Resumen
Se encontraron especies de mosquitos Aedes selváticos, posibles vectores de arbovirus, criando en huecos de árboles en Sudán
Área de la Ciencia:
- Entomología Médica
- Salud Pública
- Enfermedades Transmitidas por Vectores
Sus antecedentes:
- Las enfermedades transmitidas por Aedes representan una amenaza creciente para la salud pública en Sudán.
- Existe un conocimiento limitado sobre la cría de mosquitos Aedes en hábitats naturales de huecos de árboles.
- Este estudio investiga la fauna de mosquitos Aedes en huecos de árboles dentro del estado de Sennar.
Objetivo del estudio:
- Identificar y cuantificar las especies de mosquitos Aedes que crían en huecos de árboles en diferentes especies de árboles.
- Evaluar el papel potencial de estos sitios de cría en huecos de árboles en la transmisión de arbovirus.
Principales métodos:
- Se realizaron encuestas de larvas en tres sitios de estudio durante la temporada de lluvias.
- Se inspeccionaron 253 huecos de árboles para determinar la presencia y abundancia de larvas de Aedes.
- Se identificaron especies de Aedes utilizando especímenes de larvas recolectadas.
Principales resultados:
- Casi el 40% de los huecos de árboles inspeccionados (99 de 253) resultaron positivos para larvas de Aedes.
- Se identificaron ocho especies de Aedes, siendo Aedes luteocephalus la más prevalente (45,5%).
- Los huecos de árboles de Psidium guajava y Mangifera indica mostraron una mayor diversidad y densidad de especies de Aedes.
Conclusiones:
- La prevalencia de especies de Aedes selváticas, conocidos vectores de arbovirus, es una preocupación importante.
- Estos hallazgos resaltan el potencial de transmisión de arbovirus en reservas naturales.
- La cría de Aedes en huecos de árboles debe integrarse en las estrategias de control de enfermedades arbovirales.

Crop cultivation has a long history in human civilization, with records showing the cultivation of cereal plants beginning at around 8000 BC. This early plant breeding was developed primarily to provide a steady supply of food.

02:40The Tree of Life - Bacteria, Archaea, Eukaryotes
38.4K
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

01:19Survival Tree
423
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

The human bronchi and bronchial tree play a crucial role in the respiratory system, facilitating the exchange of oxygen and carbon dioxide. Let's delve into the intricate structure and functions of these respiratory components.
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...

Although black holes were theoretically postulated in the 1920s, they remained outside the domain of observational astronomy until the 1970s.
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
