    Notizen: Abstract Mean catches of spruce budworm,Choristoneura fumiferana (Clemens), moths were not significantly different among four small-tree thinning treatments of young spruce-fir-hemlock regeneration. Significant inverse relationships were found between trap catches and distances to nearby spruce-fir-hemlock overstory. Prevailing wind directions indicated that moths were attracted anemotactically to upwind pheromone sources. No definite trends were detected between catches and temperature or precipitation.

    Sex pheromone components ofEuxoa drewseni Chemical identification, electrophysiological evaluation, and field attractancy tests (1983)

    Notizen: Abstract Eleven compounds structurally similar to known lepidopterous pheromone components were identified in the extract from 18 calling female moths ofEuxoa drewseni (Staudinger). The identifications were done by gas chromatography-mass spectrometry and high-resolution gas chromatography with flame ionization and electroantennographic detectors simultaneously. Detector antennae were from five species of moths. In the field, male moths were specifically attracted to a three-component blend of dodecyl, (Z)-5-dodecenyl, and (Z)-7-tetradecenyl acetates in a ratio of 2∶6∶1. This blend at 1000 μg/rubber septum dispenser is recommended as a trap bait for monitoring purposes. Low concentrations of (Z)-7-dodecenyl acetate or (Z)-7-tetradecenol inhibited the attraction of moths to the three-component blend. (Z)-7-Pentadecenyl acetate functioned as a parapheromone in place of (Z)-7-tetradecenyl acetate in the pheromone blend, and they appear to react via the same antennal receptor.

    Triunsaturated hydrocarbons, sex pheromone components ofCaenurgina erechtea (1983)

    Notizen: Abstract (Z,Z,Z)-3,6,9-Eicosatriene and (Z,Z,Z)-3,6,9-heneicosatriene have been identified as components of the sex pheromone of the noctuid,Caenurgina erechtea (Cramer), the forage looper. Structural assignments were made on the basis of spectroscopic and chromatographic data and were confirmed by comparison with synthetic material. Flight tunnel behavioral studies demonstrated that either component, when tested individually, would elicit wing fanning responses in males; however, mixtures of the two components increased this response and were essential for initiation of upwind flight and landing. In field experiments, traps baited with either component alone captured few or no adult forage looper males while those baited with both components captured several target males.

    Notizen: Abstract Sixteen pheromone-like compounds were identified in abdomen tip washes and excised abdomen tip extracts of calling females of driedfruit moth,Vitula edmandsae serratilineella Ragonot. Identifications were by high-resolution gas chromatography-mass spectrometry, and gas chromatography with flame ionization and electroantennographic detectors. Male moths were attracted to a blend of (Z)-9,(E)-12-tetradecadienol and (Z)-9,(E)-12-tetradecadienal in a ratio of 100∶1 at 500 μg/rubber septum dispenser, which is recommended for monitoring purposes. Low concentrations of (Z)-9-tetradecenol (0.5%) and (Z)-9-tetradecenal (0.1%) may be beneficial for the attraction of males, but 1–2% of (E)-9,(E)-12- or (Z)-9,(Z)-12-tetradecadienol, or (Z)-9,(E)-12-tetradecadienyl acetate inhibited their attraction. Gravid female moths were attracted to traps that captured large numbers of males. Females may be attracted to male hairpencil or forewing gland secretions emitted near the traps or that accumulate in the traps.

    Notizen: Abstract All four geometrical isomers of 5,7-dodecadien-1-ol have been stereoselectively synthesized by using Wittig condensation reactions. (5 Z,7E)-5,7-Dodecadien-1-ol and its corresponding aldehyde are components of the sex pheromone of the forest tent caterpillar. (5 E,7 Z)-5,7-Dodecadienal is a component of the pheromone of the western tent caterpillar. These compounds have been successfully tested in the field.

    Notizen: Abstract A sex pheromone extract from fall cankerworm moths,Alsophila pometaria, attracted conspecific males in field tests. Four EAG-active components were isolated from the extract and identified by GC-MS, highfield PMR spectroscopy, and microchemical techniques asn-nonadecane (I), (Z,Z,Z)-3,6,9-nonadecatriene (II), (Z,Z,Z,E)-3,6,9,11-nonadecatetraene (III), and (Z,Z,Z,Z)-3,6,9,11-nonadecatetrane (IV). Studies of the behavioral responses of male moths in a flight tunnel to the isolated components showed II, III, and IV were the major components of the sex pheromone. No sex pheromone behavioral responses were observed for I.

    Identification of sex pheromone components of redbacked cutworm,Euxoa ochrogaster, and modification of sex attractant blend for adult males (1980)

    Thema: Biologie , Chemie und Pharmazie
    Notizen: Abstract Pheromone washes from calling female moths of redbacked cutworm,Euxoa ochrogaster (Guenée), contained the following acetates that are structurally similar to those of known lepidopteran pheromones (%): decanyl (8.7), dodecanyl (8.5), (E)-5-dodecenyl (3.3), (Z)-5-dodecenyl (76.4), (Z)-7-dodecenyl (3.1), and (Z)-9-dodecenyl (trace〈0.5%). This is the first time that (Z)-5-dodecenyl acetate has been identified as a pheromone component. Three types of specific receptor cells were found in the male antennae, and they responded to (Z)-5-decenyl acetate, (Z)-5- and (Z)-7-dodecenyl acetates, respectively. Strong electroantennographic detector responses were also recorded for these three acetates and for (Z)-5-undecenyl acetate. The evidence for the presence of (Z)-5-decenyl acetate in the pheromone washes was inconclusive. The presence of (Z)-7- and the absence of (Z)-8-dodecenyl acetates were confirmed by a special electroantennographic detector technique in which the detector antennae were from males of other species that were known to have strong responses to these acetates. This is a very useful technique. Field results show that low concentrations (0.1–1.3%) of (Z)-5-decenyl acetate were synergistic when tested in a previously reported blend, but 6% was inhibitory. Similarly, (Z)-7-dodecenyl acetate at 2% or less may be essential for the attraction of males, but in previous tests at 14% it also was inhibitory. Species-specific attractant blends for redbacked cutworm males are described.

    Notizen: Abstract Evidence is presented indicating the presence of the tick sex pheromone, 2,6-dichlorophenol in lipid droplets in the foveal glands ofDermacentor variabilis (Say) andDermacentor andersoni Stiles. The pheromone appears to be dissolved in the lipid droplets. The droplets consist of neutral lipids, mostly triacylglycerides and cholesterol esters. The esterified fatty acid profiles of foveal gland triacylgylcerides are different from those of other tissues examined or reported for other ticks. The percentage of shorter chain, mostly saturated fatty acids were decreased, while the longer chain polyunsaturated fatty acids were increased. The biological advantages of lipid solution for storage, translocation, and release of the sex pheromone from the female tick are discussed.

    Chemistry and field evaluation of the sex pheromone of western spruce budworm,Choristoneura occidentalis, Freeman (1982)

    Thema: Biologie , Chemie und Pharmazie
    Notizen: Abstract Chemical analyses and field bioassays showed a mixture of 92% (E)- and 8% (Z)-11-tetradecenal to be the sex attractant pheromone of the western spruce budworm,Choristoneura occidentalis Freeman. Females were also found to emit small amounts of the corresponding acetates and alcohols, but these components were not active in the bioassay. In contrast, in whole female tip extracts, (E)-11-tetradecenyl acetate predominates, and aldehyde pheromone components are present in lesser quantities, suggesting that final biosynthesis of pheromone takes place just prior to or during emission. At release rates approximating that of the female (2–4 ng/hr), a 92∶8E∶Z blend of the synthetic aldehydes was at least as attractive as live females. Addition of the corresponding acetates or alcohols up to 50% of the aldehyde content did not significantly enhance or inhibit attraction. No major differences were apparent in pheromone production of females from a laboratory stock or from field collections from diverse geographic locations ranging from Colorado to British Columbia.
