Egg hatching inhibition: field evidence for population regulation in a treehole mosquito

Abstract

ABSTRACT. 1. We investigated the influence of larval density on egg hatching in the treehole mosquito, Aedes triseriatus Say (Diptera: Culicidae) by submerging laboratory‐produced egg batches in natural habitats stocked with fixed densities of larvae. 2. We found a significant decrease in hatching rate as larval density increased. The results suggest that inhibited eggs refrain from hatching into environments in which competitive effects of large larvae are potentially severe, and in which cannibalism may occur. 3. The amount of time the egg batches were exposed to experimental conditions (between 2 and 16 days) had no significant influence on hatch rate. Copyright © 1987, Wiley Blackwell. All rights reserved
