Mosquitoes are both vectors of disease and a hindrance to outdoor activities. Since its discovery in 1976, the larvicide Bacillus thuringiensis var. israelensis (Bti) has proven its effectiveness in controlling mosquito populations, with negligible environmental impact. We performed an integrated, 5-year study of the direct and indirect effects of Bacillus thuringiensis var. israelensis (Bti applied as VectoBac® WG) on phytoplankton communities in the Camargue temporary wetlands of the French Mediterranean coast. Mosquito larvae are considered major algae predators, so a significant reduction in mosquito larval density (>80%) in natural wetlands due to Bti treatment could indirectly affect phytoplankton communities. Physical parameters and phytoplankton were sampled in the water of three temporary oligohaline pools between 2006 and 2011 in the following order: T0=1 day before treatment (control), T2=2 days after treatment, T5=5 days after treatment, T11=11 days after treatment. We found no negative effects of Bti treatments on total phytoplankton density and community diversity (Shannon's entropy and Pielou's evenness). However, we observed changes in the density of some taxonomic groups; Diatoms were replaced by drought-resistant algae typical of temporary wetlands. These results suggest that changes in phytoplankton community structure are largely driven by natural environmental factors and by the ecological complexity of these temporary wetlands.

This article is a corrigendum of a former version by Fayolle et al., originally published in Ann. Limnol. - Int. J. Lim. 51: 189–198, 2015. In its original form, the article contained portions of text that were identical to Duguma et al., J. Appl. Ecol. 52: 763–773, 2015, similarities that were not detected by our plagiarism detection software upon initial submission of Fayolle et al.'s manuscript. Based on independent investigations, the Editors of Ann. Limnol. - Int. J. Lim. and J. Appl. Ecol. established that Duguma et al.'s words found in Fayolle et al. were suggested to the latter authors during the review process (without citing any source), so that Fayolle et al. unintentionally reproduced sentences by Duguma et al. in their revised manuscript. After due consideration, authors and Editors concluded that a retractation of Fayolle et al. was not appropriate. The Editors of Ann. Limnol. - Int. J. Lim. have asked Fayolle et al. to prepare a corrigendum by rewriting those parts of the text that are identical to Duguma et al., and referencing the article in J. Appl. Ecol. Where Ann. Limnol. - Int. J. Lim. is concerned, plagiarism check remains a common practice at the time of first submission, but we will now systematically check revised manuscripts as well. Last, we wish to thank the authors of both articles as well as the Editor of J. Appl. Ecol. for helping us sorting out a very difficult situation.
