Principle and model of the T-Net. (a) Picture of experimental huts in the region of Tiassale in Cote d’Ivoire (Africa), where the field trials were conducted; (b) schematic of the hut and the T-Net deployed in the hut; (c) schematic of the mosquito flight track in the hut; (d) unit area on the bottom of the T-Net cone that captures the mosquito; (e) predicted capture number for Gen1, Gen2, and Gen3 T-Nets (see Figure 2a–c, respectively) with an uncertain number of mosquitoes flying into the hut; and (f) the predicted capture number for Gen1, Gen2, and Gen3 T-Nets when hut volume increases and the number of mosquitoes flying into the hut is constant.
