    Notes: Abstract Pheromone components and sex attractant blends consisting of 3Z,6Z,9Z-triene hydrocarbons and racemic and chiral forms of3Z,6Z-cis-9, 10-epoxydienes have been elucidated for two noctuid and one geometrid moth species. MaleEuclidea cuspidea moths were attracted to blends of 3Z,6Z,9Z-heneicosatriene (3Z,6Z,9Z-21∶H) with 3Z,6Z-cis-9,10-epoxyheneicosadiene (3Z,6Z-cis-9,10-epoxy-21∶H). In addition to these compounds, 3Z,6Z,9Z-20∶H, and two regioisomeric C21 epoxides were tentatively identified in pheromone gland extracts.Caenurgina distincta moths were attracted by an 8∶∶1 blend of 3Z,6Z,9Z-20∶H with3Z,6Z-cis- 9,10-epoxy-20∶H.Eupithecia annulata moths were attracted by either 3Z,6Z-cis-9,10-epoxy-20∶H or 3Z,6Z-cis-9,10-epoxy-21∶H, and by the 95,10R enantiomer of each epoxide. 3Z,6Z,9Z-21∶H and 3Z,6Z-cis-9,10-epoxy-21∶H were tentatively identified from pheromone glands. Pheromone components were identified by a combination of coupled gas chromatography-electroantennography, gas chromatography-mass spectrometry, and field bioassays.

    Notes: Abstract Sex attractants for the geometrid mothsEufidonia convergaria andCaripeta angustiorata, and the noctuid mothRivula propinqualis have been elucidated during field screening of a series of (3Z,6Z,9Z)-triene hydrocarbons (C17–22), and the racemic and enantiomerically enriched monoepoxydienes derived from those hydrocarbons. Biologically active compounds were identified by a combination of field testing of synthetic standards, electroantennography, and coupled gas chromatography-electroantennogram detection.E. convergaria males were optimally attracted by a 1∶1 blend of (3Z,9Z)-(6S,7R)-epoxy-nonadecadiene (3Z,9Z-6S,7R-epoxy-19∶H); other abbreviations follow the same system) with (3Z,6Z,9Z)-nonadecatriene (3Z,6Z,9Z-19∶H). The 6R,7S enantiomer of the epoxide had no apparent biological activity, either as an attractant or as a behavioral antagonist. Male moths also were attracted to blends of the C18 and C20 homologs of the triene and the epoxide. 3Z,6Z,9Z-19∶H and 3Z,6Z-cis-6,7-epoxy-19∶H were identified inE. convergaria female pheromone gland extracts. Males of the geometrid moth speciesC. angustiorata were attracted by a 1∶1 blend of 3Z,6Z,9Z-19∶H and enantiomerically enriched 3Z,9Z-6R,7S-epoxy-19∶H. Males of the noctuid mothR. propinqualis were attracted by an approximately 10∶1 blend of 3Z,6Z,9Z-19∶H and enantiomerically enriched 3Z,9Z-6S, 7R-epoxy-19∶H. The components were synergistic, with neither being attractive alone. The blend ratio was quite specific, as the attractiveness of blends decreased sharply on either side of the optimum ratio.

    Effects of host plant,Gossypium hirsutum L., on sexual attraction of cabbage looper moths,Trichoplusia ni (Hübner) (Lepidoptera: Noctuidae) (1994)

    Notes: Abstract 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. Increased sexual attractiveness of females with plants may be a result of stimulation of pheromone release in response to plant odor, since more males were attracted when odor of cotton foliage was passed over females than when odor of females was passed over cotton foliage before venting into the flight tunnel. Increased sexual attractiveness of males with plants is due in part to host odor enhancement of female attraction to male pheromone, since more females were attracted to synthetic male pheromone (a blend of enantiomers of linalool and isomers of cresol) and a cotton leaf extract than were attracted to male pheromone alone. A short synthesis procedure was developed for (S)-(+)-linalool, the major component of the male sex pheromone, isolated from hair pencils, used in these tests.

    Notes: Abstract Enantiomerically enriched forms of (Z)-6-cis-9,10-epoxymonoenes and (Z)-9-cis-6,7-epoxymonoenes of chain lengths C17−20 were synthesized by Sharpless asymmetric epoxidation of allylic alcohol intermediates, followed by tosylation or halogenation and chain extension. The resulting monounsaturated epoxides were field tested as sex attractants for lepidopteran species.Euchlaena madusaria Walker males were attracted to blends of the enantiomers of (Z)-6- cis- 9,10-epoxynonadecene 6Z-cis-9,10-epoxy-19:H; IUPAC name [2α,3α(Z)]-2-pentyl-3-(2-dodecenyI)oxirane in combination with 6Z,9Z-19: H. The response was antagonized by 9Z-cis-6,7-epoxy-19: H. 6Z,9Z-19: H was tentatively identified in pheromone gland extracts.Xanthotype sospeta Drury male moths were attracted to lures containing 6Z-9S,10R-epoxy-19: H; the response was antagonized by the opposite enantiomer.Pal-this angulalis Hübner males were attracted to 9Z-6S,7R-epoxy-19:H; the opposite enantiomer was antagonistic. 6Z,9Z-19:H and 9Z-cis-6,7-epoxy-19:H and 9Z-cis-6,7-epoxy-19:H were tentatively identified in pheromone gland extracts fromAnacamptodes humaria Guenée females. In field trails, 9Z-6R,7S-epoxy-19:H proved to be the attractive enantiomer, and the response was potentiated by 6Z,9Z-19:H. Mechanisms by which unique chemical communication channels are maintained by each species are discussed.
