Analyse du rôle des prédateurs aquatiques (odonate, Notonectes) dans la régulation naturelle des larves de moustique.

Abstract

Mosquito-borne diseases pose a significant global public health problem due to their role in transmitting diseases such as malaria, dengue fever, and chikungunya. Given the limitations of chemical insecticides, particularly their environmental impact and mosquito resistance, biological control offers a sustainable alternative. The natural regulation of mosquito populations by large predators is a key component of integrated mosquito control. Among these predators, notonecta (water bugs), dragonflies, and dracaena larvae play a vital role in stagnant aquatic environments due to their strong predatory capacity. Their effectiveness depends on several factors, including their hunting strategies, life cycle, environmental conditions, their role in the natural regulation of mosquito larvae, and their contribution to maintaining the balance of aquatic ecosystems. Predators are a promising biological control tool and are essential in integrated mosquito management programs to reduce the use of chemical pesticides and conserve biodiversity.
