Dix, M. E. published the artcileSex pheromone of Retinia metallica (Busck) (Lepidoptera: Tortricidae): identification and field studies, COA of Formula: C14H26O2, the publication is Canadian Entomologist (1988), 120(8-9), 721-6, database is CAplus.

The major sex pheromone component from female moths of R. metallica was identified as Z7,E9-dodecadienyl acetate (Z7,E9:Ac) by a combination of electroantennog. (EAG), gas chromatog. (GC), and mass spectrometric analyses. In field tests, males of R. metallica were strongly attracted to Z7,E9-12:Ac. Addition of Z7,Z9-12:Ac, Z7,E9-dodecadienol (Z7,E9-12:OH), and Z7-dodecenyl acetate (Z7-12:Ac) to Z7,E9-12:Ac did not significantly alter trap catch. However, the addition of E9-dodecenyl acetate (E9-12:Ac) and Z9-12:Ac reduced trap catch. Trap catch was affected by height of placement; traps placed in the upper third of the tree (6 m) caught significantly more males than traps placed at lower heights.

Palaniswamy, P. published the artcileMechanisms of orientation disruption by sex pheromone components in the redbacked cutworm, Euxoa ochrogaster (Guenee) (Lepidoptera: Noctuidae), Application of (Z)-Dodec-9-en-1-yl acetate, the publication is Environmental Entomology (1988), 17(3), 432-41, database is CAplus.

Disruption of orientation of E. ochrogaster males to synthetic bait was studied in a flight tunnel and in small field plots in cereals, using synthetic pheromone components as disruptants. Field tests showed that increasing the dose from 0 to 100 μg per dispenser of the blend of all 4 components (Z)-5-dodecenyl acetate (Z5-12:Ac) + (Z)-7-dodecenyl acetate (Z7-12:Ac) + (Z)-9-dodecenyl acetate (Z9-12:Ac) + (Z)-5-decenyl acetate (Z5-10:Ac) or that of Z5-12:Ac and Z7-12:Ac, individually, resulted in a sharp increase in disruption up to a maximum of 75%; a further increase in the dose to 1000 μg per dispenser resulted in only a small and gradual increase in disruption, reaching a maximum of 88%. Z5-10:Ac caused approx. 78% disruption at levels of 100 μg and 1,000 μg per dispenser, and Z9-12:Ac was least effective at these doses. Flight tunnel and field observations showed that with blends, the mechanisms of disruption varied in relation to the concentrations used. The primary cause of disruption was competitive attraction at low dose levels and reduction in searching effort at high dose levels. With single components, irresp. of concentrations used, the cause of disruption was primarily reduction in searching effort. Based on these studies and those on Euxoa messoria and Malacosoma disstria, it is suggested that in moths, depending upon the species, functional nature of the pheromone components, concentrations used, and the method of disruptant dispenser placements, individual or blends of components can cause orientation disruption by competitive attraction and by modulating the behavior of males, particularly by reducing the searching effort.

Palaniswamy, P. published the artcileResponses of male redbacked cutworm, Euxoa ochrogaster (Lepidoptera:Noctuidae), to sex pheromone components in a flight tunnel, Formula: C14H26O2, the publication is Environmental Entomology (1983), 12(3), 748-52, database is CAplus.

Of 4 components of the title pheromone, individually only Z5-12:Ac ((Z)-5-dodecenyl acetate; I) [16676-96-3] and Z7-12:Ac ((Z)-5-dodecenyl acetate; II) [14959-86-5] stimulated activation responses of the E. ochrogaster males, but neither initiated upwind flight in the flight tunnel. Of all possible binary combinations only I + II elicited responses from activation to landing. Z5-10:Ac ((Z)-5-decenyl acetate) [67446-07-5] increased activation, upwind flight responses, and prolonged flight, but only when it was added to blends containing I + II. Addition of Z9-12:Ac((Z)-9-dodecyl acetate) [16974-11-1] as a 4th component increased initiation of landing response on the source. In moth pheromone systems utilizing several components, the sequence of male responses in locating and mating with a female depends upon specific combination of pheromone components and concentrations

Jahan, Israt published the artcileGC-MS phytochemical profiling, pharmacological properties, and in silico studies of Chukrasia velutina leaves: a novel source for bioactive agents, Category: esters-buliding-blocks, the publication is Molecules (2020), 25(15), 3536, database is CAplus and MEDLINE.

Chukrasia velutina is a local medicinal plant commonly known as chikrassy in Bangladesh, India, China, and other South Asian countries. The leaves, bark, and seeds are vastly used as herbal medicine for fever and diarrhea, and its leaves essential oils are used for antimicrobial purposes. In this study, we discuss the neuropsychiatric properties of C. velutina leaves through several animal models, quant. and qual. phytochem. anal., and computational approaches. Neuropsychiatric effects were performed in rodents on the methanolic extract of C. velutina leaves (MECVL). Antidepressant, anxiolytic, and sedative effects experimented through these rodent models were used such as the force swimming test (FST), tail suspension test (TST), hole board test (HBT), elevated plus maze test (EPMT), light/dark box test (LDBT), open field test (OFT), and hole cross test (HCT). In these rodent models, 200 and 400 mg/kg doses were used which exhibited a significant result in the force swimming and tail suspension test (p < 0.001) for the antidepressant effect. In the anxiolytic study, the results were significant in the hole board, elevated plus maze, and light/dark box test (p < 0.001) for doses of 200 and 400 mg/kg. The result was also significant in the open field and hole cross test (p < 0.001) for sedative action in the sake of similar doses. Moreover, qual. and quant. studies were also performed through phytochem. screening and GC-MS anal., and fifty-seven phytochem. compounds were found. These compounds were analyzed for pharmacokinetics properties using the SwissADME tool and from them, thirty-five compounds were considered for the mol. docking anal. These phytoconstituents were docking against the human serotonin receptor, potassium channel receptor, and crystal structure of human beta-receptor, where eight of the compounds showed a good binding affinity towards the resp. receptors considered to the reference standard drugs. After all of these analyses, it can be said that the secondary metabolite of C. velutina leaves (MECVL) could be a good source for inhibiting the neuropsychiatric disorders which were found on animal models as well as in computational studies.

Witzgall, Peter published the artcileNew pheromone components of the grapevine moth Lobesia botrana, Name: (Z)-Dodec-9-en-1-yl acetate, the publication is Journal of Chemical Ecology (2005), 31(12), 2923-2932, database is CAplus and MEDLINE.

Anal. of extracts of sex pheromone glands of grapevine moth females Lobesia botrana showed three previously unidentified compounds, (E)-7-dodecenyl acetate and the (E,E)- and (Z,E)-isomers of 7,9,11-dodecatrienyl acetate. This is the first account of a triply unsaturated pheromone component in a tortricid moth. The monoenic acetate (E)-7-dodecenyl acetate and the trienic acetate (7Z,9E,11)-dodecatrienyl acetate significantly enhanced responses of males to the main pheromone compound, (7E,9Z)-7,9-dodecadienyl acetate, in the wind tunnel. The identification of sex pheromone synergists in L. botrana may be of practical importance for the development of integrated pest management systems.

Vang, Le published the artcileSex Pheromones of Three Citrus Leafrollers, Archips atrolucens, Adoxophyes privatana, and Homona sp., Inhabiting the Mekong Delta of Vietnam, HPLC of Formula: 16974-11-1, the publication is Journal of Chemical Ecology (2013), 39(6), 783-789, database is CAplus and MEDLINE.

Archips atrolucens, Adoxophyes privatana, and Homona sp. are serious defoliators of citrus trees in the Mekong Delta of Vietnam. To establish a sustainable pest-management program for the 3 species, their female-produced sex pheromones were investigated by GC-EAD and GC-MS analyses, and the following multi-component pheromones were identified: (Z)-11-tetradecenyl acetate (Z11-14:OAc), (E)-11-tetradecenyl acetate (E11-14:OAc), and tetradecyl acetate (14:OAc) in a ratio of 64:32:4 for A. atrolucens; Z11-14:OAc and (Z)-9-tetradecenyl acetate (Z9-14:OAc) in a ratio of 92:8 for A. privatana; and Z11-14:OAc and (Z)-9-dodecenyl acetate (Z9-12:OAc) in a ratio of 96:4 for Homona sp. Each lure baited with synthetic components as a mimic of the natural pheromone attracted males of the target species specifically, indicating that each monounsaturated minor component plays a significant role for mating communication and reproductive isolation of the three species inhabiting the same citrus orchards. In an extract of the pheromone glands of A. atrolucens females, the content of 14:OAc was very low, but a synergistic effect was observed clearly when the saturated compound was mixed at the same level as the E11-14:OAc. The synthetic lures will provide useful tools for monitoring flights of adults of the 3 species.

Attygalle, Athula B. published the artcileGas-Phase Infrared Spectroscopy for Determination of Double Bond Configuration of Monounsaturated Compounds, Formula: C14H26O2, the publication is Analytical Chemistry (1994), 66(10), 1696-703, database is CAplus and MEDLINE.

Gas-phase Fourier-transform IR spectra allow unambiguous determination of the configuration of the double bonds of long-chain unsaturated compounds bearing RCH:CHR’ type bonds. Although the IR absorption at 970-967 cm^-1 has been used previously for the identification of trans bonds, the absorption at 3028-3011 cm^-1 is conventionally considered to be incapable of distinguishing cis and trans isomers. In this paper, the authors present a large number of gas-phase spectra of monounsaturated long-chain acetates which demonstrate that an absorption, highly characteristic for the cis configuration, occurs at 3013-3011 cm^-1, while trans compounds fail to show any bands in this region. However, if a double bond is present at the C-2 or C-3 carbon atoms, this cis :CH stretch absorption shows a hypsochromic shift to 3029-3028 and 3018-3017 cm^-1, resp. Similarly, if a cis double bond is present at the penultimate carbon atom, this band appears at 3022-3021 cm^-1. All the spectra of trans alkenyl acetates showed the expected C-H wag absorption at 968-964 cm^-1. In addition, the spectra of (E)-2-alkenyl acetates show a unique three-peak “fingerprint” pattern which allows the identification of the position and configuration of this bond. Furthermore, by synthesizing and obtaining spectra of appropriate deuteriated compounds, the authors have proved that the 3013-3011 cm^-1 band is representative of the C-H stretching vibration of cis compounds of RCH:CHR’ type.

Mitchell, Everett R. published the artcileRubber septa as dispensers for the fall armyworm sex attractant, HPLC of Formula: 16974-11-1, the publication is Journal of Environmental Science and Health, Part A: Environmental Science and Engineering (1983), A18(3), 463-70, database is CAplus.

Rubber septa were effective dispensers for the fall armyworm (Spodoptera frugiperda) sex attractant (Z)-9-dodecen-1-ol acetate (Z9-12:AC) [16974-11-1]. Trap captures were related to dose with the highest numbers of males being captured in sticky traps baited with 5 and 10 mg Z9-12:AC/septum; the 10-mg dosage gave catches of males comparable to traps baited with virgin females for up to 2 wk. The addition of 2% (Z)-9-tetradecen-1-ol acetate  [16725-53-4] to septa treated with Z9-12:AC had no significant effect on catches at any of the dosage levels. (Z)-11-hexadecen-1-ol acetate  [34010-21-4] Was also tested as a potential sex attractant.

A number of sex-pheromone components and related compounds were extracted from Adoxophyes sp. (smaller tea tortrix, STT) and A. orana fasciata (summer fruit tortrix, SFT) and identified. In the present study, sex pheromones from virgin females were collected by the filter paper adsorption method and the glass-wall adsorption method to investigate the pheromones. The efficiency of collection by the filter paper method was �0-times greater than that by the glass wall method. However, there was no difference in the ratio of pheromonal components between 2 collection methods. The amount of pheromones and their related compounds released from STT was �-times greater than that from SFT, but almost the same quantity of alcs. were discharged by each species. Sixteen acetates and 10 alcs. were detected in the female STT pheromone mixture and 11 acetates and 7 alcs. in the female SFT pheromone mixture
