Abstract
The  spider  Oecobius  tembli  was reared  on first  instar  larvae  of the  cotton  leafworm,  Spodoptera  litoralis (Boisd.).  Incubation  period  averaged  7.3days  for  both  sexes  at  30"C.  Both  pass through  five  spiderlings before reaching  adult stage.  The life cycle averaged 52.6 and 47.8 days for  female  and  male, respectively. Oviposition  period  averaged  4.5 days,  during  which  female  deposited  an average  of  1.5  egg  sacs.  The Total number  of consumed  prey  averaged 269.4  ard230.3  individuals  for  spider  female  and male,  respectively.
