Abstract
A study on the orthopterologic diversity was
performed in three different agro-ecosystems in northern
Algeria, located at Baba-Ali, Ain-Taya and Cap-Djinet. The
first two stations are part of the plain of Mitidja. Inventories
carried out were conducted over a period of 12 months;
November-December 1996/1997 for Baba-Ali and Ain-Taya
stations, and September-August 2010/2011 for Cap-Djinet
station. The settlement of the identified orthopteric revealed
a total of 25 species, 8 Ensifera and 17 Caelifera. Acrididae
Family accounts only 15 species are spread over 6
subfamilies, 60% of the identified orthopterofauna. The
highest total richness and the specific average richness per
survey and station values were recorded in October 1997: 8 –
4, 2 Baba-Ali, 10-5,2 Ain-Taya; and in August 2011: 13 – 6,2
Cap-Djinet. According to the Shannon-Weaver diversity
index, the surveyed areas have a diverse orthopterofauna
particularly in spring and autumn when the number of
individuals is equally distributed between species (0,62 < E <
0, 97).
