Abstract
At Eielsen Field, Alaska, large-scale spray tests with DDT for the control of mosquito larvae showed that adult mosquitoes infiltrated into an area of 100 sq. mi. within 3 days after they emerged from adjacent untreated areas. When this same area was sprayed to control adult mosquitoes, infiltration was sufficiently great to require another application in about 2 weeks. In the tundra area at Umiat, Alaska, mosquitoes infiltrated into a 16-sq.-mi. area within 13 hours. Formulation studies indicated that a 20% DDT airplane spray could be improved by the use of spreaders or emulsifiers. The tests confirmed that 0.1 lb. of DDT is a practical dosage and that nothing is to be gained by diluting the 20% spray to 5%.Keywords
