BIOLOGICAL ACTIVITY OF (E,E)-9, 11-TETRADECADIENAL AGAINST MALE SPRUCE BUDWORM, CHORISTONEURA FUMIFERANA (LEPIDOPTERA: TORTRICIDAE)
Published online by Cambridge University Press: 31 May 2012
Extract
Priesner (1979) reported five types of receptor in the trichoid sensilla on the antennae of male spruce budworm, Choristoneura fumiferana. One responded maximally to (E)-11-tetradecenal (Ell-TDAL), the primary component of the natural sex pheromone (Sanders and Weatherston 1976). Two other receptors showed maximum response to (E)- 11-tetradecen-1-yl acetate (E 11-TDACET) and (E)- 1l-tetradecen- 1-ol (E11-TDOL), respectively, both of which are present in female glands, but neither of which has been found in significant amounts in the emitted pheromone. The other two receptors showed maximum responses to (E)-9-tetradecenal (E9- TDAL) and (E,E)-9, 11-tetradecadienal (E9, E 11-TDDAL), respectively, neither of which has been reported from gland extracts or the emitted pheromone.
