  2. 21. Plants as Sources of Natural and Effective Acaricides : Against Ixodes ricinus  (Acari: Ixodidae)

    Author : Fawzeia Elmhalli; Giulio Grandi; Richard Wall; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Acaricidal; Ixodes ricinus; Libyan plants; essential oils; Plant-derived acaricides.; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : Ticks and tick-borne diseases are major health hazards worldwide, with increasing numbers of cases of Lyme disease and tick-borne encephalitis reported yearly. Meanwhile, concerns about the environmental impact and safety of chemical acaricides are driving research into alternative control methods, such as plant-based acaricides. READ MORE

  4. 22. Stress Related Emissions of Norway Spruce Plants

    Author : Marie Pettersson; Anna-Karin Borg-Karlson; Torkel Berglund; Åsa Emmer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; volatiles; terpenes; green leaf volatiles; stress response; nepetalactone; SPME; Picea abies; Hylobius abietis; Cinara pillicornis; Chemistry; Kemi;

    Abstract : The interactions between plants and insects are mediated by volatile molecules. Plants respond to stress by biosynthesis of chemical substances which can deter invading insects or pathogens. Some of these substances are volatile and are emitted to the surroundings and may attract or repel insects. READ MORE

  5. 23. Chemical defence in Norway spruce

    Author : Marie Danielsson; Anna-Karin Borg-Karlson; Anders Backlund; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; volatiles; terpenes; green leaf volatiles; stilbenes; stress response; nepetalactone; Picea abies; Hylobius abietis; Cinara pilicornis; Oligonychus ununguis; Heterobasidion annosum; Chemistry; Kemi;

    Abstract : Norway spruce (Picea abies) responds to stress by biosynthesis of chemical substances, which can deter invading insects or pathogens. Some of these substances are volatile and can be emitted to the surroundings while others are accumulated within the tree. READ MORE

  6. 24. Developmentof an immunosensor for enumeration of Nitrobacter

    Author : Björn Sandén; KTH; []
    Keywords : ;

    Abstract : Eutrophication is a result of increasing discharges ofnutrients and is the main cause of the deterioration of theaquatic ecosystems. Major sources of nitrogen in coastal watersare wastewater treatment plants. READ MORE

  7. 25. Chemosensation in Aedes aegypti: from molecular response profiles to host-seeking behaviour

    Author : Anaïs Tallon; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : 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.
