The Role of Hexapods in Ecosystem Stability and Transmitted Diseases: A Review Article

Abstract

Hexapods are a diverse group of insects and their related arthropods that play a vital role in shaping and maintaining terrestrial ecosystems. Their ecological functions include pollination, decomposition, soil aeration, and natural pest control, all of which contribute significantly to ecosystem stability. Some species among hexapods are the most efficient vectors of different pathogenic diseases, such as malaria, dengue fever, Lyme disease, and Chagas. Thus, these organisms place themselves in a rather complicated interface of biodiversity conservation and disease epidemiology. Changes in the environment due to climate change, habitat destruction or urbanization would influence the ecological roles played by hexapods in the transmission of vector-borne diseases. This double use highlights their essential ecological roles while also exploring them as agents of disease transmission. Recent studies on both negative and positive impacts will therefore be reviewed here to allow an understanding of how hexapods impact ecosystem functioning and human health. This duality is also very important for integrated strategies that provide support towards achieving ecological sustainability while reducing health risks amid global ecological changes. It seeks to give an even and broad view of the ecological helps by hexapods and the public health dangers linked with insect-borne sicknesses. Such a grasp is key for biodiversity care, sustainable growth, and health readiness in a fast-changing world.
