Research interests

• My Research Program Has Focused On Isolation Of More Toxic Indigenous B. Thuringiensis Isolates From Egyptian Soils
• Diseased Insects.&Nbsp; Moreover
• Evaluation Of The Potential Activity Of These Isolates Against Some Economically Important Lepidopterous Cotton Insect Pests Namely
• The Cotton Leafworm Spodoptera Littoralis (Biosduval)
• The American Bollworm Helicoverpa (=Heliothis) Armigera (Hardwick)
• The Pink Bollworm Pectinophora Gossypiella (Saunders)
• The Greasy Cutworm Agrotis Ypsilon (Rottenberg) Causing Great Damage.&Nbsp; The Mode Of Action Of Some Of These Isolates Has To Be Investigated Based On Studies Of The Histopathological Effects Of B. Thuringiensis On S. Littoralis
• P. Gossypiella Midguts Using Scan Electron Microscope (Sem)
• Transmission Electron Microscope (Tem).&Nbsp; Also
• My Research Program Utilizes Molecular Biology Tools To Study Molecular Characterization Of The B. Thuringiensis Isolates
• Show The Genetic Variability Among Different Isolates
• Its Correlation With Their Potency Against The Target Lepidopterous Insects
• To Explore The Possible Development Of More Effective Formulations Of B. Thuringiensis For Field Application. Moreover
• Establishment Of Efficient Regeneration System For Tomato Cultivar As Pre-Requisites For The Development Of Transgenic Plants Was Performed.&Nbsp; The Transgenic Tomato Plant Harboring Cry 2Ab Gene In Its Genetic Makeup Was Made Using Gene Transfer Protocol.&Nbsp; The Bt-Tomato Plants Have Autoresistance Against The Lepidopterous Insects Namely
• H. Armigera
• S. Littoralis
• P. Operculella.&Nbsp; Especially
• The Expression Of Δ-Endotoxins In Transgenic Plants Has Provided A Very Effective Means To Control Economically Important Insect Pests.&Nbsp;&Nbsp
