Responses of male California red scale to sex pheromone isomers

The California red scale, Aonidiella aurantii (Maskell), sex pheromone components were previously identified as two independently attractive norsesquiterpenes. The four possible optical isomers of one and the four possible geometric and optical isomers of the other were synthesized and tested for ma...

Description
Summary:	The California red scale, Aonidiella aurantii (Maskell), sex pheromone components were previously identified as two independently attractive norsesquiterpenes. The four possible optical isomers of one and the four possible geometric and optical isomers of the other were synthesized and tested for male California red scale attractiveness in field tests and greenhouse bioassays. The results showed that there was enantiomeric and geometric specificity and only 1 isomer of each component was significantly more active than the others. The active isomers were (3 S,6 R)-3-methyl-6-isopropenyl-9 decen-1-yl acetate and (3 Z,6 R)-3-methyl-6-isopropenyl-3,9-decadien-1-yl acetate. The presence of other isomers, including the synthetic analogue 3-methyl-6-isopropylidene-9-decen-1-yl acetate, had no effect on trap catch.
