All nine compounds shown have been used as electrophysiological and/or behavioural stimuli in the present study. Note that some compounds are duplicated for more than one species.

The table also shows the ratios at which the compounds have been found in females of the respective species (ratios only valid within species). Relative amounts are based on the 50 μg+50 μg loads of the major pheromone components of E. semipurpurella used for field-trapping in the present study.
