Résumé :
A study of the antennae of five species of Coleophoru Hubner, 1822 (Coleophoridae) has been carried out by scanning electron microscope in order to determine the morphological types of sensilla and to compare these results with those obtained for C. obducta (Meyrick). In adult males, eight types of sensilla were observed on the flagellum: uniporous sensilla chaetica, multiporous sensilla trichodea, three types of multiporous sensilla basiconica, multiporous sensilla coeloconica, aporous sensilla styloconica and aporous sensilla squamiformia. In view of their morphology, sensilla chaetica are contact chemoreceptors, sensilla squamiformia are tactile mechanoreceptors, sensilla styloconica are thermo-hygroreceptors, and sensilla trichodea, basiconica and coeloconica are olfactive chemoreceptors. No sensilla placodea have been observed. These results differ partially from those previously described for C. ohclucta in regards to the interpretation of the structure and function of some sensilla
