The study comprised two parts, laboratory and field study to assess the potentialities of alcoholic crude extracts of the three plants species as control agents. The laboratory works: different concentrations of Alcoholic crude extracts from Khaya senegalensis (Mahogany), Boscia senegalensis (Mokhait), and Acacia nubica (La’ot) barks were prepared. The Field work: The interviews carried out during June 2006 in Zalingei area - Central Darfur State - western Sudan. The results of the interviews showed that farmers use several native plants for the solution of pest problem; these plants are naturally distributed in the area year round and handy to the farmers. This is one of the reasons that encouraged farmers to use these plants. A field experiment was conducted for two successive seasons (2017/ 2018) and (2018/2019) at the experimental farm of the Faculty of Agriculture, University of Khartoum – Shambat. Three different concentrations were compared with the negative control and positive control to study the effect of bark extracts on whitefly in Okra plant. The results justified need for further research on effect of the three plants species extracts against pests with an emphasis on more investigation to identify and determine their modes of action, stability and persistence etc... to develop the most effective components of the extracts to enable their use in Integrated Pests Management program.
