PhC-SR-μCT is a nondestructive technique that allows the microanatomical investigations and 3D images reconstructions. This technique is performed in blood sucker, Rhodnius prolixus--one of the most important insect vectors of Trypanosoma cruzi, ethiologic agent of Chagas' disease in Latin America--was able to provide excellent information about the microanatomy of the thorax and head allowing a new tool for further studies of development and physiology of triatomine by a non-invasive method of observation.2030-01-01
