Negative density-dependent dispersal in tsetse flies : a risk for control campaigns ? /De Meeûs, Thierry /Ravel, Sophie /Solano, Philippe Bouyer, J. Tsetse flies are vectors of parasites that cause diseases responsible for significant economic losses and health issues in sub-Saharan Africa, including sleeping sickness in humans and nagana in domestic animals. Efficient vector-control campaigns require good knowledge of the demographic parameters of the targeted populations. In the last decade, population genetics emerged as a convenient way to measure population densities and dispersal in tsetse flies. Here, by revealing a strong negative density-dependent dispersal in two dimensions, we suggest that control campaigns might unleash dispersal from untreated areas. If confirmed by direct measurement of dispersal before and after control campaigns, area-wide and/or sequential treatments of neighboring sites will be necessary to prevent this issue. 2019 text https://www.documentation.ird.fr/hor/fdi:010076518 fdi:010076518 De Meeûs Thierry, Ravel Sophie, Solano Philippe, Bouyer J..
