  1. 1. 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

  2. 2. Host-seeking activity of Ixodes ricinus in relation to the epidemiology of Lyme borreliosis in Sweden

    Author : Hans Mejlon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Borrelia burgdorferi; control; Ixodes ricinus; Lyme borreliosis; seasonality; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; Entomology; entomologi;

    Abstract : This thesis examines seasonal, diel and vertical distribution patterns of activity of host-seeking Ixodes ricinus (L.) ticks at three localities in south-central Sweden. In addition, by examining the prevalence of infection in ticks with Lyme borreliosis (LB) spirochetes, Borrelia burgdorferi s. READ MORE

  3. 3. Ticks - ecology, new hazards, and relevance for public health

    Author : Thérese Janzén; Monica Hammer; Patrik Dinnétz; Mona Petersson; Lars Korslund; Södertörns högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea region; eco-epidemiology; habitat; Ixodes persulcatus; Ixodes ricinus; landscape; risk; urbanization; Environmental Studies; Miljövetenskapliga studier; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Abstract : Ticks and tick-borne diseases are ranking second only to mosquitoes as vectors of pathogens responsible for diseases in both humans and domestic animals. In the countries around the Baltic Sea, two medically important tick species are increasing both in range and abundance, and the public health threat posed by tick-borne diseases in this area is steadily growing.

  4. 4. The Origin of the Genus Flavivirus and the Ecology of Tick-Borne Pathogens

    Author : John H.-O. Pettersson; Thomas Jaenson; Sven Bergström; Kenneth Nilsson; Mikael Thollesson; Per-Eric Lindgren; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Flavivirus; Virus dating; Molecular dating; Biogeography; Ixodes ricinus; Minimum infection rate; TBE; Tick-borne encephalitis virus; Rickettsia helvetica; Anaplasma phagocytophilum; Infection prevalence; RT-PCR; Biology with specialization in Systematics; Biologi med inriktning mot systematik;

    Abstract : The present thesis examines questions related to the temporal origin of the Flavivirus genus and the ecology of tick-borne pathogens. In the first study, we date the origin and divergence time of the Flavivirus genus. It has been argued that the first flaviviruses originated after the last glacial maximum. READ MORE

  5. 5. Plant-Derived Chemicals as Tick Repellents

    Author : Samira Sadek Garboui; Thomas Jaenson; Katinka Pålsson; Raimondas Mozuraitis; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ixodes ricinus; plants; essential oils; tick repellent; Sweden; Biology; Biologi;

    Abstract : Ixodes ricinus is the main vector of Lyme borreliosis and Tick-borne encephalitis in Europe. Repellents provide a practical means of protection against tick bites and can therefore reduce transmission of tick-borne diseases. READ MORE
