title: Behavioral effects of secondary components of sex pheromone of western spruce budworm (Choristoneura occidentalis) free.
abstract: In a laboratory wind tunnel, upwind flight and close-range orientation to a pheromone source by maleC. occidentalis were facilitated by the addition of the secondary componentsE/Z11-tetradecen-1-ol acetate (89∶11) andE/Z11-tetradecen-1-ol (85∶15) to low source concentrations of the primary components,E/Z11-tetradecenal (92∶8). Male responses to the blends tested never equalled their responses to virgin females. The primary components alone, when released at a rate similar to that of a "calling" female, never elicited male upwind flight or source location. However, the addition of the secondary components enhanced these behavioral sequences.
