Abstract
The  life  history  of the  spider  mite,  Tetranychus cucurbitacearum  (Sayed)  was investigated  on  six  eggplant  cultivars ("White",  "Black  Stream beity",  "Baladi",  "Black  king", "Roma"  and "Taska")  at 25  & 35+2°C  and  70+5% R.H. "Taska"  cultivar shortened  the  life  cycle  to  10.08  and  6.93  days  at25  and  35'C;  while  "White"  cultivar prolonged  this period  to  16.28  and 10.61  days.  The  high egg production  per female  was  on  Taska  cultivar  (70.70  & 47.58 eggs)  with  a daily  rate  of 7.08  & 5.50  egg/female  at25  and  35°C,  respectively.  The  low  egg  production  per female  was on  White cultivar  (41  .66  & 29.42  eggs) with  a daily  rate  7 .38  & 7 .99  egg/female,  respectively  at  the  same  previous  conditions.
