Communication in Invertebrates

Semiochemicals have been identified most extensively in insects. However, the literature suggests that chemical communication may also be used by other invertebrates 98-106, 384-386, 391-401). Primer 

According to Perkins and Fried 102 free sterols and fatty acids may have pheromonal activity in planaria such as Dugesia tigrina and D. dorotocephala. 

Bone (99) argued that the present knowledge of pheromone mediated behavior in helminthes is similar to that of insect communication over 20 years ago. Thus, insect semiochemistry will be discussed here in greater detail.
