The ability to determine the sex of tsetse pupae with the objective to separate the sexes before adult emergence has been a major goal for decades for tsetse management programmes with an SIT component. Tsetse females develop faster and pharate females inside the pupae melanise 1\u20132 days before males. This earlier melanisation can be detected by infrared cameras through the pupal shell, and the newly developed Near InfraRed Pupae Sex Sorter (NIRPSS) takes advantage of this. The melanisation process is not homogeneous for all fly organs and the pupa needs to be examined ventrally, dorsally and laterally to ensure accurate classification by an image analysis algorithm. When the pupae are maturing at a constant temperature of 24\u00a0\u00b0C and sorted at the appropriate age, 24 days post-larviposition for <jats:italic>Glossina palpalis gambiensis<\/jats:italic>, the sorting machine can efficiently separate the sexes. The recovered male pupae can then be sterilised for field releases of males, while the rest of the pupae can be used to maintain the laboratory colony. The sorting process with the new NIRPSS had no negative impact on adult emergence and flight ability. A mean male recovery of 62.82\u00a0\u00b1\u00a03.61% was enough to provide sterile males to an operational SIT programme, while mean contamination with females (4.69\u00a0\u00b1\u00a03.02%) was low enough to have no impact on the maintenance of a laboratory colony.<\/jats:p>","DOI":"10.1051\/parasite\/2023019","type":"journal-article","created":{"date-parts":[[2023,5,17]],"date-time":"2023-05-17T08:21:36Z","timestamp":1684311696000},"page":"17","source":"Crossref","is-referenced-by-count":11,"title":["Near-infrared imaging for automated tsetse pupae sex sorting in support of the sterile insect technique"],"prefix":"10.1051","volume":"30","author":[{"given":"Rafael","family":"Argil\u00e9s-Herrero","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gustavo","family":"Salvador-Herranz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew G.","family":"Parker","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"Zacar\u00e9s","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Assane G.","family":"Fall","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adji M.","family":"Gaye","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Arooj","family":"Nawaz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter","family":"Tak\u00e1\u010d","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marc J.B.","family":"Vreysen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6244-4905","authenticated-orcid":false,"given":"Chantel J.","family":"de Beer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"250","published-online":{"date-parts":[[2023,5,17]]},"reference":[{"key":"R1","doi-asserted-by":"crossref","unstructured":"Aksoy S, Weiss B, Attardo GM. 2008.
