| lymphatic filariasis in ghana: entomological investigation of transmission dynamics and intensity in communities served by irrigation systems in the upper east region of ghana. | we conducted an entomological study to document the effect of irrigation on the vectors and transmission dynamics of lymphatic filariasis in the upper east region of ghana. mosquitoes were collected by indoor spraying of houses in a cluster of communities located around irrigation projects (tono and vea) and others without reservoirs (azoka). anopheles gambiae s.s. was the dominant species and major vector, followed by an. funestus. anopheles arabiensis constituted 9--14% of the an. gambiae comp ... | 2001 | 11469943 |
