Dr Hélène DELATTE (HDR) is a researcher in CIRAD’s PVBMT unit, based in the French overseas territory of Réunion. She obtained her Master’s degree in Crop Science in 2001 and her PhD in 2005 from Wageningen University (Netherlands). She was an associate professor at the University of La Réunion and worked on whitefly species as vectors of plant viruses with Pr B. Reynaud until 2006. She then worked on Aedes albopictus, a mosquito vector of arboviruses among which chikungunya and dengue, with Dr D. Fontenille at the IRD from 2006 to 2008. In 2008, she joined the CIRAD research Centre (PVBMT unit on La Réunion) as a permanent researcher. Since then, her research has focused on understanding the evolutionary and ecological processes of invasion of tropical crop pests and how to prevent future invasions. Her models of interest are mainly focused on tropical pests of the families Tephritidae and Aleyrodidae. She also works on the bioecology and genetic diversity of beneficial insects such as the Honeybee. Most of her research is developed in collaboration with Indian Ocean, Central and East African countries. Although her main unit is based in La Réunion, she has been hosted from 2020 to 2023 by the FOFIFA research Centre in Antananarivo (Madagascar). She has supervised more than 15 PhD students and several MSc students, published more than 120 scientific papers and a book on the diversity of frugivorous fruit flies and their host plants in the islands of the Indian Ocean. She is currently Head of the Ecology Department in her research unit. She is also the coordinator of the dP biocontrol-OI, a network, which links the main research institutions and crop protection agencies of the Indian Ocean countries on common issues related to plant epidemiological surveillance and biocontrol solutions (https://www.dp-biocontrole-oi.org/).
