Vector borne disease risk is predominantly limited by the presence, abundance and dispersal of their respective vector. These vector species are spreading quickly due to growing (inter)national trade and travel, climate change and land use change. Insight in vector population dynamics is therefore key to disease control.
Quality and availability of larval habitats are among the most important drivers of mosquito population dynamics and structure. These factors are limited by habitat preferences, which vary across species. Insight in the dynamics and productivity of these habitats may therefore be used to model and predict adult abundance and inform management to limit disease risk. However, most current literature focuses on single stressors. There is therefore a lack of information on interactions effects, although in recent years, there is more attention for this. To provide a basis for modelling mosquito (vector) population dynamics via experimental identification of tipping points, this project will determine the main drivers of population parameters for Culex pipiens (Diptera: Culicidae), the common house mosquito in a mesocosm set-up. For this, the effects of i) abiotic (human) pressures, such as climate variables, nutrient availability and presence of pesticides and ii) biotic interactions, such as predation, viral load, density dependence and interspecific competition will be investigated.
