The present study was conducted in the Institute of Gum Arabic Research and Desertification Studies laboratory for three successive seasons; 2007/2008, 2008/2009 and 2009/2010). The main objective of the study is to investigate the daily food-intake and the effect of leaves stage on the total developmental period of hoppers of the tree locust, Anacridium m. melanorhodon. Sexually mature male and female adults of tree locusts were captured and kept in a cage (2 X 2 X 2metre) and left for breeding. After eggs-laying and hatching, six iron cages covered with fine wire mesh were prepared and arranged in two sets (set1 and set2). In each cage in set1 and set2, 20 1st instar hoppers were introduced; 500 gm of old and young hashab leaves were added daily to the cages in set1 and set2, respectively. Loss in weight of fresh leaves (500gm) under the lab condition was tested and subtracted from daily food-intake. The daily food consumed by the different stages of tree locust fed on old and young leaves were approximately equivalent to their body weight which ranged between 23 mg- 2000 mg for the first instar and adult, respectively. In all seasons the total developmental periodof hoppers varied; those instars which were fed on old leaves the duration was 68 days, those which were fed on young leaves the duration was 59 days, the sixth instar hadlonger duration while the first instar had shorter duration. The study concluded that both adult and hopper of tree locust can eat daily an amount of old and young hashab leaves equal to its body weight.
