The Life Table Characteristics of a Selected Laboratory Population of Aedes aegypti (L.)

Abstract

The fate of 1103 eggs representing 12 Aedes aegypti (L.) was studied to determine life table characteristics
under laboratory conditions. Real development mortality was low (9.8%) with death during the larval instars
accounting for 80.7% or 7.9% of all development mortality. The length of the life cycle with 8.5 days, with
the larval duration taking 6.5 days.
The sex ratio at emergence was close to 56% males. This value is similar to that found during studies on
sex ratio trends by Craig et al. (1960).
The mean observed fecundity of Ae. aegypti under laboratory conditons was 91.9% +- 17.4 eggs. The
implications for vector supression programs are discussed.
