This book was written by a layman who took part in the regular survey work in the Sahara, Arabia and Iran in connection with the prevention of outbreaks of Schistocerca gregaria (Forsk.) from January onwards and witnessed the control operations put into effect in Ethiopia and the Sudan when a new cycle of outbreaks began in Africa and Arabia in the winter of
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.

Damage caused by desert locusts can be devastating, although — owing to the insect’s mobility — it is never uniformly distributed. Keith Cressman, in Biological and Environmental Hazards, Risks, and Disasters, Abstract.
The desert locust is considered to be the most dangerous of all migratory pest species in the world due to its ability to reproduce rapidly, migrate long distances, and devastate crops. In order to minimize the frequency, severity, and duration of plagues, the Food and Agriculture Organization (FAO.

Locusts are voracious feeders, eating up to their body weight daily. They damage crops by devouring all parts of the plants and also by breaking trees by their sheer weight when they settle down in masses. The potential role of plant structure and quality as well as its distribution on locust populations needs further clarification.
