Some Factors that Influence Egg Hatch of Aedes aegypti (Diptera: Culicidae)

Abstract

To determine the effects of drying, flooding, and water temperatures on egg hatch of the yellow-fever mosquito, Aedes aegypti (L.), eggs on roughened aluminum paddles were placed daily for 169 days just above the water level in glass containers in the sun and shade, and daily larval counts were made.

By daily measurement of the water level in a standard container, the “hatch indicator,” the combined effects of rainfall and evaporation were determined, and these measurements provided an estimate of the production of A. aegypti from discarded open-topped containers in the field.
