A gregarisation site of Dociostaurus maroccanus (Thunb.) was studied during five annual surveys (1988-1993). The study site is on a high altitude pasture (2 300 m) in the Anti-Atlas mountains where flocks graze during the summer season. On the 2 850 ha Poa bulbosa’s pasture the number of sheeps and goats was estimated at 7 200 heads (one head per 0.4 ha). Acrididae (18 species) and their predators (14 insects and birds species) are settled around a mow meadow and irrigated cultures (55 ha). The breeding site of the Moroccan Locust is on the 2 hectares of sheep-fold. The mean density of locusts egg pods was 77/m2, of which 37 % was destroyed by Coleoptera larvae (Meloideae) and Diptera larvae. Falco naumanni Fleicher and Pyrrhocorax pyrrhoc...
