Fig. 11. Summarized effects of putative transmitters on algal intake of I.
obsoleta larvae expressed as percentage of the control (100%). Tested
compounds included serotonin (from 10-4 mol l-1 to
10-6 mol l-1), dopamine and norepinephrine (from
10-4 mol l-1 to 10-6 mol l-1).
Asterisks indicate significant difference when compared with the control group
(P<0.05).
