  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. 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.

    Keywords : Insecticide resistance; gut microbiota; insect pest; host plant preference; sustainable agriculture;

    Abstract : To counteract pesticide resistance development, it is crucial to understand why and when it evolves. Additionally, to inform the farmers about this term and provide advices on efficient pest management strategies to prevent pesticide resistance. READ MORE

  6. 5. Påverkan av jordbearbetning och pesticider på abundans och födoval hos jordlöpare

    University essay from SLU/Dept. of Ecology

    Author : Ellen Dahlgren; [2021]
    Keywords : jordlöpare; ogräsfröpredation; bladluspredation; alternativ föda; insekticider; herbicider; jordbearbetning;

    Abstract : Syftet med denna uppsats är att undersöka om jordlöpares predationsspecialisering (d’) och aktivitetsdensitet (förekomst) påverkas av jordbearbetning, insekticid- och herbicidanvändning. Jordlöpare har samlats in från höstsådda fält i fyra olika länder i Europa och utifrån deras maginnehåll har ett predationsspecialiseringsindex (d’) för ogräsfrön, bladlöss (Aphidoidea), daggmaskar (Lumbricidae) och hoppstjärtar (Collembola) beräknats.
