Le contrôle de la population de moustiques

ILM at a glance

Institut Louis Malardé (ILM) is French Polynesia’s public research institution. Based in Tahiti, ILM originates from an initiative launched in 1949 by William Albert Robinson, an American naval engineer, navigator and writer, in his attempt to fight lymphatic filariasis, a mosquito-borne disease which affected many Tahitian homes. Over the past 70 years, ILM has worked to improve and preserve the health, and well being of Pacific Island communities and their environment, with a focus on clinical diagnosis, non-communicable diseases (diabetes), food safety, mosquito vectors and the infectious diseases they transmit (dengue, Zika, chikungunya, lymphatic filariasis, etc).

Update : 2024

Over the past decade, Institut Louis Malardé has engaged in various field evaluation of innovative “Rear & Release” mosquito control strategies such as the Incompatible Insect Technique (release of Wolbachia-carrying male mosquitoes that sterilize their female counterpart in infested areas): from a limited-scale, feasibility trial on a motu of Raiatea to the largest field evaluation completed to date in French Polynesia on the atoll of Tetiaroa. An initial 12 months intervention was carried out in 2015-2016 which resulted in the successful suppression of Aedes polynesiensis on motu Onetahi (ca. 1 sq. km).

Preventative male mosquito releases have been performed since (except during the COVID crisis) to keep the mosquito nuisance at bay on the resort. Mosquito monitoring performed throughout the motu in 2023 indicates a successful suppression with only a few residual foci remaining.

Planning by Tetiaroa Society and Institut Louis Malardé began in 2023 to prepare for a larger scale-deployment targeting mosquito elimination across the entire atoll in the years to come. This Tetiaroa Atoll Mosquito Elimination (TAME) project will contribute fundamental baseline data (including spatial mosquito population genomics analysis) and knowledge necessary to control mosquito populations at scale. Importantly, this will include outreach to the hotel guests and local communities including educational information about the challenges and opportunities of innovative mosquito control. The project will leverage ILM’s new INNOVENTOMO male mosquito factory, an infrastructure unique in France and the Pacific, developed for the mass-rearing and release of sterile male mosquitoes to further explore the feasibility and sustainability of island-wide mosquito elimination.

Nos éfforts de conservation englobent le monitoring, la préservation, les programmes de restauration liés à la biodiversité marine et terrestre des îles tropicales et à la préservation de l'héritage culturel. Tetiaroa Society sponsorise un projet de l'institut Louis Malarde qui explore des méthodes innovatrices, plus éfficaces et plus sûre pour l'environnement pour contrôler la population de moustiques.
