Fig. 9

Diagrammatic depiction of the possible effects on mosquito near-net behaviour seen from the head end of the occupied bed net of still air in cool conditions. Mosquitoes’ near-net activity occurs largely on the net roof under the unperturbed influence of the rising odour plume. CPU fan is off. Cameras are above and to the left of the net, CPU fan is to the right of the net. Note that this diagram is meant to illustrate possible influences on mosquitoes and is not meant to capture the complexities of shape and internal dynamics of actual plumes
