Mosquito

Sustainable mosquito control

Global change and pesticide resistance are challenging conventional mosquito control.  We integrate the application of larvicides and ecological stressors towards improved, sustainable control strategies.

Conventional mosquito control is based on the application of pesticdes against the larval or the adult stage. However, they can impair numerous non-target species and caused the worldwide spreading of resistant mosquitoes.

Integrated Mosquito ControlWe develop integrated control approaches considering how ecological mechansims can alter the effects of such pesticides. Currently, we focus on the introduction of  competitors combined with the application of the biological larvicide B.t.i.

  • While B.t.i. causes a strong but short-lasting decrease of mosquito larvae, competing makrozooplankton takes time to establish but can then supress the larval development in the long run [1,2].

  • The combination of both effects can efficiently reduce both larval populations and the frequency of required applications.

This approach is constantly refined and its applicability tested under field conditions in Germany and Kenya.
