Abstract
This study contains the following: 

- Bioassay for conventional and non-conventional insecticide groups: (organophosphours - pyrethroids - carbamates – insect growth regulators- naturally-derived compounds) and determination the level of resistance in several field strains.
- Selection for 6 generations of a field strains population to one traditional insecticide (chlorpyrifos) compared with one novel insecticide (spinetoram) and determination of resistance status.
- Cross resistance assay for insecticides belonging to major classes in addition to several novel insecticides.
-Biochemical studies assay (α-Esterases & b-Esterases, acetylcholinesterase, AChE , acid phosphatase (AcP) activity and alkaline phosphatase (AlkP) activity for field, susceptible  and resistance strain .
