Abstract:		"Heterocrossa rubophaga, the raspberry bud moth, is a pest of commercial Rubus berry crops and wild Rubus species. Its pheromone was initially identified as a single component, (7Z)-nonadecen-11-one. Here we report further investigation of this carposinid pheromone including volatile collection, gland extraction, mass spectrometry, microchemical analysis, electrophysiology and field testing. The alkene (7Z)-tricosene was identified from female gland extracts and the synthetic compound gave antennal responses from the male moth. Field testing of (7Z)-tricosene showed that it was unattractive alone but in combination with (7Z)-nonadecen-11-one it more than doubled male moth trap catch for all doses tested compared to that of (7Z)-nonadecen-11-one alone. We recommend a blend of 300 microg of (7Z)-nonadecen-11-one and 300 microg of (7Z)-tricosene as an improved monitoring tool for raspberry bud moth for use by berry growers. This is the second report of the Z-alkene as a pheromone component in the Carposinidae family among the three carposisnid pheromones identified to date"
