    Studies on the isolation and bioassay of the sex pheromone of the drugstore beetle,Stegobium paniceum (Coleoptera: Anobiidae) (1975)
    Springer
    Journal of chemical ecology 1 (1975), S. 413-422

    Notes: Abstract Females ofStegobium paniceum (L.) produce a sex pheromone that causes an excitation and attraction of the males. Male response was highest 5–12 days after adult emergence. Pheromone titer of unmated females increased steadily after 1 day, reached a plateau after 5 days, and continued until at least 14 days. Mature males showed a threshold responsiveness of 3 × 10−7 μg pheromone. The pheromone titer per female ranged from 50 to 200 ng. On the basis of a high-resolution mass spectrum the empirical formula of the pure isolated pheromone molecule was determined to be C13H20O3. The pheromone was further defined by its Chromatographic behavior and spectroscopic properties.

    Chiral specificity of the sex pheromone of the red-headed pine sawfly,Neodiprion lecontei (1979)
    Springer
    Journal of chemical ecology 5 (1979), S. 237-249 
    Details
    ISSN: 1573-1561
    Keywords: Sawflies ; pheromone ; stereospecificity ; (−)-erythro configuration ; enantiomers ; chirality ; optical isomers ; Neodiprion lecontei

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract The stereospecificity of the sawfly pheromone 3,7-dimethyl-2-pentadecanol acetate againstNeodiprion lecontei was studied. Twoerythro and a 1∶1 mixture ofthreo isomers (C-2 and C-3) were synthesized for this purpose. It was found that only one isomer with (−)-erythro configuration (2S, 3S) had biological activity. The potency of this synthetic pheromone was roughly identical to the one shown by the naturally occurring pheromone in this species.

    Field responses of redheaded pine sawfly males to a synthetic pheromone and virgin females in Florida (1982)
    Springer
    Journal of chemical ecology 8 (1982), S. 471-475 
    Details
    ISSN: 1573-1561
    Keywords: Neodiprion lecontei ; Hymenoptera ; Diprionidae ; 3,7-di-methylpentadecan-2-ol acetate ; trapping ; pheromone ; time of year ; time of day

    Topics: Biology , Chemistry and Pharmacology
    Notes: Abstract Field tests using the sawfly pheromone [3,7-dimethylpentadecan-2-ol acetate with (−)-erythro configuration (2S,3S)] were conducted near Gainesville, Florida, during 1978–1981 to determine the attraction ofNeodiprion lecontei males to baited traps with respect to time of year and time of day. Greatest numbers of males were caught during May, July, and September in traps placed within a pine stand from July 1978 to July 1979. Males were only caught between 1400 and 2000 hr on 10 dates in June and 10 dates in September–October 1980, and 10 dates in June 1981, with greatest catches from 1600–1800 hr. Catches in a synthetic-baited trap and in virgin female-baited traps were similar with respect to time of day.
