Occurrence of Soil Mites in Relation to Soil Analysis at Sharkia Governorate

Abstract

This investigation was carried out to throw light on the occurrence and distribution of mites inhabiting soil planted with onion and garlic plants during the season 2009-2010 at Sharkia Governorate. Twenty three species belonging to four suborders were collected. Actinedida was represented by six families, Gamasida (5 families), Oribatida (3 families) and Acaridida (one family). Results cleared that Actinedida and Oribatida were the most dominant in onion and garlic soils, contributing by 35.16 and 41.38 % of total mites, respectively. Furthermore, December seemed to be the most numerical compared with other tested months. Data also, demonstrated that soil mites diversity was positively related to both organic matter and N+.
