  2. 1. The Evolution of Sexually Homologous Ornaments : Selection via Male Mate Choice Coinciding with Male-Male Competition in a Neotropical Mosquito

    Author : Sandra South; Göran Arnqvist; Russell Bonduriansky; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; sexual selection; Sabethes cyaneus; Diptera; Culicidae; mosquito; mutual ornamentation; sexual selection; mutual mate choice; male mate choice; female ornament; ecology; animal behaviour; Ethology and behavioural ecology; Etologi och beteendeekologi; Animal Ecology; Zooekologi;

    Abstract : The evolution of elaborate male ornaments via sexual selection is well-understood while the selective pressures acting on female ornaments remains unresolved. Female ornaments in species with strong sexual selection on the male homologue of the ornament were originally thought to result from an intersexual genetic correlation. READ MORE

  4. 2. An epidemiological and virological study on mosquito-borne flavivirus transmission : The role of urban livestock keeping and the risk for mosquito-borne zoonotic diseases in humans in Hanoi city, Vietnam

    Author : Thang Nguyen-Tien; Johanna Lindahl; Åke Lundkvist; Richard Paul; Uppsala universitet; []
    Keywords : urban flavivirus; mosquito-borne diseases; livestock keeping; urban Vietnam; Southeast Asia.; Medicinsk vetenskap; Medical Science;

    Abstract : Mosquito-borne diseases (MBDs), which are transmitted by the bite of mosquitoes to humans, are causing high morbidity and mortality worldwide and are emerging in many tropical cities. Urban livestock keeping is still growing in cities around the world, which can itself contribute to increasing the mosquito populations. READ MORE

  5. 3. Selective inhibition of acetylcholinesterase 1 from disease-transmitting mosquitoes : design and development of new insecticides for vector control

    Author : Cecilia Engdahl; Anna Linusson; Fredrik Ekström; Zoran Radić; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acetylcholinesterase; non-covalent inhibitor; vector control; insecticide; mosquito; vector-borne disease; high throughput screening; rational design; biokemi; Biochemistry; datorlingvistik; computational linguistics;

    Abstract : Acetylcholinesterase (AChE) is an essential enzyme with an evolutionary conserved function: to terminate nerve signaling by rapid hydrolysis of the neurotransmitter acetylcholine. AChE is an important target for insecticides. READ MORE

  6. 4. Towards Mosquitocides for Prevention of Vector-Borne Infectious Diseases : discovery and Development of Acetylcholinesterase 1 Inhibitors

    Author : Sofie Knutsson; Anna Linusson; Fredrik Almqvist; Andreas Larsson; Ulf Nilsson; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mosquito; vector-borne diseases; vector control; insecticide; acetylcholinesterase; medicinal chemistry; high-throughput screening; organic synthesis; homology modeling; structure activity relationship; structure selectivity relationship; datorlingvistik; computational linguistics; organisk kemi; Organic Chemistry;

    Abstract : Diseases such as malaria and dengue impose great economic burdens and are a serious threat to public health, with young children being among the worst affected. These diseases are transmitted by mosquitoes, also called disease vectors, which are able to transmit both parasitic and viral infections. READ MORE

  7. 5. Identification of bacteria associated with malaria mosquitoes - Their characterisation and potential use

    Author : Jenny Lindh; Ingrid Faye; Marcelo Jacobs-Lorena; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Malaria; mosquito; Anopheles; bacteria; paratransgenics; semiochemicals; Molecular biology; Molekylärbiologi; molekylärgenetik; Molecular Genetics;

    Abstract : The use of transformed bacteria to stop or kill disease-causing agents in the gut of vector insects is called paratransgenics. Two of the major steps in creating a paratransgenic Anopheles mosquito, unable to spread the Plasmodium parasites that cause malaria, are to find a bacterium suitable for the purpose and a way to introduce the transformed bacterium into mosquitoes in the field.
