Dengue Prevention and 35 Years of Vector Control in Singapore
Figure 3. Diagrammatic representation of an autocidal ovitrap made up of a black cylinder, a wire mesh on a flotation device, and 2 pieces of cardboard. The gravid female Aedes mosquito lays its eggs on the cardboard. The larvae that hatch from the eggs go through the immature stages of the mosquito's lifecycle, but the resultant adult mosquito will be trapped underneath the wire mesh and drown. Picture inset shows the different components of the ovitrap.
