations for tea tortricid moths, in rubber septums or plastic capsules, containing a 7:3:1:20 mixture of (Z)-9-tetradecenyl acetate (I) [16725-53-4], (Z)-11-tetradecenyl acetate (II) [20711-10-8], (E)-11-tetradecenyl acetate (III) [33189-72-9], and 10-methyldodecyl acetate (IV) [70711-42-1], or a 60:3:1 mixture of II, (Z)-9-dodecenyl acetate (V) [16974-11-1], and 11-dodecenyl acetate (VI) [35153-10-7] were held in the field under direct sunlight, and dissipation of these components was studied. Each component dissipated faster from plastic capsules than from rubber septums. Lower initial contents gave shorter half lives. Components with lower mol. weights dissipated faster. Ratios of residual amounts of I, II, III, and IV in rubber and plastic preparations kept for 100 and 60 days, resp., were within the optimum range for attracting the smaller tea tortrix moth, and those of II, V, and VI in rubber and plastic preparations held for 60 and 30 days, resp., were also within the optimum range for attracting the tea tortrix moth. Decreases in the effectiveness of attractant formulations for tea tortricid moths in the field were ascribed to decreases in volatilization rates and not to alterations of optimum component ratios.

Tamaki, Yoshio published the artcileSelection of disruptants of pheromonal communication in both the smaller tea tortrix moth and the tea tortrix moth (Lepodeptera:Tortricidae), Computed Properties of 16974-11-1, the publication is Nippon Oyo Dobutsu Konchu Gakkaishi (1983), 27(2), 124-30, database is CAplus.

Six pheromonal components of the smaller tea tortrix moth and the tea tortrix moth and their 5 related compounds were evaluated for their activities as communication disruptants. When placed outside of synthetic pheromone traps, (Z)-11-tetradecenyl acetate (I) [20711-10-8], (Z)-9-tetradecenyl acetate (II) [16725-53-4], and (Z)-9-dodecenyl acetate (III) [16974-11-1] inhibited the attractancy of both pheromone mixtures for male moths. Mating of tethered females of the smaller tea tortrix moth was suppressed by I, whereas that of the tea tortrix moth was suppressed by I, III, and synthetic pheromone mixtures of both species. I and a 1:1:1 mixture of I, II, and III were the most effective communication disruptants toward both species.

Akers, R. Patrick published the artcileResponse specificity of male olfactory receptor neurons for the major and minor components of a female pheromone blend, Synthetic Route of 16974-11-1, the publication is Physiological Entomology (1991), 16(1), 1-17, database is CAplus.

The sex attractant of the female redbanded leafroller moth, Argyrotaenia velutinana, is a blend of 7 compounds Specialized olfactory receptor neurons had been found for only 2 of the compounds, (Z)-11-tetradecenyl acetate (Z11-14:Ac) and (E)-11-tetradecenyl acetate (E11-14:Ac). These receptor neurons were always found in pairs within the long trichoid sensilla, which are the most abundant multi-pored sensilla on the male antenna. A systematic survey of all regions of the male antenna with standard extracellular recording techniques was undertaken to find receptor neurons responsive to the remaining 5 minor components of the female pheromone. Of the 113 long trichoid sensilla sampled, all contained 2 receptor neurons, one specialized for Z11-14:Ac and a second specialized for E11-14:Ac. A comparable number of recordings were then obtained from the less abundant classes of multi-pored sensilla. Two new receptor neuron types were found, responsive to the minor pheromone components (E)-9-dodecenyl acetate (E9-12:Ac) and (Z)-9-dodecenyl acetate (Z9-12:Ac). Scanning electron micrographs indicated that these recordings were obtained from shorter, narrower trichoid sensilla. The majority of these sensilla appeared to contain 3 neurons capable of spontaneous action potential production In each sensillum, only one receptor neuron appeared to respond to stimulation with a minor component of the female blend. The remaining 2 neurons did not respond to the chem. stimuli evaluated.
