Novel Components of the Sex Pheromones Produced by Emerald Moths: Identification, Synthesis, and Field Evaluation
TLDR
The field evaluation of the synthetic polyenes in a mixed forest of Tokyo revealed the following new male attractants for emerald moths: Idiochlora ussuriaria by a C17 6,9,12-triene and Jodis lactearia by a 2,3,6,9-tetraene, indicating the characteristic chemical structures of Geometrinae pheromones.
Synthesis of the Deuterated Sex Pheromone Components of the Grape Borer, Xylotrechus pyrrhoderus
TLDR
Deuterated derivatives of both components were synthesized by starting from a Wittig reaction between hexanal and an ylide derived from D5-iodoethane and ending with enantiomeric resolution by chiral HPLC to confirm the biochemical conversion.
Instrumental Analysis of Terminal-Conjugated Dienes for Reexamination of the Sex Pheromone Secreted by a Nettle Moth, Parasa lepida lepida
TLDR
It was confirmed that the female moths exclusively produced the (Z)-isomer of the 7,9-diene, and a GC-EAD analysis and a field evaluation with both geometrical isomers indicated that the mating communication of P. l.
Chiral methyl-branched pheromones.
TLDR
While this review deals only with chiral methyl-branched pheromones, the chemical structures of more than one hundred non-terpene compounds have been determined by applying excellent analytical techniques and by employing trustworthy chiral sources and ingenious enantioselective reactions.
Female Sex Pheromone of Cystidia couaggaria couaggaria (Lepidoptera: Geometridae): Identification and Field Attraction
TLDR
Mixtures of the synthetic C21 and C23 trienes in a ratio of 2:3 and 1:4 successfully attracted males of this diurnal species during daytime, and the male antennae responded to the C25 triene and saturated hydrocarbons, but their synergistic effects were not observed on the male attraction in the fields.
Positions and Stereochemistry of Methyl Branches in the Novel Sex Pheromone Components Produced by a Lichen Moth, Lyclene dharma dharma
TLDR
The GC-MS analyses revealed that natural components I and II were best fitted with those of 1 and 2, respectively, among the methyl-2-octadecanones examined, indicating the usefulness of this analytical instrument and authentic standards for the determination of the positions of methyl branches.
