Abstract

Description of the subject: This article presents the inventory of Orthopterans and bioecological study of the species Praephippigera pachygaster (Lucas, 1849). Objective: The aim of this study is to make an inventory, to get an idea of the dispersion of the Orthopterans and to determine which species are of economic importance in the study area. Methods: The sampling methods and the bio-ecological study make it possible to estimate the abundance of Orthopterans in the study area. Results: The investigation results indicate 25 species belonging to 11 sub-families and five families. The distribution of Orthoptera species between study stations indicates that the Belezma station remains the richest with 22 species while the Ain Djasser station is the lowest with only five species. The bioecological study of the species Praephippigera pachygaster (Lucas, 1849) of the Tettigoniidae family shows that this species is polyphagous with a preference for family plants: Asteracae and Poaceae. This species occurs in Khenchela region with a marked outbreak during the study period. Conclusion: The study of the diversity and structure of the Orthopteran population shows that the study area is diverse (25 species). The species Ocneridia volxemii, Dosiostaurus maroccanus and P. pachygaster seem to be the most of economic important species in the Aures region.
