Fig. 4From: Spatial variation of life-history traits in Bulinus truncatus, the intermediate host of schistosomes, in the context of field application of niclosamide in Côte d’IvoireEgg hatching evolution of Bulinus truncatus populations. a. In the six studied populations. b. In the two regions. c. For the two treatment statutes. Hx is mean number hatched eggs / snail / week. Age is in days. DTV-AT, STV-AT and LTV-AT are Djemitedouo, Sambakaha and Linguebo populations collected 2–3 months after niclosamide application, respectively. NCV and KCV are Noumousso and Kongobo populations from locations never treated, respectively. LTV-BT is Linguebo population collected before treatment. Abbreviations: DTV-AT = Djemitedouo test village-after treatment, STV-AT = Sambakaha test village-after treatment, LTV-AT = Linguebo test village-after treatment, LTV-BT = Linguebo test village-before treatment, NCV = Noumousso control village and KCV = Kongobo control villageBack to article page
