| Abstract | ||||
| This study is concerned with subterranean termite activity A. desertorum as related to some changes in the physical and chemical characteristics of the tested soil at Aswan Governorate, Egypt. Infestation by this species is frequent in such region, where it attacks or infests the date palm trees, wood trees and soil field crops, as well as results in a greatly economic injury. Field observations and soil analysis showed that, foraging activity of A. desertorum results in various physical and chemical modifications in soil material, i.e., upward movement of fine soil particles from the subsurface dense fine textured to the surface one, which is emphasized by the relatively high contents of silt and clay fractions in soil mud tunnels and adhesive soil with P.V.C. traps (subterranean termites constrictions). Also, soil constriction materials showed more an increment in each of organic matter, total soluble salts, soluble cations & anions and low pH value than the uninfested soil material. | ||||
