dc.description.abstractOn account of vector control being the most successful approach towards prevention of the major arboviral concerns worldwide and the imperative pursuit of alternatives to traditional pesticides, we developed a novel attractive toxic sugar bait (ATSB) device. The device incorporates seemingly inexpensive (cost < 1 USD) olfactory and visual cues attractive to Aedes aegypti L. We incorporated 1% boric acid in 10% sucrose solution as toxic component on the devices and this showed to be effective killing female A.aegypti in controlled laboratory conditions (0% survival probability after 48h). In addition, we evaluated the biological action of the device and concluded that boric acid acts as a stomach poison. Using transmission electron microscopy we further determined that it disrupts the continuity of the epithelial tissue of the posterior midgut. The device is effective poisoning A. aegypti females in two different physiological statuses (recently blood fed and parous). Finally, devices were effective after 180 days of being assembled. These features provide us with information that will be useful for future semi-field and field trials.
