Wadi Degla protectorate is located between latitudes 29° 51′ 51″ N to 30° 00′ 34″ N and longitudes 31° 16′ 03″ E to 31° 39′ 11 E and its length reached to 30 km. It passes through the limestone rocks of the Eastern Desert. The present study aimed to evaluate the oristic characteristics of the wild plants in Wadi Degla protectorate. Including taxonomic diversity, life and sex forms, dispersal types, economic potential, threats and national and global oristic distributions. Field visits were conducted to 185 locations in Wadi Degla. From each location, plant and seed specimens were collected. One hundred and sixty one plants belonged to 128 genera and 43 family were recorded. They parts of the wadi (up, mid and down-stream). Therophytes were the most represented life form. Bisexuals were the most represented sex form.Sarcochores were the most represented dispersal type, followed by Desmochores. Small geographic range -national habitat -non abundant plants were the most represented rarity form. For national scales, Mediterranean and Sinai regions were the most rich wild plants. For global scales, Saharo-Sindian and Mediterranean were the most represented elements. Medicinal plants were the most represented good, while solid wastes were the most represented threat.

Wadi Degla Protected Area (WDPA) winds through the Eastern Desert's limestone rocks, some of which rise to a height of 50 meters. The goods and services provided by Wadi Degla's natural ecosystem are the main subject of this study. In Wadi Degla, field visits were made to 185 locations. Plant and seed specimens were gathered from every site. The goods, services, and threats of the recorded species were evaluated using data from field observations and interviews with locals and herbalists. A total of 150 species were identified, along with their functions in products and services. The identified threats that cover the gradual change in the study area were recorded. Identified species offered many goods such as medicinal (111species), grazing (89) and human food (42). Also, they provide environmental benefits such as sand accumulation and windbreaks which were the most common, followed by segetal weed (27 species) and esthetic concerns (24). During the field work, we recorded pressures and threats facing the natural vegetation along WDPA. Solid wastes were the most common threat (100 %), then habitat loss (98.2%), Overcollecting and over-cutting (87.6%) Urbanization and tourism (81.4%), Climatic changes and environmental conditions (80.2%), Mining and quarrying (51.6%), Disturbance by cars or trampling (49.7%), Browsing and overgrazing (31.1%) and Clearance for agriculture (13.1%). The authors suggested that Wadi Degla's natural flora be continuously monitored and conserved because the area is losing plant habitat and may see the extinction of these species, which provide various of benefits to the environment and humanity.

The insecticidal and repellent activities of the four wild plant extracts: stinging nettle, Urtica dioica L., white henbane, Hyoscyamus albus L., camphorweeds, Pluchea dioscoridis L., and cocklebur, Xanthium strumarium L. were tested compared to the insecticide spirotetramat against the 3rd nymphal instar of Aphis gossypii Glover and adult females of Phenacoccus solenopsis Tinsley after 24 and 48 h of treatment. Their effects on acetylcholinesterase (AChE) and glutathione-S-transferase (GST) enzyme activities were also assessed to explore their possible mechanisms of action. The phenolic compounds of the plant extracts were investigated by high-performance liquid chromatography (HPLC) analysis. The most abundant compounds in the methanol extract from P. dioscoridis were gallic acid (14.45 µg/mL), and cinnamic acid (11.44 µg/mL); from U. dioica were caffeic acid (15.32 µg/mL) and syringic acid (13.47 µg/mL); from H. albus were syringic acid (7.12 µg/mL) and catechol (5.33 µg/mL); and from X. strumarium were p-coumaric acid (24.53 µg/mL) and pyrogallol (18.35 µg/mL). According to the LC50 values, the contact toxicity of U. dioica, H. albus, P. dioscoridis, and X. strumarium against A. gossypii was 40.3, 60.6, 56.2, and 32.3 mg/L, whereas, the contact toxicity against P. solenopsis was 56.4, 67.5, 64.3, and 36.2 mg/L, compared to the spirotetramat (17.2 and 24.5 mg/L), respectively, at 48 h of treatment. The highest repellency rates were observed with LC50 values for X. strumarium (63.2 and 60.3%), followed by U. dioica (46.2 and 43.5%), P. dioscoridis (45.3 and 42.8%), and H. albus extract (38.8 and 35.2%) compared to the spirotetramat (78.5 and 76.2%) against A. gossypii and P. solenopsis at 24 h, but decreased with time. The AChE and GST activities in pests were significantly inhibited, compared to control and spirotetramat, with dose and time-dependent effects. These findings indicate that tested wild extracts may be suggested as viable alternatives for aphids and mealybugs control.
