  1. 16. Botanical Repellents and Pesticides Traditionally Used Against Haematophagous Invertebrates in Lao PDR

    Författare :Chanda Vongsombath; Thomas Jaenson; Raimondas Mozuraitis; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Ethnobotany; fly larvae; Lao PDR; medical entomology; mosquito repellents; myiasis; plant-based insecticides; terrestrial leeches; Haemadipsidae; Systematics and phylogenetics; Systematik och fylogeni; Organism biology; Organismbiologi; Biologi med inriktning mot systematik; Biology with specialization in Systematics;

    Sammanfattning : Haematophagous parasites and disease vectors such as leeches, ticks, mites, lice, bed bugs, mosquitoes, and myiasis-causing fly larvae are common health problems in Lao Peoples Democratic Republic (Lao PDR). A main aim of my field work in Lao PDR in 2006-2010 was to document traditional knowledge among different ethnic groups about plants that people use to repel or to kill blood-feeding invertebrates.

  3. 17. Charting biodiversity : Scuttle flies and other poorly known insects in Sweden

    Författare :Sibylle Häggqvist; Fredrik Ronquist; Jeff Skevinton; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Systematic Zoology; zoologisk systematik och evolutionsforskning;

    Sammanfattning : Biodiversity has fascinated people in all times. We as a species are part of the global ecosystem and our survival depends on many other species around us. Charting biodiversity, however, has proven more difficult than one could imagine. LÄS MER

  4. 18. Fruit and microbial cues in the behavioural ecology and management of Drosophila suzukii

    Författare :Guillermo Rehermann Del Rio; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Investigating the factors that determine the behaviour of new pests is essential for understanding, predicting and managing their impact on natural and agricultural ecosystems. The spotted wing drosophila (SWD), Drosophila suzukii (Matsumura; Diptera: Drosophilidae), is a worldwide spreading polyphagous pest of soft fruit and berries. LÄS MER

  5. 19. Induced responses in willow determine feeding success of a gall-forming insect

    Författare :Solveig Höglund; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : In the willow Salix viminalis L. (Salicaceae), growth and defence are key responses determining feeding success of the gall midge Dasineura marginemtorquens Bremi (Diptera: Cecidomyiidae). The interaction includes induced growth (gall formation), and induced defence (hypersensitive response, HR). LÄS MER

  7. 20. Mosquitoes as a Part of Wetland Biodiversity

    Författare :Martina Schäfer; Jacob Höglund; Jan Lundström; Darold Batzer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; diversity patterns; species assemblages; functional groups; constructed wetlands; dytiscids; Ekologi; Terrestrial; freshwater and marine ecology; Terrestisk; limnisk och marin ekologi;

    Sammanfattning : Wetlands contain both aquatic and terrestrial environments which generates high biodiversity. However, they are commonly associated with mosquitoes (Diptera: Culicidae), and mosquitoes are usually regarded as negative by humans because they can cause nuisance and transmit diseases. LÄS MER
