The 10th International Symposium On Phlebotomine Sandflies (ISOPS) was held on the 15 – 19 July 2019 on the beautiful island of San Cristobal, Galapagos. Organised by the Institute of Microbiology at San Francisco de Quito University (USFQ), the conference addressed topics including: modern tools for sandfly studies, ecology and epidemiology, systematics and phylogeny, vector and parasite interactions, and sandfly control. Over 80 delegates attended, from 21 countries, with a total of 51 talks and 45 posters presented across the week. Gnatwork Co-Director, Professor Mary Cameron, and Network Manager, Dr Emma Howson, attended the conference to present the Gnatwork to the ISOPS community. We really enjoyed meeting the sandfly community and hope to see a number of you at our second international workshop in Belo Horizonte, Brazil.
