Does mosquito control by Bti spraying affect the phytoplankton community? A 5-year study in Camargue temporary wetlands (France)
Bacillus thuringiensis var. israelensis (Bti) is the larvicide considered most effective in controlling mosquito populations, with negligible environmental impacts. However, field applications of Bti raise the question of possible effects on food web structure, with potential subsequent proliferations of phytoplankton due to mosquito elimination.
