Summary

From June 15 through September 11, 1964, about one percent of the premises in 639 counties of 11 southeastern states were inspected for domestic mosquitoes by 7 teams totaling 45 men. Infestations of Aedes aegypti were found in 566 communities of 203 counties. A solid block of counties in southern Alabama, and the neighboring areas of Georgia, Florida, and Mississippi were found to have extensive urban and rural infestations. In the remaining portions of Florida and Georgia, in all of South Carolina and in eastern Texas, the infestations were more scattered and usually limited to the central city of the county. Infestations were found in only one or two counties of Arkansas, Louisiana, North Carolina, and Tennessee. No infestations were found in Oklahoma. The 1964 survey added 479 communities and 125 counties to the list of known infestations.

Questionnaires were sent to 2,348 laboratories: 1,383 respondents indicated that they are neither using nor planning to use Ae. aegypti; 63 laboratories maintain permanent colonies; 47 make periodic use of the species.
