Abstract [en]

The absolute configuration of the sex pheromone of the Citrophilous mealybug, Pseudococcus calceolariae, has been identified as (1R,3R)-2,2-dimethyl-3-(2-methylprop-1-enyl)cyclopropyl)methyl (R)-2-acetoxy-3-methylbutanoate. The absolute configuration was determined by NMR, derivatization reactions, chiral GC/MS analysis, and comparison with synthetic chiral reference compounds. The correct structure was further proven by trap catches of adult male mealybugs in field trials. Traps baited with 1000 µg of the pheromone caught 36-fold more males than traps baited with virgin females. A mixture of stereoisomers of the pheromone can be used in field trapping experiments. A comparison with the structures of other sex pheromones of mealybugs is presented.
