Kinjo, Mieko published the artcileSex pheromone of the sugarcane shoot borer, Tetramoera schistaceana Snellen (Lepidoptera:Tortricidae:Olethreutinae). Isolation and identification, COA of Formula: C14H26O2, the publication is Nippon Oyo Dobutsu Konchu Gakkaishi (1996), 40(3), 191-197, database is CAplus.

The structure of the sex pheromone of the most important sugarcane pest, sugarcane shoot borer, T. schistaceana was determined to establish an integrated method of controlling this pest. The sex pheromone was extracted from the abdominal tips of virgin females. Using laboratory bioassay in a small flight tunnel, 2 active components of the sex pheromone were isolated. The major and minor components were identified as (Z)-9-dodecenyl acetate and (E)-9,11-dodecadienyl acetate, resp. The major component alone had no attractivity but a mixture of the 2 components showed strong activity in sugarcane fields. The sex pheromone of T. schistaceana was determined to be a 100:1 mixture of (Z)-9-dodecenyl acetate and (E)-9,11-dodecadienyl acetate. The synergist increasing the attractivity of the sex pheromone was (E)-7,9-decadienyl acetate. The best formulation for the sex attractant was a mixture of the 2 pheromone components and the synergist at a ratio of 1000:10:1.

Hirai, Yoshio published the artcileSex pheromone of fall armyworm: laboratory evaluation of male responses and inhibition of mating by pheromone components, Name: (Z)-Dodec-9-en-1-yl acetate, the publication is Journal of Chemical Ecology (1982), 8(1), 267-73, database is CAplus and MEDLINE.

Two components of the fall armyworm, Spodoptera frugiperda, sex pheromone, (Z)-9-dodecen-1-ol acetate (DDA) [16974-11-1] and (Z)-9-tetradecen-1-ol (TDA) [35153-15-2] were tested alone and in combination to determine their effects on male sexual response and inhibition of mating in the laboratory The threshold response for armyworm males was lower for TDA than for DDA, and males responded to TDA over a wider range of dosages. Although TDA is not attractive to armyworm males in the field, this compound was highly effective in reducing mating under laboratory conditions.

Dunkelblum, Ezra published the artcileChemical characterization and species specificity of sex pheromones of Plusiinae moths in Israel, Product Details of C14H26O2, the publication is Archives of Insect Biochemistry and Physiology (1993), 22(3-4), 413-24, database is CAplus.

The female sex pheromones of four sympatric Plusiinae species, Autographa gamma, Chrysodeixis chalcites, Cornutiplusia circumflexa, and Trichoplusia ni were investigated in Israel. The research concentrated on the behavioral reproductive isolation regulated by their sex pheromones. The chem. composition of the four sex pheromones was determined by anal. of pheromone gland extracts, and in addition entrained volatiles released from virgin female C. chalcites and T. ni were also analyzed. The pheromones of these latter two species were found to contain several components, among which Z7-12:Ac was the main one. The pheromone glands of A. gamma and C. circumflexa were found to contain relatively small amounts of material and only Z7-12:Ac and Z7-12:OH could be pos. identified. These two pheromone components were present in the two species in roughly inverse ratios. Whereas A. gamma utilizes Z7-12:Ac as the main or sole pheromone component, C. circumflexa requires both Z7-12:OH and Z7-12:Ac, with the alc. being predominant. This is the first reported Plusiinae species using Z7-12:OH as the main pheromone component. Behavioral studies in the wind tunnel and field tests indicate that females of each of the four Plusiinae species utilize a species-specific blend of chems., consisting of attractive and antagonistic components, to attract conspecific males. Such a complementary strategy provides improved behavioral reproductive isolation among the sympatric species. For example, Z5-12:Ac, which is a specific component of the T. ni sex pheromone, may be redundant as regards the attraction of T. ni males. However, addition of small amounts of this compound to pheromone blends of A. gamma and C. chalcites resulted in complete inhibition of the males’ flight behavior and trap catch; thus contributing significantly to the specificity of the T. ni sex pheromone. The relatively high proportion of Z7-12:OH in the sex pheromone of C. circumflexa, essential to the latter, is highly inhibitory to the three other Plusiinae species. The only case of cross-attraction occurred when T. ni males were attracted to a certain extent to A. gamma lures and females.

Smith, M. T. published the artcileHickory shuckworm Cydia caryana: electroantennogram and flight tunnel studies of potential sex pheromone components, Product Details of C14H26O2, the publication is Entomologia Experimentalis et Applicata (1987), 44(1), 23-30, database is CAplus.

Electroantennogram (EAG) measurements of male C. caryana moth antennal olfactory response to monounsaturated 12 and 14 carbon alcs. and acetates indicated that the (E)-8-, (E)-10-conjugated double bond system of a dodecadien-1-ol acetate is a critical chem. structural component of the C. caryana sex pheromone. Addnl., EAG measurements implicated (E)-8-dodecen-1-ol acetate, (Z)-8-dodecen-1-ol acetate, (Z)-9-dodecen-1-ol acetate, and (Z)-12-tetradecen-1-ol as potential minor pheromonal components. An EAG dosage-response study suggested that there were ≥2 heterologous populations of pheromone acceptors. Behavioral anal. of male moth response in a flight tunnel to compounds which evoked the stronger EAG responses suggested that (E,E)-8,10-dodecadien-1-ol acetate and (Z)-9-dodecen-1-ol acetate resemble or are C. caryana sex pheromonal components, while (Z)-8-dodecen-1-ol acetate and (E)-10-dodecen-1-ol acetate are either parapheromones or are minor pheromone components. Behavioral significance of (Z)-12-tetradecen-1-ol was difficult to interpret in the flight tunnel.

Marques, Francisco De A. published the artcileKovats retention indexes of monounsaturated C₁₂, C₁₄, and C₁₆ alcohols, acetates and aldehydes commonly found in lepidopteran pheromone blends, Related Products of esters-buliding-blocks, the publication is Journal of the Brazilian Chemical Society (2000), 11(6), 592-599, database is CAplus.

Many lepidopteran pheromones consist of blends of monounsaturated alcs., aldehydes and acetates. These compounds frequently are obtained in only nanogram quantities from pheromone gland extracts, prohibiting use of most standard spectroscopic methods. However, use of GC retention indexes, particularly in combination with mass spectrometry and electroantennograms, can provide substantial information about trace amounts of unknowns. Comparison of Kovats indexes (KIs) of an unknown with those of standards can provide an unambiguous identification, or at least, limit the number of possible structures to a few compounds Furthermore, because KIs are highly reproducible, a full set of standards is not necessary; comparisons can be made using tables of KIs determined in another laboratory We provide here tables of the KIs of almost all possible isomers of monounsaturated alcs., aldehydes, and acetates with 12, 14, or 16 carbon chain lengths, measured on nonpolar (DB-5) and polar (DB-WAX) stationary phases.

Pheromone traps were more efficient than blacklight traps for detecting and monitoring adult populations of fall armyworm (S. frugiperda) in southwestern Ontario. Several dispenser-chem. combinations were strongly attractive but best results were obtained with sticky traps baited with rubber septa impregnated with combinations of (Z)-9-dodecenyl acetate  [16974-11-1] and (Z)-9-tetradecenyl acetate  [16725-53-4].

Fiandanese, Vito published the artcileA general approach to the synthesis of monoolefinic insect sex pheromones of Z- or E-configuration, Application In Synthesis of 16974-11-1, the publication is Journal of the Chemical Society, Perkin Transactions 1: Organic and Bio-Organic Chemistry (1972-1999) (1985), 1115-19, database is CAplus.

Several insect sex pheromones and structurally related alkenes were prepared by 2 sequential cross-coupling reactions starting from (Z)- or (E)-BrCH:CHSPh [(Z)- or (E)-I]. Z-Isomers were prepared by sequential cross-coupling of (Z)-I with 2 Grignard reagents in the presence of [PdCl₂(PPh₃)₂] (II) and [NiCl₂(dppe)] [III; dppe = (Ph₂PCH₂)₂], resp., whereas E-isomers were prepared by sequential cross-coupling of (E)-I with Grignard reagents in the presence of III. E.g., sequential treatment of (Z)-I with Me(CH₂)₁₂MgBr in the presence of II and Me(CH₂)₇MgBr in the presence of III in Et₂O at room temperature gave 75% (Z)-Me(CH₂)₁₂CH:CH(CH₂)₇Me, the sex pheromone of the housefly.

Groot, Astrid T. published the artcileHost strain specific sex pheromone variation in Spodoptera frugiperda, Product Details of C14H26O2, the publication is Frontiers in Zoology (2008), No pp. given, database is CAplus and MEDLINE.

The fall armyworm Spodoptera frugiperda consists of 2 distinct strains with different host plant preferences for corn and rice. To assess whether pheromonal-mediated behavioral isolation accompanies the habitat isolation on different host plants, we compared the sex pheromone composition among females of the 2 strains. Pheromone glands were extracted with or without injection of pheromone biosynthesis activating neuropeptide (PBAN). To assess the mode of inheritance of this variation, we also analyzed the pheromone composition of F₁ hybrid females. Relative to intra-strain variation, the pheromone composition of the 2 strains differed significantly. Corn strain females contained significantly more of the 2nd most abundant pheromone compound Z11-16:Ac (m), and significantly less of most other compounds, than rice strain females. When females were injected with PBAN before their glands were extracted, the differences between the strains were less pronounced but still significant. The pheromone composition of hybrid females showed a maternal inheritance of the major component Z9-14:Ac (M) as well as of Z11-16:Ac (m). Most other compounds showed an inheritance indicating genetic dominance of the corn strain. The within-strain phenotypic correlations among the various components were consistent with their hypothesized biosynthetic pathway, and between-strain differences in the correlation structure suggested candidate genes that may explain the pheromone differences between the 2 strains. These include Δ9- and Δ11 desaturases, and possibly also a Δ7-desaturase, although the latter has not been identified in insects so far. The 2 host strains of S. frugiperda produce systematically differing female sex pheromone blends. Previously-documented geog. variation in the sexual communication of this species did not take strain identity into account, and thus may be partly explained by different strain occurrence in different regions. The finding of pheromone differences reinforces the possibility of incipient reproductive isolation among these strains, previously shown to differ in the timing of nocturnal mating activity and host plant use. Finding the genetic basis of the pheromone differences, as well as these other biol. traits, will help to elucidate the role of premating isolation in the continuing differentiation of these two strains that may eventually lead to speciation.

Herbert, Myles B. published the artcileConcise syntheses of insect pheromones using Z-selective cross metathesis, Product Details of C14H26O2, the publication is Angewandte Chemie, International Edition (2013), 52(1), 310-314, database is CAplus and MEDLINE.

The facile synthesis of lepidopteran female sex pheromones was achieved using ruthenium-based Z-selective olefin metathesis. The synthesis of these compounds provides insight into the reactivity and selectivity of the catalyst, which is markedly distinct from previous generations of metathesis catalysts. The development of new Z-selective catalysts and operating on a larger scale should make this methodol. even more selective and efficient. Compounds containing a variety of functional groups, including alcs., acetates, aldehydes, ketones, and epoxides, were easily prepared in a minimal number of steps from com. sources, including several seed-oil derivatives It was demonstrated that ruthenium-based Z-selective metathesis provides an attractive route to form complex internal olefins in good yields with high cis-selectivity, and could emerge as a viable alternative to other popular methods used to form cis olefins, such as the partial hydrogenation of alkynes and the Wittig reaction.
