List of all tested plant extracts (leaves and flowers) for Nepeta and Actinidia species. Names of each species and variety that were tested, across both catnip (Nepeta) and kiwifruit (Actinidia) genera. While catnip varieties produced large amounts of unidentified isomers of nepetalactone, they did not generate any isomers of the behaviorally active compounds of interest. However, each species and genotype of kiwifruit produced one or several isomers of the parasitoid odors; moreover, leaf materials always contained larger amounts of the odors as compared to flowers. One species, Actinidia polygama, consistently produced the largest amount of our compounds of interest, and represents the best target for additional study of these iridoid odors, including the natural product that is the namesake of this genus of plant, actinidine. (− = odor was not detected by GC-MS; trace = threshold levels detected; + = low amounts detected; ++ = moderate amounts; ++++ = highest amounts of major iridoid components found)
