| Abstract: | A field study was carried out in the riceirrigation scheme Office du Niger,Mali, to observe malaria mosquito larvaldevelopment as related to differences infield irrigation practices, such as waterlevel, irrigation application andirrigation frequency. The main aim was tofind out to what extent field watermanagement can be considered as a tool forvector control for this irrigation system.The results show that minor differences inwater management do result in smalldifferences in mosquito development, withrespect to larval densities and speciescomposition. The main malaria vector forthe area, An. gambiae s.l., developedpredominantly in the first six weeks aftertransplanting. Due to improper drainageafter harvest An. gambiae s.l. breeding quickly re-established on fieldswhere small water pools remained. Althoughfurther research is needed, suggestions formosquito control in the Office duNiger would be a strict performance of theagricultural calendar in combination with arotation of transplanting in largeblocks. |
