SUMMARY:Mourad Jaffar-Bandjee (IRBI\, Université de Tours): Odor capture b
 y pectinate antennae - Mourad Jaffar-Bandjee
DESCRIPTION:Mourad Jaffar-Bandjee: In some moth species\, male adults posse
 ss pectinate antennae which detect sexual pheromones emitted by females. A
  critical step in the olfaction process is the capture of pheromone molecu
 les which depends heavily on the shape of the antenna. Pectinate antennae 
 are however difficult to study because they are multi-scale objects spanni
 ng over four orders of sizes\, depending on the structural elements. We fo
 cused on the species Samia cynthia and split its antenna in two levels\, t
 he macro- and the microstructures\, and studied them separately. In both c
 ases\, we used Additive Manufacturing to build artificial scaled up models
  and Particle Image Velocimetry to determine their respective leakiness\, 
 the proportion of flow deflected from an object. We then adapted a heat tr
 ansport model to calculate the mass transport problem of pheromone capture
  by the microstructure. Using FEM simulations\, we combined the two levels
  and determined the capture efficiency of the entire antenna. We compared 
 it with a cylindrical one and showed that a pectinate antenna is a good de
 sign to increase the surface of the antenna without significantly decreasi
 ng the capture efficiency.
