  1. Results are shown for individual compounds per species averaged over male and female beetles, combined for genders and gender-dose interaction, and on compound-solvent comparisons, averaged over doses and male and female beetles
  2. Data have been collected from 62 independent antennae of C. populi (35 females, 27 males) and 26 independent antennae of P. vitellinae (15 females, 11 males)
