| Abstract | We describe how pesticides used for mosquito control alter communities in mosquito breeding sites, and how these alterations affect larval populations of mosquitoes. Lethal and sublethal toxic effects modify biological interactions through density- and trait-mediated changes. Density-mediated effects due to pesticide treatment can lead to indirect positive effects on the target species. For example, recolonization of pests can be amplified due to disturbances of antagonistic species. Trait-mediated effects can result in lethal effects of originally sublethal exposure when the pesticide is combined with additional stress. Such lethal effects can result from changes of behavior or sensitivity. Also the immune capacity and resistance of individuals to parasitic infection could be decreased. Furthermore, pesticide treatment can act independently of toxic effects. For example, habitat and oviposition site selection can be influenced. These examples highlight the diversity of processes to be considered when determining the overall consequences of pesticide treatment. We show that a better understanding of these processes is needed to predict effects of pesticides on population dynamics. Such knowledge would have direct benefits in designing mosquito control strategies. |
