Example survivorship curve (A) and mortality rate (B; see Materials and methods) showing that human insulin provided in sucrose increased the mortality of A. stephensi relative to controls. These plots correspond to the data for experiment 2, Table 1. Female mosquitoes were provided with 10% sucrose-soaked cotton pads with 1.7×10⁻⁴ μmol l⁻¹ human insulin or with an equivalent volume of insulin buffer as a control in sucrose. Cotton pads were changed twice daily. Dead insects were counted and removed daily from treatment and control cartons.
