| Abstract: | "Our objective was to identify the sex pheromone of Lymantria lucescens and Lymantria serva (Lepidoptera: Lymantriidae), whose larvae defoliate, respectively, Quercus spp. in temperate regions and Ficus spp. in the subtropics. Coupled gas chromatographic-electroantennographic (GC-EAD) detection analyses of pheromone gland extracts revealed one EAD active compound produced by female L. lucescens and by female L. serva. This was identified as 2-methyl-(Z)-7-octadecene (2me-Z7-18Hy) by retention index calculations on DB-5, DB-23, and DB-210 columns and by comparative GC-mass spectrometric (MS) and GC-EAD analyses of the insect-produced candidate pheromone and synthetic 2me-Z7-18Hy. In field experiments, traps baited with 2me-Z7-18Hy captured male L. lucescens near Toyota City, Japan, and male L. serva in Taipei, Taiwan. Allopatric distribution of L. lucescens and L. serva seems to allow both species to use the same sex pheromone without compromising its specificity" |
