It is used as a larvicide all over the world due to its ability to produce a toxic protein that primarily targets the larvae of mosquitoes. In Sweden, Bti has been applied on a large scale in the form of commercially available granular formulation Vecto Bac G (Valent BioScience, USA). The applications have taken place in the lower Dalalven River Area to control mass outbreaks of the floodplain mosquito Aedes sticticus. |
