The geographical distribution and diversity of the scorpion fauna of Egypt was examined based on a large collection covering most of the country and in view of recent revisionary systematics. Six ecologically distinct zoogeographical regions are targeted in a collection scheme. The ecological and historical biogeography of the present-day distribution of the scorpion fauna of Egypt is discussed.

The role of beta carotene (20mg/kg) and hesperidin (100mg/kg) in protection against imidacloprid (45 mg/kg, 90 mg/kg that represent 1/10 LD50 and 1/5 LD50 of IM) induced hepatotoxicity wasinvestigated. All the treatments were given orally and daily for thirty days. The treatment of rats with IM showed a significant increase in plasma aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), Gamma-glutamyltransferase (GGT), alpha fetoprotein (α-FP), total bilirubin, total cholesterol (TC) and triglycerides (TG). Also, Imidacloprid treatment led to a significant rise of hepatic malondialdehyde (MDA), tumor necrosis factor-alpha (TNF-α) and nitric oxide (N.O). On the other-hand, plasma total protein (TP) and albumin tended to a significant decrease due to IM treatment. Hepatic catalase, reduced glutathione (GSH) and superoxide dismutase (SOD) of IM group exhibited a significant decrease. The histological study showed lesions in the liver of treated rats with IM. Both beta carotene and hesperidin mitigate the deleterious effects of IM on previous parameters as manifested by a significant decrease of MDA, N.O, liver enzymes, and improved antioxidant enzyme levels and liver histology. The protective effect of beta carotene and hesperidin in combination is more pronounced. Therefore, our results clarify the synergistic effect of these two antioxidants on alleviating imidacloprid toxicity.

A twelve month measuring of some ecological factors: physic-chemical, heavy metals, organic matters and chlorophyll-a, were conducted for water and sediments in three sites: Cataract Hotel (Site1), Delta Isis (Site2) and Sakara (Site3), moorages of floating tourism ships in River Nile of Aswan Governorate. This study revealed that there is increasing in cadmium, lead, iron, zinc and phosphate and decreasing in dissolved Oxygen, in the three sites, than the permissible limit. According to law 48 (1982) for the protection of the River Nile and its tributaries from pollution, it is believed that there are a pollution of Nile water in three chosen sites may be due to many reasons discussed in details in this study.

The outer surface of insects (cuticle) is sheltered by a complex mixture of cuticular hydrocarbons (CHCs) play an important role in avoiding desiccation and defend the insects against diseases infestation. Identification and chemical analyses of insect cuticular hydrocarbons are vital practice toward insect control. The obtained results indicated the two studied species obviously differ in CHCs components (35 and 29 components characterized B. oleae and B. zonata respectively) and shared twelve components. All these components can be used (quantitatively and qualitatively) to identify and taxonomically separate them.The objective of this paper is to evaluate the using of cuticular hydrocarbons as taxonomic tools in two dipteran species, Bactrocera oleae and B. zonata.
