  1. 1. The effects of a new gall midge in the Panamanian fig/fig wasp mutualism

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Roberta Hedberg; [2022]
    Keywords : ;

    Abstract : The mutualism between the fig tree and the fig wasp pollinator is an important keystone interaction for tropical forests. However, many antagonistic and parasitic species take advantage of the fig/fig wasp mutualism. One such parasite is the gall midge that develops inside fig syconia. READ MORE

  3. 2. Host plant selection in closely related butterfly species due to reproductive interference: Modelling a tritrophic system

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Alexandros Bantounas; [2021]
    Keywords : reproductive interference; habitat selection; modelling; phytophagous insects;

    Abstract : Host plant selection is an important process during the life cycle of lepidopterans, providing ovipositing sites for adults and food resources for the larvae. The processes behind host plant selection have been extensively studied, especially in closely related species in the context of niche separation. READ MORE

  4. 3. Bönsmyg i åkerböna : hur påverkas avkastning och skördekvalitet?

    University essay from SLU/Dept. of Ecology

    Author : Emma Ryding; [2020]
    Keywords : bönsmyg; Bruchus rufimanus; åkerböna; Vicia faba; avkastning; kvalitet;

    Abstract : Bönsmygen (Bruchus rufimanus) uppmärksammades som skadegörare i åkerbönor (Vicia faba) i Sverige 2008 och sedan dess har förekomsten och spridningen av den ökat snabbt. Det saknas kännedom om bönsmygens betydelse och hur den ska bekämpas vilket gör den till ett potentiellt hot i det svenska jordbruket. READ MORE

  5. 4. Are tritrophic interactions shaped by plant genotype? A field experiment.

    University essay from Institutionen för ekologi, miljö och geovetenskap

    Author : Ylva Nordström; [2013]
    Keywords : Tritrophic interactions; plant genotype; aggregative behaviour; Galerucella tenella; Asecodes parviclava;

    Abstract : In recent years it has become apparent that when studying plant-herbivore interactions, it is important to also consider the multitrophic context, i.e. to what extent generalist and specialist enemies act as bodyguards for the plant. READ MORE

  6. 5. Effects of leaf beetle herbivory on pollination success and fruit development in woodland strawberry Fragaria vesca

    University essay from SLU/Dept. of Ecology

    Author : Lisa Malm; [2013]
    Keywords : herbivory; pollination success; pollinator reference; fruit development; fruit yield; leaf beetles; Galerucella tenella; Galerucella sagittariae; Fragaria vesca;

    Abstract : Cultivating well-developed and marketable garden strawberries (Fragria x ananassa) and woodland strawberries (Fragaria vesca) depends on successful pollination by insects. Organic garden strawberry plantations harbour higher pollinator densities and have been shown to produce bigger and better developed fruits than conventional farms. READ MORE
