Preference of blood-fed females from brackish and fresh water- derived <i>Ae. aegypti</i> for oviposition on brackish and fresh water surfaces.

The results are the mean number of eggs laid in the two types of surfaces ± standard deviation in the three separate experiments. A two-tailed unpaired Student's t test was performed to determine the probability of significant differences in the mean number of eggs laid by females of each colony on brackish and fresh water surfaces. The brackish and fresh water colonies were derived from Ae. aegypti collected in Kurunagar and Thirunelvely respectively in the Jaffna peninsula.
