Extract

Disruption of mating and of trap capture of spruce budworm, Choristoneura fumiferana (Clem.), has been accomplished in recent years (reviewed in Silk and Kuenen 1984) by disseminating large quantities of the primary components (synthetic) of the female sex pheromone within a forest environment. These components (E)- and (2)-11-tetradecenal (E/Z11-14:Ald) (Sanders and Weatherston 1976) are emitted by virgin female budworm at a 95/5 E/Z ratio (Silk et al. 1980). Unsaturated aldehydes are expensive, tend to polymerize readily (Dunkelblum et al. 1984), and are susceptible to air oxidation and/or photodegradation in the field environment. Analogues, with increased stability and reduced cost, that duplicate the effects of these pheromone components would therefore be of practical value.
