Laboratory selection pressure was implemented to the adults of cowpea Aphiscraccivora ( Koche ) as well as adults of whitefly Bemisia tabaci (Gennadius) collected from Behira field-strain to build up resistance toward confidor (imidacloprid) insecticide. The level of selection pressure was carried out using LC25 and LC50 values of tested compound . After 15 generations, the level of resistance to confidor (imidacloprid) was 73.78 folds for B. tabaci and 78.40 fold for A. craccivora. The two strains showed cross-resistance to primiphos-methyl (actilic) (9.64 and 7.04 fold) for B-tabaci and A. craccivora respectively, while these strains showed high resistance to lambda-cyhalothrin (karate) and diafenthiuron ( polo) with 73.90 and 33.73 fold for A. craccivora respectively and it was 50.41 and 19.07 fold for B. tabaci respectively.
