Fig. 5From: Development and evaluation of mosquito-electrocuting traps as alternatives to the human landing catch technique for sampling host-seeking malaria vectorsAssessment of non-linearity as a measure of density dependence of the electrocuting traps relative to the HLC. Solid lines represent a model of linear relationship between the numbers of mosquitoes collected by a novel trap relative to HLC, while dotted lines were obtained from non-linearity, which was modelled as a natural cubic spline with two degrees of freedomBack to article page
