Background: Mosquito control programs are challenged by mosquito-borne diseases such as malaria, insecticide resistance, and environmental impact on non-target organisms. To address this situation, Target Malaria consortium is in the process of developing a genetic tool that will control malaria mosquitoes Anopheles and that may have little or no impact on non-target organisms. A census or mapping of all non-target organisms in the breeding sites is therefore necessary at this time at our study sites. The objective of our study is to obtain information on the presence of non-target organisms sharing the same larval habitat and, where possible, their ecological relationships with the target mosquito species.

Methods: Larval habitats sampling was conducted during our monthly field surveys started in 2017 and is still ongoing at our Souroukoudingan and Bana sites in western Burkina. Sampling consisted of collecting with a sieve any living organism from about twenty larval habitats and keeping them in 90% alcohol. Identification (Jean-Luc Gattolliat) then allowed us to determine the order and family of each invertebrate collected.

Results: After identification, results showed that the different larval habitats sampled were composed of several orders and families at all sites. The Holometabole Coleoptera order and Dytiscidaes family were the most represented while the Paurometabole Odonata order and Anisoptera Libellulidae family were the least represented at both sites.

Conclusion: These results could constitute a mapping of all non-target organisms existing on our sites currently and could inform us on a probable impact of the use of genetic control.
