Eave tubes for malaria control in Africa: an introduction

Area of Science:

• Medical Entomology
• Vector-Borne Disease Control
• Product Development

Background:

• Malaria control requires new tools beyond long-lasting insecticide-treated nets (LLINs) and indoor residual spraying (IRS) due to insecticide resistance.
• Existing methods face challenges in achieving malaria elimination goals.
• Novel strategies are essential for effective insecticide resistance management.

Purpose of the Study:

• To present the development and evaluation of a novel malaria vector control concept: the 'eave tube'.
• To assess the potential of eave tubes as a viable, cost-effective, and acceptable tool for malaria vector control.
• To explore the applicability of eave tubes across diverse housing structures in sub-Saharan Africa and beyond.

Main Methods:

• Conceptualization and design of the eave tube device.
• Laboratory and semi-field testing of eave tube efficacy.
• Evaluation of implementation potential and cost-effectiveness.

Main Results:

• Eave tubes demonstrated potential as a novel delivery system for insecticides and house screening.
• The approach showed promise for controlling endophilic and endophagic anopheline mosquitoes.
• The method is adaptable to various housing types, particularly those with eave entry points for mosquitoes.

Conclusions:

• Eave tubes represent a viable, cost-effective, and acceptable supplementary tool for malaria vector control.
• This innovative approach can contribute to insecticide resistance management strategies.
• The eave tube has broad applicability for controlling mosquitoes, including malaria vectors, in diverse settings.
