  2. 1. Selective inhibition of acetylcholinesterase 1 from disease-transmitting mosquitoes : design and development of new insecticides for vector control

    Author : Cecilia Engdahl; Anna Linusson; Fredrik Ekström; Zoran Radić; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; acetylcholinesterase; non-covalent inhibitor; vector control; insecticide; mosquito; vector-borne disease; high throughput screening; rational design; biokemi; Biochemistry; datorlingvistik; computational linguistics;

    Abstract : Acetylcholinesterase (AChE) is an essential enzyme with an evolutionary conserved function: to terminate nerve signaling by rapid hydrolysis of the neurotransmitter acetylcholine. AChE is an important target for insecticides. READ MORE

  4. 2. Exploiting plant defenses to protect conifer seedlings against pine weevils

    Author : Yayuan Chen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : Sweden is one of the top five countries having large planted forest areas, and here the forests are maintained by clear-cut regime, which also promotes the pine weevil (Hylobius abietis), a major threat to Swedish planted coniferous regeneration. Given interest in developing sustainable forest management practices, efficient non-insecticide alternatives are highly demanded to tackle the pine weevil problem. READ MORE

  5. 3. Biological control of diamondback moth : the roles of predators, parasitoids and insecticides

    Author : Freddy Miranda; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Abstract : The diamondback moth Plutella xylostella L. (Lepidoptera: Plutellidae) is a serious pest of economically important crucifer crops such as cabbage. The moth has developed resistance to all tested insecticides and further studies on the potential role of factors affecting P. xylostella survival, including natural enemies, are urgently needed.

  6. 4. Optimization of intermittent preventive therapy for malaria during pregnancy : effectiveness of dihydroartemisinin-piperaquine versus sulfadoxine-pyrimethamine

    Author : Eulambius Mathias Mlugu; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Malaria is a Tropical disease caused by different parasites species of genius Plasmodium. Because of pregnancy associated lowered immunity, women who are pregnant are at higher risk to malaria infection than non-pregnant women. READ MORE

  7. 5. Understanding the adaptive capacity of the bumblebee Bombus terrestris across native and novel environments

    Author : Cecilia Hjort; Biodiversitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bumblebees; Bombus terrestris; Pollination; Introgression; Single nucleotide polymorphisms; Whole Genome Sequencing; Landscape simplification; Gene flow; Morphology; Environmental variation; Invasion; Local adaptation; Island;

    Abstract : Anthropogenic stressors such as agricultural intensification, climate change, andincreased densities of non-native managed bees used for crop pollination arecontributing to bee declines. Understanding how and why bees have responded topast environmental changes is crucial for predicting future ones and enablingmitigation to maintain the functioning of both natural and agricultural ecosystems.
