LC₅₀ for salinity tolerance of <i>Aedes aegypti</i> colonies.

LC50 is the salt concentration in parts per thousand (ppt) that results in 50% mortality in the transition from first instar larvae to adults.The 95% confidence intervals of the LC50 values are shown in parentheses. The original brackish and fresh water colonies were derived from Ae. aegypti collected in Kurunagar and Thirunelvely respectively in the Jaffna peninsula.
