A method of separating ZE-nepetalactone and EZ-nepetalactone from catnip oil involving mixing catnip oil dissolved in at least one water immiscible, non-halogenated organic solvent with at least one inorganic base dissolved in water to form a biphasic mixture, stirring the biphasic mixture to hydrolyze ZE-nepetalactone to form ZE-nepetalic acid, separating the aqueous phase containing ZE-nepetalic acid from the organic phase containing EZ-nepetalactone in the biphasic mixture, and optionally acidifying the aqueous phase to about pH 4. 5 and adding at least one water immiscible, non-halogenated organic solvent to azeotropically lactonize the ZE-nepetalic acid in the presence of a catalytic amount of p-toluene sulfonic acid to form ZE-nepetalactone.

Compositions and methods are provided for attracting and subsequently trapping and/or killing adults of the Asian longhorned beetle, Anoplophora glabripennis, or interfering with their reproduction. The aggregation pheromones, 4-(n-heptyloxy)butanal and 4-(n-heptyloxy)butan-1-one, in combination with a trap or toxicant, provide means for monitoring, killing or inhibiting the reproduction of these insects.
