Identification of the sex pheromone of the lesser date moth, Batrachedra amydraula, using sequential SPME auto-sampling

The sex pheromone of Batrachedra amydraula, (4 Z,7 Z)-4,7-decadien-1-yl acetate, 4 Z-decen-1-yl acetate, 5 Z-decen-1-yl acetate, and decan-1-yl acetate is identified from sequential SPME/GC–MS samplings of volatiles released by virgin females. The identification of the sex pheromone of the lesser da...

Description
Summary:	The sex pheromone of Batrachedra amydraula, (4 Z,7 Z)-4,7-decadien-1-yl acetate, 4 Z-decen-1-yl acetate, 5 Z-decen-1-yl acetate, and decan-1-yl acetate is identified from sequential SPME/GC–MS samplings of volatiles released by virgin females. The identification of the sex pheromone of the lesser date moth, Batrachedra amydraula (Meyrick) was based on GC–MS analysis of volatiles released by virgin females using sequential SPME auto-sampling of headspace and by synthesis of the key component, (4 Z,7 Z)-4,7-decadien-1-yl acetate. Substantial capture of males in a date palm plantation using a bait consisting of the key component and 5 Z-decen-1-yl acetate in a ratio of 1:2 indicated that these are the essential components of the sex pheromone. Addition of 4 Z-decen-1-yl acetate and decan-1-yl acetate, which were also identified, did not affect trap-capture. The lesser date moth is the first member of the Batrachedridae whose sex pheromone has been identified. (4 Z,7 Z)-4,7-Decadien-1-yl acetate is a novel compound among moth sex pheromones.
