Summary
In southwestern Georgia observations on the effects of low termperatures on the survival of naturally occurring Aedes aegypti larvae in various types of breeding containers were made throughout the winter. Average weekly air temperatures below 60° F killed most larvae but, because of the sheltered positions of some containers, a few survived during periods when the average weekly temperature was as low as 48° F. During warmer parts of the winter, larval development continued and adults emerged. No indications of feeding or oviposition were observed during the colder months. In the area studied, normal breeding and oviposition apparently commenced during May.
