The effects of fire on general abundance and distribution of soil mites and spiders at two study regions (El-Qaluobia and El-Menofia) Governorates of Egypt were recorded after wheat harvesting time during the season 2011/2012. A total of 18 mite species were collected and identified during the study period before and after fire. The collected mites were belonging to four suborders namely Astigmata (one family and one species), Prostigmata (six families and ten species), Mesostigmata (four families and six species) and Cryptostigmata (one species in one family). The collected spiders in this study were six species in five families, one of them identified in family level only (Philodromidae). Also, only one collected spider was identified as species level Hogna ferox (Lucas) (Family: Lycoseidae), and the rest of the collected families identified to genera level only. In general, mites and spiders were more abundant during two weeks before burning and reached to the lowest level during one day before and after burning. The ground layers after buring have significantly affected soil mites and spiders populations. Mites belonging to suborders Prostigmata and Mesostigmata were affected significantly by fire but Astigmata and Cryptostigmata were less affected. The abundance of spiders was significantly decreased after burning in the spider families Gnaphosidae and Lycosidae, but Oecobiidae was not affected after burning at the two regions.
