Abstract
Analyses of pheromone gland extract of female satin moths, 'Leucoma salicis', by coupled gas chromatographic-electroantennographic detection (GC-EAD) employing fused silica columns coated with DB-210, DB-23 or DB-5 revealed six antennally active compounds. (3'Z',9'Z ')-'cis'-6,7-Epoxy-heneicosadiene (1) and (3'Z',6'Z')-'cis'-9,10-epoxyheneicosadiene (2) were identified. Of all four stereo selectively synthesized stereoisomers, 'SRSR-4' elicited the strongest antennal response, and by itself attracted male SM, suggesting that it is the major SM pheromone component. Addition of 'SRRS-4' to ' SRSR-4' at a wide ratio, as found in pheromone gland extracts, significantly enhanced attractiveness of 'SRSR-4', further suggesting that 'SRRS-4' is a second pheromone component. For pheromone-based monitoring of SM, a suboptimal but economical mixture of stereoisomers of 4 (in a 1:1:1:1 ratio) is recommended as a trap lure to obtain a correlation of captured males with the actual population density in the sampling area. For development of pheromone-based detection surveys of SM, further testing of 'SRSR-4', ' SRSR-4' plus 'SRRS-4' and stereoisomeric 4 is required. (Abstract shortened by UMI.)
