Full textIn many moth species, female adults release tiny amounts of sexual pheromone in order to attract male mates and reproduce. The quantity of released pheromone is around a few dozens of nanograms and male moths can detect it a few hundred meters away from females. As a consequence, they must be able to smell very low concentrations of pheromone. This olfactory function is carried out by the antennae. A critical step in the olfactory process is the capture of molecules from the air. This is a mass transport problem which depends heavily on the shape of the antenna. One of the most spectacular shapes, which occurs in several moth families, is the pectinate antenna. This type of antenna is also thought to be more effective at detecting pheromones than cylindrical-shaped ones. In this work, we investigated whether and how the shape of the pectinate antenna influences its efficiency at capturing pheromone molecules. We focused on one species, Samia cynthia.A pectinate antenna is a complex and multi-scale object. It has a length of 1cm and is composed of one main branch, the flagellum, which carries secondary branches, the rami. Each rami supports numerous hairs, the sensilla, which are 150µm long and have a diameter of only 3µm. Thus, the characteristic dimensions of the antenna span over four orders of magnitude, which makes the study of such objects difficult.To simplify our problem, we decided to split the pectinate antenna in two levels: the macrostructure, composed of the flagellum and the rami, and the microstructure, composed of a rami and the sensilla it bears. Both structures were scaled up and fabricated by Additive Manufacturing. The building of the rami and sensilla, which are long and thin cylinders, was a challenge as we reached the limits of the 3D-printers we used.Pectinate antenna are permeable objects, as are the macro-and microstructures. Thus, air flowing in the direction of such objects either passes through the antenna or is deflected around it. Leakiness if the proportion of flow passing through the permeable object. This parameter is important as it sets an upper limit on the pheromone captured by the antenna: molecules carried by the deflected part of the flow cannot be captured. We experimentally determined the leakiness of the macro- and microstructures at several air velocities encountered by a moth in nature using Particle Image Velocimetry.We then calculated the pheromone capture and efficiency of the microstructure by adapting a model of heat transfer to our mass transport problem. We showed that the longitudinal orientation of the sensilla is sufficient to explain the phenomenon of olfactory lens, stating that the tip of the sensilla captures more molecules than the base. We also found that the efficiency of the antenna is limited by both the leakiness of the antenna, which increases with air velocity, and the local capture, which is the proportion of molecules captured in the part of the airflow passing through the antenna and which decreases with air velocity. Eventually, the microstructure does not have a strong maximum efficiency at a specific air velocity but, instead, is moderately efficient over the large range of air velocity encountered by a moth.We developed a method with the help of FEM simulations to combine the two levels (the macrostructure and the microstructure). This method is based on the relation between drag and leakiness and allowed us to determine the leakiness of the entire antenna. We then could calculate the efficiency of the pectinate antenna and compared it with the one of a cylindrical-shaped one. We found that a pectinate design is a good solution to increase the surface contact between the air and the antenna strongly while maintaining a good capture efficiency at the velocities encountered by the moth
