Studies on the types and distribution of S. damnosum adults in Imo state, Nigeria using morphometric method of identification

Abstract

Studies on the various types and distribution of adult S. damnosumcomplex in Imo Sate Nigeria were carried out between April 2004 and March 2005. The studies were conducted in three selected onchocerciasis endemic communities of the state: - Nguru/Umuaro in Ngor Okpala, Umunumo/Umuawuchi in Ihitte Uboma and Umulolo in Okigwe. Morphometric analysis of adult S. damnosumflies: (colors of forecoxa, wingtuft and antenna) showed that distinct forest flies as well as flies with both savannah and forest characteristics were present in the study area. Forest types were significantly high in abundance (77%), while the savannah type was the least (8.8%) and extremely scarce during the peak of the rains (p<0.05). .
