Soil Fauna Biodiversity in Apricot Orchard at Tkout (Batna–East of Algeria)

Soil organisms contribute significantly to biodiversity and ecosystem functioning. In this context (It is in this light that) we found it useful to study soil fauna community in an orchard of apricot based in Tkout (Batna). This study was conducted from March 2012 to February 2013. Different sampling techniques were combined: TSBF, Barber pots, food traps and repellent traps. We have surveyed a total of 45 species thatare divided into6classes. Insects class is the most dominant with 36 species distributed among 25 families and 6 orders in which Coleopteran order is the most represented quantitatively. A great diversity of organisms belonging to the 6 main groups of soil invertebrates is represented (Insects, Myriapods, Arachnids, Crustaceans, Molluscs and Annelids). The herbivores are the most dominant food category in our inventory and the total wealth varies among months and seasons. It would be very useful to take realize this inventory over several years and supplemented by further studies on the bio-ecology of species that are very harmful and those of biological interest both on the ground and to this precious speculation which have a socio-economic interest as well as ecological one in Tʹkout area.
