Title: Sex pheromone components of pink gypsy moth, Lymantria mathura
Abstract: Pheromone extract of female pink gypsy moth, Lymantria mathura, was analyzed by coupled gas chromatographic-electroantenno-graphic detection (GC-EAD) and coupled CC-mass spectrometry (MS), employing fused silica columns coated with DB-5, DB-210, or DB-23 and a custom-made GC column that separated enantiomers of unsaturated epoxides. These analyses revealed (9R, 10S)-cis-9,10-epoxy-Z3,Z6-nonadecadiene [termed here (+)-mathuralure] and (9S, 10R)-cis-9,10-epoxy-Z3,Z6-nonadecadiene [termed here (-)-mathuralure] at a 1:4 ratio as major candidate pheromone components. In field experiments in northern Japan (Morioka, Iwate Prefecture and Bibai, Hokkaido Prefecture), (+)- and (-)-mathuralure at a ratio of 1:4, but not 1:1 or singly, were attractive to male L. mathura. This is the first demonstration that attraction of male moths required the very same ratio of pheromone enantiomers as produced by conspecific females. Whether L, mathura employ different blend ratios in different geographic areas, and the role of five additional candidate pheromone components identified in this study remains to be investigated.
