And finding a suitable host will a have positive impact on reproduction, as blood components are essential for the development of eggs. A number of studies evaluating putative attractants or repellents to mosquitoes and their odor-mediated orientation responses usually employ commercial or “home-made” olfactometers of variable complexity. In order to fulfill most external cues needed for studying mosquito behavior, this equipment usually has a flight chamber, tubes and connections, temperature\/humidity control, filters, a pump to generate and control airflow, and other devices. Despite their attested effectiveness in evaluating mosquito responses, the cost involved in the production or acquisition of all these components is prohibitive for researchers from poor countries. In addition, given the size and shape of this kind of equipment, special requisites are needed for its storage and transportation. Blood meal identification is another important aspect to understand host preference and the chemoreceptive nature of mosquito behavior. A number of serological and non-serological procedures have been employed to identify the blood source, the precipitin test being the most widely used by far. Nevertheless, some of these procedures present inconsistent degrees of specificity and sensitivity, and some others are complex and require laboratory reagents that need to be refrigerated, another limiting factor for groups with limited financial resources. On the other hand, the evaluation of mosquito preferences toward two or more known individual hosts seems more attainable, however, a GS-5734 AbMole<\/a> convenient method to assess this information is still lacking. All these things considered, studies of mosquito attractiveness or repellency would benefit from a simpler, spaceless and low-cost method able to discriminate mosquitoes choice toward small vertebrate hosts submitted to different treatments, experiences or situations, placed side by side either in closed or open environments. By using a well-known vital dye, Evans blue, together with standard and affordable laboratory supplies, we standardize and validate here a methodology to evaluate the source of a mosquito’s blood meal when exposed to two alive feeding options under the same conditions. We also tested if our simple method would be efficient enough to evaluate repellency. Another side by side testing was performed using a commercial repellent brand that had its efficacy confirmed, either visually or spectrophotometrically. This assay was carried out as a proof of concept only and for this reason no other parameters associated with repellency were assessed, such as time of protection or number of bites received throughout longer periods of time.<\/p>\n","protected":false},"excerpt":{"rendered":"
