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.
A Novel Lepidopteran Sex Pheromone Produced by Females of a Lithosiinae Species, Lyclene dharma dharma, in the Family of Arctiidae
TLDR
Female moths of Lyclene dharma dharma produced three pheromone components (I–III), which strongly stimulated male antennae, indicating that these methyl-branched ketones constitute a new chemical group of lepidopteran female sex phersomones.
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.
Sex Pheromones of Five Olethreutine Species (Lepidoptera: Tortricidae) Associated with the Seedlings and Fruits of Mangrove Plants in the Ryukyu Islands, Japan: Identification and Field Evaluation
TLDR
Synthetic lures baited with the main pheromone component of each species successfully attracted the target males, confirming that the sex phersomone is one of the most important factors for their reproductive isolation.
Synthesis and Chemical Characterization of Hydrocarbons with a 6,9,11-, 3,6,9,11-, or 1,3,6,9-Polyene System, Pheromone Candidates in Lepidoptera
TLDR
This work synthesized polyunsaturated hydrocarbons with a C17–C21 chain, which included an extra double bond to investigate further structural modifications on this theme of Lepidopteran Type II sex pheromones.
Propionates and Acetates of Chiral Secondary Alcohols: Novel Sex Pheromone Components Produced by a Lichen Moth Barsine expressa (Arctiidae: Lithosiinae)
TLDR
Females of a lichen moth, Barsine expressa, which inhabit Iriomote Island in Japan, were captured by a black-light trap and the pheromone gland extract was analyzed, showing a straight-chain structure of the C17 alcohols with the acyl groups located at the 7- or 8-position.
Synthesis and Field Evaluation of Methyl-branched Ketones, Sex Pheromone Components Produced by Lithosiinae Female Moths in the Family of Arctiidae
TLDR
Female moths of Lyclene dharma dharma produce a novel sex pheromone composed of three methyl-branched ketones, and effective male attraction was observed for the 2:1:1 mixture of I–III, indicating that the females do not produce only one stereoisomer for each component or that the response of the males is not disturbed by the other stereoisomers of natural isomers produced by the females.
