An experiment was conducted during two successive growing seasons of 2015 and 2016 under greenhouse condition
 )four screen-houses 9m width x 40m length x 2m height) were established for investigate the susceptibility of two sweet pepper hybrids to infestation by two spotted spider mite  Tetranychus urticae.The sweet pepper hybrids in (Kafr E1-Sheikh-El-Hamol-El-Manwfa)showed different susceptibility degree to the aforementioned pest. The data showed that liebergen was the highest density population of T.urticae in seasons of 2015 and 2016 under greenhouse while steric was low density population of T.urticae. Liebergen was the highest sensitivity while steric was the least sensitivity.Out of the two hybrids only one steric rated as low resistant against the two spotted spider mites Tetranychus urticae .The remaining hybrids showed variable degree of resistance to two spotted spider mite  Tetranychus urticae.Therefore this hybrids could be recommended for integrated pest management  program.
