    Identification of the sex pheromone of the German cockroach, Blattella germanica (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-02-19
    Description: The sex pheromone of the German cockroach, Blattella germanica, has been characterized as gentisyl quinone isovalerate. This cockroach is a major cause of allergic disease and serves as a mechanical vector of pathogens, making it one of the most important residential and food-associated pests worldwide. The sex pheromone-producing gland in adult females was identified in 1993, but thermal instability of the pheromone made characterization difficult. Now, using a new preparative gas chromatography approach coupled with electroantennographic detection, we have isolated and characterized the pheromone, which we term blattellaquinone, and confirmed the identification by chemical synthesis. The synthetic pheromone was active in behavioral assays and highly effective in field trapping tests, which suggest that it may provide a new tool in cockroach population detection, monitoring, and control.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Nojima, Satoshi -- Schal, Coby -- Webster, Francis X -- Santangelo, Richard G -- Roelofs, Wendell L -- New York, N.Y. -- Science. 2005 Feb 18;307(5712):1104-6.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Entomology, New York Agricultural Experiment Station, Cornell University, Geneva, NY 14456, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/15718472" target="_blank"〉PubMed〈/a〉

    Sex Pheromone Biosynthesis in Trichoplusia ni: Key Steps Involve Delta-11 Desaturation and Chain-Shortening (1983)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1983-06-24
    Description: In addition to the primary pheromone component (Z)-7-dodecenyl acetate, the sex pheromone gland of Trichoplusia ni contains the immediate fatty acyl precursor (Z)-7-dodecenoate and a large quantity of (Z)-11-hexadecenoate. Labeling experiments showed that (Z)-11-hexadecenoate is chain-shortened to (Z)-9-tetradecenoate, and that this in turn is chain-shortened to (Z)-7-dodecenoate. The same mechanism appears to explain the sex pheromone compositions of many other moth species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Bjostad, L B -- Roelofs, W L -- New York, N.Y. -- Science. 1983 Jun 24;220(4604):1387-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17730655" target="_blank"〉PubMed〈/a〉

    Sex pheromone of the winter moth, a geometrid with unusually low temperature precopulatory responses (1982)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1982-08-13
    Description: The sex pheromone for the winter moth, Operophtera brumata (L.), has been identified as the novel compound (Z,Z,Z)-1,3,6,9-nonadecatetraene. The male moths respond to the pheromone at low temperatures (4 degrees to 15 degrees C) and exhibit an upper response limit that coincides with the lower response limit for other reported moth sex pheromone systems. The pheromone attracted two other geometrid species, O. bruceata (Bruce spanworm) and O. occidentalis.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roelofs, W L -- Hill, A S -- Linn, C E -- Meinwald, J -- Jain, S C -- Herbert, H J -- Smith, R F -- New York, N.Y. -- Science. 1982 Aug 13;217(4560):657-9.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17817538" target="_blank"〉PubMed〈/a〉

    Close-range attraction of female oriental fruit moths to herbal scent of male hairpencils (1981)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1981-12-18
    Description: A blend of ethyl trans-cinnamate, methyl 2-epijasmonate, methyl jasmonate, and (R)-(-)-mellein, identified from the hairpencils of male Oriental fruit moths, attracts sex pheromone-releasing females several centimeters away. The chemicals thereby duplicate the behavioral effect elicited by hairpencil-displaying males during courtship; the chemicals also produce the herbal scent emanating from the hairpencils.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Baker, T C -- Nishida, R -- Roelofs, W L -- New York, N.Y. -- Science. 1981 Dec 18;214(4527):1359-61.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17812262" target="_blank"〉PubMed〈/a〉

    European corn borer: pheromone polymorphism or sibling species? (1978)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1978-02-03
    Description: Electrophoretic analyses of the (Z) and (E) pheromone-attracted males of Ostrinia nubilalis (Hubner), the European corn borer, in an area of coexistence indicate that these strains are not freely interbreeding. Although the populations are morphologically indistinguishable, studies of allozyme, pheromone, and hybridization suggest that the (Z) and (E) entities are genetically differentiated, perhaps to the status of semi- or sibling species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Carde, R T -- Roelofs, W L -- Harrison, R G -- Vawter, A T -- Brussard, P F -- Mutuura, A -- Munroe, E -- New York, N.Y. -- Science. 1978 Feb 3;199(4328):555-6.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17750022" target="_blank"〉PubMed〈/a〉

    Pheromone components and active spaces: what do moths smell and where do they smell it? (1987)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1987-08-07
    Description: The pheromone-mediated flight behavior of male Oriental fruit moths was observed in the field to test the hypothesis that male activation far downwind of a female is initiated by the major, or most abundant, component of the pheromone blend. Males responded at significantly greater distances to the three-component pheromone blend produced by females than to the major component alone or to either binary mixture containing the major component and one minor component. These results support the alternative hypothesis that the active space of a multicomponent pheromone is a function of male perception of the female-released blend of components, rather than of the major component alone, and that so-called minor components have a greater impact on male behavior farther downwind of a female than previously thought.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Linn, C E Jr -- Campbell, M G -- Roelofs, W L -- New York, N.Y. -- Science. 1987 Aug 7;237(4815):650-2.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/17758565" target="_blank"〉PubMed〈/a〉

    Circadian changes in melatonin in the nervous system and hemolymph of the cabbage looper moth, Trichoplusia ni (1995)

    Notes: Abstract Quantitative levels of melatonin and 5-hydroxytryptamine were measured over the scotophase in the protocerebrum, subesophageal ganglion, optic lobes, thoracic ganglia, and hemolymph of adult male cabbage looper moths, Trichoplusia ni, using HPLC with electrochemical detection. Melatonin levels were very low (s 〈 1 pmol) or undetectable during the photophase, but increased in all tissues during the dark. Lowest mean levels in the dark were observed in the optic lobes (0.3 to 0.7 pmols). Maximal mean levels in the protocerebrum (5.2 pmols) occurred in the early part of the scotophase, but in all other tissues (2.8 in the subesophageal ganglion; 9.5 in thoracic ganglia) and hemolymph (18 pg/μl) maximal mean levels were observed later in the dark. Levels of 5-hydroxytryptamine in each tissue, in contrast, were higher than melatonin levels in the photophase, and in the protocerebrum and thoracic ganglia decreased during the dark, but in the optic lobes and subesophageal ganglion remained unchanged. Further, decreases in 5-hydroxytryptamine during the dark were significantly lower than the increased levels of melatonin, suggesting that active synthesis of 5-hydroxytryptamine was occurring. In a second experiment, when measured from individuals in three different photoperiods (6∶18, 12∶12, 18∶6 light∶dark) maximum mean melatonin levels in the brain (protocerebral and subesophageal ganglia) peaked within the first 1.5 h of the dark and remained at measurable levels for the duration of the dark. In a third experiment, levels of melatonin in the brain and thoracic ganglia displayed rhythmicity in continuous dark conditions but not in continuous light, when compared with profiles obtained in a normal light ∶ dark regime.
