- My research program has focused on isolation of more toxic indigenous B. thuringiensis isolates from Egyptian soils and diseased insects.
- 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) and the greasy cutworm Agrotis ypsilon (Rottenberg) causing great damage.
- 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 and P. gossypiella midguts using Scan Electron Microscope (SEM) and Transmission Electron Microscope (TEM).
- Also, my research program utilizes molecular biology tools to study molecular characterization of the B. thuringiensis isolates and show the genetic variability among different isolates and its correlation with their potency against the target lepidopterous insects and 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.
- The transgenic tomato plant harboring Cry 2Ab gene in its genetic makeup was made using gene transfer protocol.
- The Bt-tomato plants have autoresistance against the lepidopterous insects namely, H. armigera, S. littoralis and P. operculella.
- Especially, the expression of δ-endotoxins in transgenic plants has provided a very effective means to control economically important insect pests.
