In this study, sugar-feeding was investigated as a possible means of re-introducing bacteria into mosquito midguts with the aim of identifying bacteria that are suitable for creating paratransgenic mosquitoes. In a paratransgenic approach, bacteria are utilised to deliver effector molecules capable of inhibiting pathogen development in the midgut of the vector. To determine if mosquitoes discriminate between sterile sugar solutions and sugar solutions with bacteria, a method for screening mosquito feeding preferences was developed. This method was tested for Aedes aegypti, Anopheles arabiensis and An. gambiae s.s. mosquitoes and is based on a dual-choice test of solutions labelled with food dyes. Three different tests (dye/colour detection, sugar detection and sugar-concentration detection) were performed to evaluate the method, after which bacteria previously isolated from mosquitoes were used in the experiments. It was shown that mosquitoes do not discriminate between sugar solutions with or without these bacteria indicating that sugar-feeding is a possible means to introduce bacteria into mosquitoes. Furthermore, two different setups of the method were used, enabling us to differentiate between tactile/taste and olfactory responses. The method described in this paper is easy to use, cost-effective and allows broad screening of mosquito sugar-feeding preferences.
