Locust swarms can vary from less than one square kilometre to several hundred square kilometres with 40 to 80 million individuals per square kilometre.

A plague of the Malagasy Migratory Locust threatens the livelihoods of 13 million people, and could infect 2/3 of the country. This locust had five plagues between 1880 and 1957 and then none for the next 40 years whilst preventive control was practiced within the 25 000 km 2 , well defined outbreak area in southwestern Madagascar ( Randriamanantsoa, 1997 ). Within a 4‐year period (1997–2000) more than 42 000 km 2 of savanna grassland, woodland and dry forest were sprayed against the Malagasy migratory locust Locusta migratoria capito Saussure and the red locust Nomadacris septemfasciata (Serville) (Orthoptera: Acrididae). “Red locust have the potential to spread exclusively across the region,” said Mr Okhoba.

As the density of the population increases the locust transforms progressively from the solitary phase towards the gregarious phase with intermediate phases: Pigmentation and size of the migratory locust vary according to its phase (gregarious or solitary form) and its age. Locusts are highly mobile, and usually fly with the wind at a speed of about 15 to 20 kilometres per hour (9.3 to 12.4 mph). The project recently concluded and has seen success in controlling the locust population.
