✦ Synopsis

The behavioural significance of (Z)-9-tetradecenal to male H. assulta was tested by comparing the number of moths attracted to lures containing a standard synthetic female sex pheromone with lures in which (Z)-9-tetradecenal was also added. The standard pheromone mixture used contained 1000lag (Z)-9-hexadecenal, 50 lag (Z)-ll-hexadecenal, 300 lag (Z)-9-hexadecenyl acetate and 15lag (Z)-ll-hexadecenyl acetate impregnated on rubber septa. Addition of (Z)-9-tetradecenal to the standard pheromone was shown to significantly reduce the caught of male H. assulta when added in amounts greater than 10 tag or 1% of the major pheromone component in both field and net-house experiments. The reduction in catch was found to be dependent on the quantity of (Z)-9-tetradecenal added to the standard pheromone. The implications of these results on conspecific and interspecific pheromone-mediated communication in H. assulta and related sympatric heliothine species is discussed.
