1. 11. 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

3. 12. Ecology and control of Anopheles mosquitoes and human malaria in Guinea Bissau, West Africa

   Författare :Katinka Pålsson; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; Anopheles; Bed nets; Epidemiology; Malaria control; Natural mosquito repellents; Plasmodium; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi; Entomology; entomologi;

   Sammanfattning : This thesis analyses the relationship between risk of exposure to infective Anophelesmosquitoes and different environmental factors, in particular house construction, presence ofdomestic animals and house location, in coastal Guinea Bissau, West Africa. The potentialeffect of permethrin-impregnated bed nets on mosquito abundance in bed rooms, and on thePlasmodium parasite prevalence in children was also analysed. LÄS MER

4. 13. 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

5. 14. Phagostimulatory dynamics of adenine nucleotides in mosquitoes : advancing a taste-based delivery method for vector control agents

   Författare :Matthew Lukenge; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : The mosquitoes Aedes aegypti and Anopheles gambiae are vectors of major medical importance, incriminated in over half a million lives lost annually. While there has been significant focus on understanding the olfaction mechanisms underlying host-seeking in mosquitoes for the development of odour-based control tools, little is known about the mechanisms underlying gustation in blood feeding, the ultimate behaviour in the change of events leading up to disease transmission.

7. 15. Exploration of bacteria associated with Anopheles mosquitoes around the world : For the prevention of transmission of malaria

   Författare :Louise K. J. Nilsson; Olle Terenius; Staffan Svärd; Sebastian Håkansson; Michael Strand; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; microbiota; microbiome; vector-borne disease; 16S rRNA gene; amplicon sequencing; Biologi med inriktning mot mikrobiologi; Biology with specialization in Microbiology;

   Sammanfattning : Every year, hundreds of thousands of people die from malaria. Malaria is a disease caused by parasites, which are spread by female vector mosquitoes of the genus Anopheles. Current control measures against malaria are based on drugs against the parasites and vector control using insecticides. LÄS MER
