  1. 1. Pheromone-based mating disruption to control Spodoptera frugiperda in Tanzania: Possibilites and Constraints for smallholders

    University essay from SLU/Dept. of Biosystems and Technology (from 130101)

    Author : Thomas O'Malley; [2024]
    Keywords : pheromone; mating disruption; fall armyworm; Tanzania; smallholder; Spodeptera frugiperda; integrated pest; management;

    Abstract : Despite a growing interest in the use of pheromones as a more sustainable form of pest control, their use remains unstudied in the smallholder context. This paper is one of the first to study their use by small scale Tanzanian maize farmers to control the invasive pest Spodoptera frugiperda (known as fall armyworm). READ MORE

  3. 2. Predicting Chemical-Gene Interactions

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Ali Chishti; [2023-08-04]
    Keywords : Pesticides; Small streams; Prediction modelling; Chemical-protein-gene interactions; Aquatic organisms;

    Abstract : Pesticide use in agriculture has become a growing concern as it can have detrimental effects on the environment. The excessive use of these chemicals often leads to them seeping into nearby water bodies, causing harm to aquatic organisms. READ MORE

  4. 3. ASSESSING MICROBIAL COMMUNITY RESPONSES IN A CHEMICALLY STRESSED FRESHWATER ECOSYSTEM USING ENVIRONMENTAL DNA

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Nicolai Laufer; [2023-06-21]
    Keywords : ;

    Abstract : Microbial communities represent the fundamental cornerstones of riverine ecosystems because they are involved in numerous processes which mediate ecosystem services. However, riverine ecosystems are currently massively altered by a variety of anthropogenic activities which includes changes in landuse and chemical pollution. READ MORE

  5. 4. Modelling Micropollutant Removal Through Ozonation in Wastewater

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maximiliano Andrés Oportus Foster; [2023]
    Keywords : Micropollutants; water reuse; wastewater treatment models; ozonation; computer modeling; water and environmental engineering; Technology and Engineering;

    Abstract : Proper management of water resources is a key to climate change adaptation and resilience in modern societies. Adequate treatment of wastewater is essential for ensuring the sustainability of the water cycle and the health of the environment and the ecosystems that inhabit it. READ MORE

  6. 5. Ecological risk assessment of pesticide use in rice farming in the Mekong Delta , Vietnam

    University essay from Stockholms universitet/Institutionen för naturgeografi

    Author : Bubaraye Ohiosimuan Dirikumo; [2023]
    Keywords : Pesticides; Ecological Risk Assessment ERA ; rice farming; Mekong Delta; PRIMET Model; Exposure Toxicity Ratio ETR ; species sensitivity distribution SSD ; predicted environmental concentrations PECs ;

    Abstract : Pesticide use in rice farming is a common practice in the Mekong Delta and poses ecological risks to aquatic organisms, the environment, and human health. This study focused on the ecological risk assessment of pesticide use in rice farming using the PRIMET model as a decision support tool to evaluate the risks of pesticide exposure, ecotoxicity, and risk characterization, as well as employing the species sensitivity distribution (SSD) assessment model to calculate the potentially affected fraction (PAF) of species based on the computed predicted environmental concentrations (PECs) from PRIMET.
