Host-seeking behaviour in the malaria vector Anopheles Gambiae
In sub-Saharan Africa, 90% of malaria cases are the result of transmission by the Anopheles gambiae species complex, causing 600,000 deaths annually. Increasingly, An. gambiae demonstrate behavioural and physiological resistance to control interventions and this, coupled with inadequate sampling …

The potential for environmental management to contribute to malaria vector control in western Niger
… management techniques to contribute to malaria vector control in Niger, with a case study on Banizoumbou village in western Niger. Numerical modeling was used to simulate habitat modifications in the form of leveling a topographic depression, ploughing the land surface to enhance …

Immunological Crosstalk between Human Transforming Growth Factor-β1 and the Malaria Vector Anopheles stephensi
… in the last twenty years has made control of malaria more difficult. One novel strategy to better control malaria is the development and release of transgenic mosquitoes whose enhanced immunity prevents transmission of the parasite to the mammalian host. One candidate effector gene is …

The Role of PGRP Proteins in Innate Immunity Pathways in the Malaria Vector Anopheles gambiae
… of the mosquito Anopheles gambiae, the main vector of human malaria in sub-Saharan Africa. The PGRP gene family consists of seven genes with ten PGRP domains. We have shown that from all PGRP genes only PGRPLC has a role in the resistance to bacterial infections of both Gram types. In our …

Landing behaviour of the host seeking malaria vector anopheles coluzzii in response to host associated cues
… Anopheles transmit the parasites responsible for malaria, one of the most serious vector-borne diseases, which affects one-fifth of the world population. Current malaria prevention relies heavily on vector control interventions, which are most effective and sustainable when based on mosquito …

Characterization of the expression patterns of the retrogene-parental gene pairs in the African malaria vector Anopheles coluzzii
Retrogenes are a group of functional genes produced by gene retroduplication events during evolution. It has been observed that many retrogenes have formed since the evolutionary divergence of Anopheles mosquitoes from the Aedes lineage as a result of developing heteromorphic sex chromosomes. It …

The reproductive health effects of along term DDT exposure on malaria vector control workers in Northern Province, South Africa
… including South Africa for the control of malaria vectors, have been shown to be endocrine disruptors in vitro and in vivo. The study hypothesis was that male vector control workers highly exposed to DDT in the past should demonstrate clinically significant exposure-related anti-androgenic …

The hydrology of malaria : field observations and mechanistic modeling of the malaria transmission response to environmental climatic variability
A coupled HYDrology, Entomology and MAlaria Transmission Simulator (HYDREMATS) has been developed. The model simulates the hydrological and climatological determinants of malaria transmission mechanistically and at high spatialand temporal resolution, and is valid for semi-arid, desert fringe …

Blood host preferences and competitive inter-species dynamics within an African malaria vector species complex inferred from signs of animal activity around aquatic larval habitats distributed across a gradient of fully domesticated to fully pristine ecosystems in southern Tanzania
The effectiveness of current first-choice vector control interventions on the semi-zoophagic vector Anopheles arabiensis are limited, among other things, by insecticide resistance and their ability to acquire non-human bloodmeals. Across much of southern Tanzania, in areas where humans and cattle …

Assessment of impacts of indoor residual house spraying (IRHS) on the diversity, abundance and distribution of human malaria vectots in Chongwe District, Zambia
Dominant human malaria vectors in Chongwe district, Zambia, were identified and impacts of indoor Residual House Spraying (IRHS) on their diversity, abundance and distribution assessed. A case-control type of study design was used in which Chishiko village in the district was the case in point, …

Evaluation of Novel Carbamate Insecticides for Neurotoxicity to Non-Target Species
Malaria (vector: Anopheles gambiae) is a major infectious disease that kills about 1 million people each year. For the improvement of its treatment and vector control during the past decades, several issues such as high medicine cost, insecticide resistance, and lack of an effective vaccine have …

Molecular, Biochemical, and Toxicological Evaluation of Anticholinesterases for control of the Malaria Mosquito, Anopheles gambiae
… treated nets (ITNs), the first line of malaria vector control. Widespread resistance development to pyrethroids undermines current control efforts, and hence an urgent need for alternative chemistries. I report the evaluation of pharmacological differences between insect and vertebrate …

Are Post-Transcriptional RNA Modification Events in the Glutamate-Gated and GABA-Gated Chloride Channels of Anopheles minimus and Anopheles dirus associated with Ivermectin Insensitivity?
Mosquito-borne diseases, most notably malaria, have been a constant public health challenge in many regions around the world claiming the lives of hundreds of thousands every year. Vector control strategies such as insecticide use were initially effective in reducing malaria transmission. However, …

Using Molecular Diagnostics Based On Internal Transcribed Spacer 2 Sequence To Study Geographical Distribution of Holarctic Malaria Mosquitoes
Diseases like malaria claim the lives of millions of people every year. This deadly disease can result in considerable morbidity, which presently affects countries in Africa, Eurasia, and South America. Anopheline mosquitoes transmit this disease. Studies look at the identification first of the …

The effect of removing tariffs and domestic taxes on insecticide treated nets (ITNs), netting materials and insecticides in Zimbabwe
… has already proved to be a cost effective way of malaria vector control. The important emphasis now should therefore be on how to increase the accessibility and utilization of the mosquito nets through devising viable financing and promotional mechanisms that are sustainable and equitable in the …

Application of Chromosome Mapping to Understanding Evolutionary History of Anopheles Species
Malaria is the main cause of approximately one million deaths every year that mostly affect children in south of Sub-Saharan Africa. The Anopheles gambiae complex consists of seven morphologically indistinguishable sibling species. However, their behavior, ecological adaptations, vectorial …

Comparative genomics of chromosomal rearrangements in malaria mosquitoes
… inversions, a physical map for an Asian malaria vector, Anopheles stephensi, was created and compared with the maps of the major African malaria vectors A. gambiae and A. funestus No interchromosomal transposition was observed between A. gambiae and A. stephensi. Several cases of …
