Pheromone components previously identified in various lymantriid moths were field tested in a trapping experiment near Padang, West Sumatra, Indonesia. Each of ten experimental replicates, consisting of four sticky traps, were deployed in complete randomized block and baited with one of four synthetic pheromone lures. Most interesting results include: (1) significant captures of male Lymantria brunneiplaga in traps baited with (+)- and (-)-xylinalure [(7R,8S)- and (7S,8R)-cis-7,8 epoxy-2-methyleicosane]; and (2) capture of male Lymantria subrosea singapura in traps baited with (+)-disparlure [(7R,8S)-cis-7,8-epoxy-2-methyloctadecane], (+)-monachalure [(7R,8S)-cis-7,8-epoxy-octadecane] and 2-methyl-Z7-octadecene. These results will allow an improve pheromone-based monitoring of L. brunneiplaga and L. subrosea singapura, respectively. Future studies should attempt to obtain virgin female moths of respective species for thorough laboratory analyses and field testing of candidate pheromone components. Males of L.beatrix (2) and Lymantria narindra (1) also responded to (+)-disparlure baited traps.
