  1. 1. Climate Change, Dengue and Aedes Mosquitoes : Past Trends and Future Scenarios

    Sammanfattning : Background Climate change, global travel and trade have facilitated the spread of Aedes mosquitoes and have consequently enabled the diseases they transmit (dengue fever, Chikungunya, Zika and yellow fever) to emerge and re-emerge in uninfected areas. Large dengue outbreaks occurred in Athens in 1927 and in Portuguese island, Madeira in 2012, but there are almost no recent reports of Aedes aegypti, the principal vector, in Europe. LÄS MER

  3. 2. Decoding the language of transmission among vector-pathogen-host

    Författare :Melika Hajkazemian; S. Noushin Emami; Richard Hopkins; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Vector-borne disease; Malaria; Anopheles; Plasmodium falciparum; Zika; Aedes; Vector control strategy; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Vector-borne diseases account for over 17 percent of all infectious diseases and lead to more than 700,000 mortalities annually. Importantly, there is a complex interaction between infectious organisms and their host. LÄS MER

  4. 3. Chemosensation in Aedes aegypti: from molecular response profiles to host-seeking behaviour

    Författare :Anaïs Tallon; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The female mosquito Aedes aegypti is the primary urban vector of various highly infectious neglected tropical diseases. Disease transmission relies heavily on odourmediated behaviours, including e.g., sugar- and host-seeking, which are crucial during the mosquito life cycle and has dire impacts on vectorial capacity.

  5. 4. Oviposition site selection in mosquitoes : the role of conspecific larvae, heterospecific larvae and microbes

    Författare :Zaid Khan; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In mosquitoes, the evaluation and selection of oviposition sites is critical for the growth, development and survival of the offspring. Gravid mosquitoes rely primarily on olfactory cues emanating from breeding water containing, e.g., intra- and interspecific aquatic stages, as well as bacteria for this purpose. LÄS MER

  7. 5. Odour-mediated host preference in mosquitoes: the role of the maxillary palps in host recognition

    Författare :Shahid Majeed; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The mechanisms underlying host preference in mosquitoes are ultimately a result of optimal foraging on currently available hosts and historical patterns of host availability. The proximate mechanisms are regulated by available host cues and the nature of the mosquitoes’ responses to these cues. LÄS MER
