Studies on the Biology of the Tube-Building Amphipod Microdeutopus gryllotalpa. A Model for Marine Fouling Processes

摘要

The principal objective of the proposed studies was to observe the reproductive biology of Microdeutopus gryllotalpa, with an eye toward devising an effective biological method for controlling fouling. Observations on this and seven other species were conducted. The information obtained covers a wide area, and has provided data for at least nine papers; three published, two in press, and four in preparation. The most important contribution of these studies has been the development of a reliable, objective bioassay for water-borne pheromones, and its use to establish the existence of these substances in two species. It is now possible to conduct studies directed toward determining the chemistry of these substances. Once determined, it may become feasible to synthesize it in sufficient quantities to be employed to lure males to an underwater trap.
