      Nutrient analysis of the desert locust has shown that, about 62% of the dry weight of an adult desert locust consists of proteins, 17% as fats, with the remainder as inorganic constituents (Si, Cu, Fe, Mn, Na, K, Ca, Mg, Ti, Ni, P, S) [18,9]. Furthermore, the desert locust is easy to rear, requiring no special feeding mode.   However, the damage left behind not only remains in the realm of agricultural and environmental productivity but could be a cause for concen with respect to potential ill-health among the locust.

    The damage caused by plagues of locusts is well documented. Desert locusts in particular can swarm into groups of between 40 and 80 million creatures, devastating crops intended for human consumption. On 3rd March , a new invasion of desert locust (4 square kilometre) arrived in Bukwo District covering 3 villages of Ariyowet, Kapambar and Kaptobole in Kapswamatule sub- county. The swarm was a mixture of immature and mature adults and the UPDF immediately swung into action by spraying them.
