Evaluation of attractive toxic sugar bait resting place against dengue vectors in urban Tanzania

Fighting against dengue vectors using the current successful vector control tools (Long Lasting Instecticidal Nets and indoors Residual Spray) faces physiological, operational and financial challenge such as emergence of insecticide resistance, vectors biting time and economic constrains.

This underlines the importance of investigating new control intervention against Ae aegypti (dengue vector) which will synergistically work with the present control tools.

We therefore propose to investigate if Aedes mosquitoes can be attracted to attractive toxic sugar baited resting places and tempt to feed on a sugar concoction contain toxic ingredient (ivermectin) A series of experiments will conducted in IHI laboratory to determine the dose required to kill 90% of Aedes followed by determination of Aedes response to sugar baits even if the host is constantly made available in semi field system. We will also conduct a small field trial study to evaluate the effectiveness of the tool against wild Aedes.#
