    Isolation, identification, and synthesis of the sex pheromone of the tobacco budworm (1975)
    Springer
    Journal of chemical ecology 1 (1975), S. 203-214 
    Details
    ISSN: 1573-1561
    Keywords: sex pheromone ; Heliothis virescens (F.) ; (Z)-11-hexadecenal ; (Z)-9-tetradecenal

    Notes: Abstract The sex attractant of adult tobacco budworms,Heliothis virescens (F.) was isolated from ether washes of “calling” females and verified as active by field cage bioassays. The components of the pheromone were identified as (Z)-11-hexadecenal and (Z)-9-tetradecenal by spectroscopic and microdegradative methods. The two components are inactive when tested separately, but when they are mixed in the ratio in which they occur in female washes (16∶1, respectively), the synthesized mixture is equivalent to the natural one in attracting males in large cages. In field tests, 53 μg of synthesized mixture was competitive with four live females.

    Synthesis of the sex pheromone of the Japanese beetle (1980)
    Springer
    Journal of chemical ecology 6 (1980), S. 473-485 
    Details
    ISSN: 1573-1561
    Keywords: Synthesis ; sex pheromone ; Japanese beetle ; Popillia japonica ; (Z)- and (E)-5-(1-decenyl)dihydro-2(3H)-furanone isomers ; enantiomers of (Z)-5-(1-decenyl)dihydro-2(3H)-furanone

    Notes: Abstract The stereospecific synthesis of the sex pheromone produced by the female Japanese beetle (Popillia japonica Newman), (R,Z)-5-1-decenyl)-dihydro-2(3H)-furanone, is described. The pure syntheticR,Z form is a powerful attractant for males of the species in field bioassays and was competitive in attractiveness with live females, whereas the racemicZ isomer and theS,Z enantiomer were strong inhibitors of male response. The saturated analogs of both enantiomers were also synthesized stereospecifically.
