Mean EAG and EPG amplitudes for recordings on antennae

<p>(<b>blue bars</b>)<b>, maxillary</b> (<b>pink bars</b>) <b>and labial palps</b> (<b>green bars</b>) <b>from third instar </b><b><i>M. melolontha</i></b><b> larvae whole-body mounts</b> (<b>n = 15 replicates on 6 animals</b> (<b>1–3 per animal</b>))<b>.</b> Response to respective controls (empty pipette, DCM, dist. water and DCM supplemented by 20% water) has been subtracted. The grey bars behind colored bars display gross responses without solvent correction. Asterisks indicate significantly higher responses to the tested compound than to respective solvents (Welch two sample t-tests with sqrt transformed data). Significance levels: *** at p<0.001; ** at p<0.01 and * at p<0.05. A: alcohols, ketones and aldehydes at a concentration of 1µg/µl in DCM. B: Undiluted compounds, stimulation with empty pipette and CO₂, C: Amines, esters at a concentration of 1µg/µl in DCM and acids at the same concentration in DCM supplemented by 20% dist. water. D: Monoterpenes, sesquiterpenes and solvents at a concentration of 1µg/µl in DCM.
