Novel Components of the Sex Pheromones Produced by Emerald Moths: Identification, Synthesis, and Field Evaluation
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.
(6Z,9Z,12Z)-6,9,12-Octadecatriene and (3Z,6Z,9Z,12Z)-3,6,9,12-icosatetraene, the novel sex pheromones produced by emerald moths

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.
Sex Pheromone Components and Control of the Citrus Pock Caterpillar, Prays endocarpa, Found in the Mekong Delta of Vietnam
The citrus pock caterpillar, Prays endocarpa (Yponomeutidae; Praydinae), is a pest of pomelo (Citrus grandis L.) in Vietnam and the potential for pheromone-based control of this pest is demonstrated.
7,11,13-Hexadecatrienal identified from female moths of the citrus leafminer as a new sex pheromone component: synthesis and field evaluation in Vietnam and Japan
The results indicated that the sex pheromone of the Vietnamese strain is similar to that of Brazilian and Californian strains, but the Japanese strain has established a different communication system from those of the foreign strains.

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
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.

It was concluded that the S. astaurota females secreted (9Z,11Z)-9,11-tetradecadien-1-ol (Z9,Z11-14:OH) as a main pheromone component, and the acetate and aldehyde derivatives as minor components, and this identification was confirmed by a field evaluation of the synthetic phersomone.

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.
