Abstract

Publisher Summary This chapter discusses chemical communication in helminthes. Chemical communication is ubiquitous in the animal kingdom and has been studied extensively in insects. Chemical communication between male and female schistosomes has been demonstrated in vitro by Imperia. The chapter examines chemical communication in pre-adult and adult helminths––that is, how helminths communicate with each other using chemical signals. Information on host location by helminths is reviewed and can be considered as it relates to worm-mediated chemical communication. Most of the literature on chemical communication in helminths concerns free-living and parasitic nematodes and digenetic trematodes. The chapter describes terminology used in chemical communication, in vitro and in vivo bioassays, specific structures involved in the production and release of pheromones, chemoreception, and analytical techniques used for studying pheromones. It also discusses helminths in general and then specifically those organisms that have been studied extensively.
