This study reports the ecological and attachment profile of Simulium damnosun sl larvae, water physico-chemical parameters and in-situ plants associated with larvae breeding along Ogun River systems, Ogun State from March to November 2012. A line transect 50m × 50m vegetation plot measured at the four cardinal points of the breeding sites was used to calculate the frequency of occurrence of dominant flora species. Plant leaves collected were preserved and identified at the herbarium. Water temperature and pH were obtained using Hanna™ handheld temperature and pH device. Global Positioning System device was used to obtain coordinates of the sites sampled. Data were analyzed using SPSS version 17. The result revealed the abundance of Simulium larvae from March to May and a decrease in population from June to September, with subsequent increase from October to November. Studies on surrounding vegetation revealed Pterocarpus santalinoides tree (23.4%) as the most predominant and Tithonia diversifocia (7.6%) as the least vegetation. On choice of attachment, Simulium larvae preferred plant attachments (34.92%) which were of four plants species Oryza barthii, Pterocarpus santalinoides, Andropogon gayanus and Lawsonia inermis followed by submerged twigs (27.83%), rock crevices (19.84%) and decaying leaf matters (17.87%). The pH values ranged from 7.3 - 8.1, and mean temperature value was 27.8⁰C. No significant difference (p>0.05) was observed between abundance of S. damnosum sl, pH and water temperature. The results provide information on the ecology and attachment profile of Simulium damnosum s.l larval in breeding sites along Ogun River.
