Odour-mediated oviposition site selection in Aedes aegypti depends on aquatic stage and density.

ABSTRACT:

Background

Olfaction plays an important role in the selection and assessment of oviposition sites by mosquitoes. Volatile organic compounds (VOCs) associated with potential breeding sites affect the behaviour of gravid mosquitoes, with VOCs from aquatic stages of conspecific mosquitoes influencing and regulating oviposition. The purpose of this study was to conduct a systematic analysis of the behavioural response of gravid Aedes aegypti to conspecific aquatic stage-conditioned water, to identify the associated bioactive VOCs and to determine how blends of these VOCs regulate oviposition site selection and stimulate egg-laying.

Methods

Using a multi-choice olfactory oviposition assay, controlling for other sensory modalities, the responses of individual females to water cond
