This research aims to study the terrestrial crickets in the Djelfa area in different environments by calculating the relative abundance of mites that were captured by the Berlèse device. According to the results and statistics, we knew their types and percentages in 2015, where we noticed in the apple orchards affiliated with ITMAS. We registered five types of moths; three of them exceeded the 25% threshold. Trombidium sp. 29.28%; Rhyzoglyphus sp. 26,31%; Acaridae sp. 25,74% As for the observed species in the forested area, we have counted nine species, but only two species had rates that exceeded 20%. Trombidium sp. 20,83 % Rhyzoglyphus sp. 41.67% In the end, we noticed the presence of 6 species of mites in the pastoral areas, two of which were at a relatively high rate, Scutovertex sp. 43,46 % and Gamasida sp. Ind 24.61% In light of these results, we were able to identify some moth species that inhabit different environments, and we will try in the future to know their biological characteristics and their relationship to this milieu.
