This study aimed to assess the efficacy of the Sterile Insect Technique (SIT) against <jats:italic>Aedes albopictus<\/jats:italic> (Skuse), the predominant dengue vector in the country, through a pilot field trial of an Integrated Vector Management (IVM) strategy including the SIT. The pilot trial was conducted in the Gampaha district, which reports the second-highest number of dengue cases in the country. A total of 3,300,000 sterile males, exposed to a 50\u00a0Gy radiation dose, were released over 33 weeks (100,000\/week) within a 30-hectare release area. Entomological assessments were conducted at 115 trapping stations over a period of 71 weeks (October 2020\u2013August 2022). Induced sterility of 98.16% in mosquito eggs was reached within the release area as compared to the control area (binomial generalized linear mixed model, deviance 2.408, df\u00a0=\u00a02, <jats:italic>p<\/jats:italic>\u00a0=\u00a00.016), indicating a notable impact of the SIT. The trial achieved nearly 98% suppression of adult vector mosquitoes, with a sustained suppression effect for 13 weeks post cessation of releases. These findings suggest that SIT can be effectively integrated as a potential additional tool into the future IVM strategy in Sri Lanka.<\/jats:p>","DOI":"10.1051\/parasite\/2025050","type":"journal-article","created":{"date-parts":[[2025,9,17]],"date-time":"2025-09-17T07:58:51Z","timestamp":1758095931000},"page":"59","source":"Crossref","is-referenced-by-count":3,"title":["Suppression of <i>Aedes albopictus<\/i> in Sri Lanka using the Sterile Insect Technique (SIT) with a sustained effect"],"prefix":"10.1051","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8300-9849","authenticated-orcid":false,"given":"Menaka","family":"Hapugoda","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2528-4236","authenticated-orcid":false,"given":"Nilmini Silva","family":"Gunawardene","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9078-1968","authenticated-orcid":false,"given":"Tharaka","family":"Ranathunge","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5115-5788","authenticated-orcid":false,"given":"Sudath","family":"Samaraweera","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9905-1948","authenticated-orcid":false,"given":"K.","family":"Karunathilake","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0006-5212-4250","authenticated-orcid":false,"given":"Bazoumana B.D.","family":"Sow","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7393-4670","authenticated-orcid":false,"given":"Gayan Parakrama","family":"Withanage","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Indika","family":"Weerasinghe","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8662-4700","authenticated-orcid":false,"given":"Hamidou","family":"Maiga","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1913-416X","authenticated-orcid":false,"given":"Jeremy","family":"Bouyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"250","published-online":{"date-parts":[[2025,9,17]]},"reference":[{"key":"R1","unstructured":"Annual health bulletin. 2019.
