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. specialized BURKINA FASO CAMEROUN GHANA OUGANDA TANZANIE KENYA AFRIQUE SUBSAHARIENNE 052 080 35 8 615-621 2019 1471-4922 https://www.documentation.ird.fr/hor/fdi:010076518 10.1016/j.pt.2019.05.007 1471-4922 [F B010076518] https://www.documentation.ird.fr/hor/fdi:010076518 https://www.documentation.ird.fr/intranet/publi/2019/08/010076518.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2019-09-19 2025-02-24 fdi:010076518 fre
