motor incoordination; convulsions; and depressed population densities of
aquatic invertebrates.

Three courses of action are recommended. (1) Restrict the use of
chlorpyrifos for mosquito control in wetlands, estuaries, and waterfowl
breeding areas because recommended treatment levels are demonstrably harmful
to nontarget resident biota. (2) Curtail agricultural use in watershed areas
pending acquisition of additional data on chlorpyrifos toxicokinetics. (3)
Develop suitable replacements for chlorpyrifos in mosquito control programs;
specifically, pesticides with more specificity to target organisms, and lower
toxicity to nontarget biota.
