Other contributing epidemiological factors have either maintained or even enhanced transmission potential in certain areas including various factors that contribute to malaria mosquito vector distribution, vector competency and capacity for transmission,

What Is a Vector in Biology? A Detailed Explanation

VigiLab’s research focuses on mosquito vector biology, infection and immunity, parasite-vector interactions. A major part of our work is the generation and evaluation of transgenic Anopheles mosquitoes that express Plasmodium-targeting effectors designed to block malaria transmission. Malaria is a serious, potentially life-threatening disease caused by Plasmodium parasites. Posing a significant global health challenge, it leads to hundreds of thousands of deaths annually, primarily in tropical regions. This illness is preventable and curable, yet it continues to affect millions worldwide. The Mosquito’s Role The Anopheles mosquito serves as the sole India has committed to eliminate malaria by 2030. The national framework for malaria elimination released by the Government of India plans to achieve this goal through strategic planning in a phased manner. Since vector control is a major component of disease management and vector elimination, it requires a thorough understanding of the biology and

A review discusses how molecular and genetic tools provide insights into the biology of disease transmission by arthropod vectors. Background Malaria remains one of the most significant global health challenges, particularly in tropical and subtropical regions. Despite ongoing control efforts, malaria transmission persists due to complex biological, environmental, and socio-economic factors. Traditional malaria models have primarily focused on vector-borne transmission, overlooking PDF | On Jul 24, 2013, Wannapa Suwonkerd and others published Vector Biology and Malaria Transmission in Southeast Asia | Find, read and cite all the research you need on ResearchGate

Anopheles mosquitoes present a major public health challenge in sub-Saharan Africa; notably, as vectors of malaria that kill over half a million people annually. In parts of the east and southern Africa region, one species in the Funestus group, Anopheles funestus, has established itself as an exceptionally dominant vector in some areas, it is responsible for more The discussion extends to cover key medically important vectors, including mosquitoes, ticks, flies, and fleas, highlighting their roles in disease transmission. Further, vector-borne diseases of high significance are explained in detail from a public health perspective, with the historical perspective of vectors and their

This blood-feeding behavior is the direct link to spreading the malaria parasite. The female mosquito’s need for a blood meal is the engine of malaria transmission, making her a target for control efforts. Species like Anopheles gambiae in Africa and Anopheles darlingi in South America are among the most efficient vectors known.

How Malaria Spreads Malaria transmission occurs when an infected female Anopheles mosquito bites a person. These mosquitoes act as vectors, carrying the parasite from an infected individual to an uninfected one. The cycle begins when a mosquito feeds on a person with malaria, ingesting the Plasmodium parasites present in their blood. Interrupting Transmission Interrupting malaria transmission relies on a multi-pronged approach targeting different stages of the parasite’s lifecycle and the mosquito vector. Vector control methods are important, aiming to reduce mosquito populations or Understand what a vector means in biology. Discover its dual significance as both a biological carrier and a crucial molecular tool.

We argue that future vector control strategies will need to be rooted in basic biology research in insect ecology, behaviour and vector–pathogen–microbiome interactions.

RATIONALE Insecticide-based interventions, namely LLINs and IRS, are currently the core vector control interventions for malaria prevention.

This unique combination of knowledge and excellent facilities enables the study of various aspects of mosquito biology and malaria transmission. The position is embedded within two complementary research teams: the vector biology team led by Dr. Felix Hol and the malaria epidemiology team led by Prof. Teun Bousema. Background Increasing unplanned urbanization in tropical Africa may create new niches for malaria vectors, raising transmission risk, yet control efforts focus on rural ecosystems. Understanding mosquito diversity, ecology and biting behaviour in urban areas is crucial for effective control. This study assessed Anopheles diversity, abundance, behaviour, and Anopheles arabiensis is a malaria carrying mosquito whose reach and adaptability place it at the center of international health efforts. This species is capable of sustaining transmission in diverse ecological zones. This article reexamines the dangers posed by arabiensis and explains why it remains a pressing global health concern.

Vector Biology and Malaria Transmission The Transmission and Vector Biology Unit within the Malaria Research Program conducts research on malaria vectors and parasite transmission using a combination of field, laboratory, and computational approaches, with the overall goal of improving the effectiveness of interventions to prevent malaria. Ongoing projects include

Vector control Vector control is a highly effective way to reduce malaria transmission and is a vital component of malaria control and elimination strategies. WHO currently recommends deployment of either insecticide-treated nets (ITNs) or indoor residual spraying (IRS) for malaria vector control in most areas at risk of malaria. Anopheles stephensi is a highly competent urban malaria vector species, endemic in South Asia and the Persian Gulf, which has colonised eight countries in sub-Saharan Africa (SSA) since 2013 and is now spreading uncontrollably. In urban areas of Africa, where malaria transmission has previously been low or non-existent, the invasion of An. stephensi represents Malaria is a serious disease spread by mosquitoes that bite during the night in many parts of the world. This article rephrases the idea of what causes malaria mosquito bites and presents practical steps to prevent them. By exploring the biology of the vector and the means of protection, readers can understand how to reduce risk in daily life and while traveling.

Among six dominant mosquito vector species involved in malaria transmission in India, Anopheles minimus is a major species in northeast India and held responsible for focal disease outbreaks characterized by high-rise of Plasmodium falciparum infections and attributable death cases. It has been now genetically characterized that among the three-member species Vectors are agents that transmit pathogens between hosts. Inanimate vectors include food, water, and contaminated objects, while China has set a goal to eliminate all malaria in the country by 2020, but it is unclear if current understanding of malaria vectors and transmission is sufficient to achieve this objective. Anopheles sinensis is the most widespread malaria vector specie in China, which is also responsible for vivax malaria outbreak in central China.

Malaria is an infectious disease caused by Plasmodium parasites, transmitted by Anopheles sinensis, Anopheles lesteri, Anopheles minimus, and Anopheles dirus in China. In 2021, the disease was eliminated in China after more than 70 years of efforts implementing an integrated mosquito management strategy. This strategy comprised indoor residual spray, insecticide Background Malaria transmission in Africa is facilitated by multiple species of Anopheles mosquitoes. These vectors have different behaviors and vectorial capacities and are affected differently by vector control interventions, such as insecticide-treated nets and indoor residual spraying. This review aimed to assess changes in the contribution of different vector

Vector biology will play a major role in the battle against malaria. Improved vector surveillance networks will allow most countries, particularly those in Africa, to mount effective control efforts and to predict outbreaks of disease. Researchers will be able to conduct epidemiologic surveys and track drug resistance simply by analyzing mosquito populations. Simple techniques will be Advances on the Gametocyte Biology, Host Immunity and Vector Stages to interrupt the Transmission of Malaria Stringent malaria control efforts have reduced the global malaria burden in the past decade.
