A female-produced sex pheromone for the pecan nut casebearer, Acrobasis nuxvorella Neunzig, has been identified from pheromone gland extracts of calling female moths. The compound (9E,11Z)-hexadecadienal [(9E,11Z)-16:Ald] was identified by coupled GC-EAD and retention time matches with a synthetic standard on four capillary GC columns of different polarities. Corroboration of the identification of (9E, 11Z)-16:Ald by other analytical chemistry methods was not possible due to the minute quantities of pheromone extracted (<1 picogram/female). In field studies, gray rubber septa impregnated with 100 mu g of synthetic (9E,11Z)-16:Ald were attractive to male moths, whereas higher and lower doses were less attractive. The homologous (9E,11Z)-15:Ald was also slightly attractive, while the more highly conjugated analogues, (9E,11Z,13Z)- and (9E, 11Z,13E)-16:Ald, were not. Copyright (C) 1996 Elsevier Science Ltd
