DDT, heptachlor, and malathion emulsions at 1, 3, and 6 pounds of technical material per surface acre were used in tests for the control of mosquito larvae in log ponds in the general vicinity of Corvallis, Oreg. Protection against reinfestation ranged from 3 to 6 weeks for DDT, 5 to 10 weeks for heptachlor, and 2 to 6 weeks for malathion. Culex pipiens L. was the dominant species in ponds in June and July; C. stigmatosoma Dyar predominated in August, September, and October. Except in the cooler months from October through May, Culex tarsalis Coq., C. territans Walker, and Culiseta incidens (Thompson) were represented by relatively small percentages.
