The present study was conducted in two locations in Acacia Agricultural Company (Nawa and Elrahad locations) for three successive seasons; 2007/2008, 2008/2009 and 2009/2010). The main objective of the study was to test for the occurrence of adults and hoppers of the tree locust, Anacridium melanorhodon in relation to the prevailed rainfall and relative humidity. Rainfall and relative humidity data was collected from Elobeid Metrological Station. Visual counting of both hoppers and adults was done weekly early in the morning (8 o’clock) with four persons in all directions without much disturbance. Adults were found throughout the year except during February, March and April, while hoppers appeared in July, August, September and October. The study concluded that the study area represents a suitable media for tree locust roosting and landing most of the year.
