| Abstract: | The process by which reproductive behaviour in the male Gammarus duebeni is evoked has been found to depend upon the reception of a chemical cue from the female. This cue is perceived by receptors on the second antennae and its function is to synchronize mating with the suitable phase of ecdysis in the female. Small concentrations of the surfactant TWEEN 80 are shown to interfere with the reception of this chemical cue, resulting in a decrease in mating success. |
