  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

  2. 2. Color and wing size: identifying targets of sexual selection in Drosophila melanogaster

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Ellen Pääjärvi Våg; [2024]
    Keywords : Sexual selection; wing interference patterns; Drosophila melanogaster; visual signaling; sexuell selektion; vingmönster; bananfluga; visuell signalering;

    Abstract : This study explores the relationship between wing size, coloration, and reproductivesuccess in Drosophila melanogaster, fruit flies. Sexual selection, a key aspect ofevolutionary biology, often involves visual signaling as a means of displaying geneticinformation. READ MORE

  3. 3. A computational model of metapopulation dynamics and organism-mediated nutrient flow

    University essay from Göteborgs universitet / Institutionen för biologi och miljövetenskap

    Author : Amanda Hansson; [2023-08-07]
    Keywords : computational model; population dynamics; metapopulation dynamics; nutrient flow; simulation; spatially explicit; individual-based;

    Abstract : The aim of this project was to assess, using in-silico experiments, how different life history char-acteristics, such as age at maturity and dispersal ability of individuals, influence the dynamics of a metapopulation. To achieve this, a novel model of a spatially explicit metapopulation, with organ-ism-mediated nutrient flow between fragmented habitat patches, was implemented by means of computer simulations.

  4. 4. Comparison of drone ecology and behavior between Apis mellifera mellifera and the hybrid Buckfast in southwestern Sweden

    University essay from Högskolan i Skövde/Institutionen för biovetenskap

    Author : Finja Schaumann; [2023]
    Keywords : ;

    Abstract : Most research on the biology of the western honey bee (Apis mellifera) focuses on the worker bees, but knowledge about drones is lacking despite their important role in mating with a virgin queen. Available information about their ecology and behavior are mainly based on direct observations in need of intensive experience and knowledge about honey bees. READ MORE

  5. 5. Reproduktionsproblem hos border collie : en enkätstudie riktad till uppfödare av border collie

    University essay from SLU/Dept. of Clinical Sciences

    Author : Johanna Nilsson Johansson; [2023]
    Keywords : hund; reproduktion; östralcykel; dräktighet; valpning; valp;

    Abstract : Målet för denna studie var att undersöka om det finns en underliggande reproduktionsproblematik hos rasen border collie idag som ej är känd. För första gången har tikars förlopp samt uppfödares beslut rapporterats in gällande parning, dräktighet samt valpning. READ MORE
