Evaluation of the major female Eurytoma amygdali sex pheromone components, (Z,Z)-6,9-tricosadiene and (Z,Z)-6,9-pentacosadiene for male attraction in field tests
Journal of Chemical Ecology 30 (6), 1245-1255
Abstract: We evaluated the attraction of male almond seed wasp Eurytoma amygdali to the synthetic alkadienes (Z,Z)-6,9-tricosadiene and (Z,Z)-6,9-pentacosadiene and their blend in almond orchards using baited rubber septa attached to cardboard rectangular adhesive traps. The two alkadienes were recently isolated from virgin female whole body extracts and SPME collected volatiles. The alkenes (Z)-9-tricosene, (Z)-9-pentacosene, and (Z)-9-heptacosene, present in female extracts, were also added to the blend of the alkadienes and tested. The alkadienes tested individually attracted males when the traps were baited with doses ranging from 10 to 30 mg/trap. The maximum number of males was attracted to traps baited with 10 mg of a (Z,Z)-6,9-C23:2:(Z,Z)-6,9-C25:2 blend at a ratio of 7:3. Results with the three alkenes added to the blend were inconclusive because of low populations. The present study on E. amygdali is the first one reporting attraction of males to synthetic sex pheromone components in field trials for a Eurytomidae species. The synthetic alkadienes blend offers the potential to develop an effective system for monitoring populations of the almond seed wasp in almond orchards.
