This volume includes measures of control of aquatic vegetation that harms human
health, since water-related diseases exist in this environment. Although malaria has
receded internationally due to the combined chemotherapeutic-insecticidal programs,
recently it has resisted both medicines and insecticide control. Active malaria cases in
the U.S. were fewer than a dozen before the Vietnam War, but in 1973 the figure was
about 700, almost all traceable to returning military personnel. The disease could again
become prevalent. Other diseases exist whose transmission is indirectly affected by
aquatic weed conditions including filariasis, and various trematodiases, especially from
the schistosomes, Chinese liver fluke, cattle liver fluke, Guinea worm, giant intestinal
fluke, Asiatic lung fluke, and broad tapeworm. Waterweeds also support disease-pest
arthropods, i.e., snipe flies, tabanids (horse, gad, deer, and greenheads), Clear Lake
gnats, May flies, black flies, sand flies, and sewage flies.
Ecosystem studies of impounded water research and development of herbivorous
fish, and utilization of herbivorous fish in China, are also included in this volume.
