dc.description.abstract The present study is designed to investigate the potentialities of Ocimum basilicum leaves powder (LP) and leaf powder –ethanolic extract (LPE) as a larvicide of Anopheles arabiensis 3rd instar larvae (L3), and comparing their results with those of the commonly used (OP) organophosphates larvicide Temephos. A cross sectional study was conducted in Barakat area to collect the anopheles larvae, identified at the first stage as Anopheles arabiensis and the third stage. To test their susceptibility to Basil extracts and Temephos as larvicide. Ocimum basilicum plant (240 g) of leaves powder were extracted by using a soxhelete apparatus for 6 hours, and 150 ml absolute ethanol . Five concentrations 2, 4, 6, 8, 10 mg/l were taken separately from basil extract. Ten larvae from third instars were transferred separately to beakers and they exposed for 24 hours. The study resulted in promising findings for malaria control by using basil as bio-agent (Basil leaves extracts LC50 of 58mg/l and LC90 of 143mg/l., Basil leaves powder LC50 of 9.19g/l and LC90 of 19.88g/l), Temephos LC50 of 0.033mg/L, and LC90 of 0.16mg/L . Using natural, botanical products are safer and environmentally friendly and more economical than using conventional insecticides in controlling the aquatic stage. Due to its easy application can be recommended to minimize the use of conventional insecticides.Temephos was found to be still effective in controlling the studied Anopheles larvae in Wad Medani, and the results indicated that these larvae did not develop resistance at a fast rate within the last 15 yr in spite of the continuous use. en_US
