This  research  aim  to  know  the  ability  imago  D.  thoracicus  to  prey  C.  cramerella  at  various  growth  stadium.          This research in executing at April, 2007 up to August, 2007 in  Pest Laboratory and Entomological Faculty Of Agriculture of University  Tadulako.  Research  designed  in  Complete  Random  Device  (RAL),  consisted  of  by  four  treatment  and  three replication.  As  for  treatment  is  gift  prey  the  :  P1  (  egg  C.  cramerella),  P2  (final  larva  instars  C.  cramerella),  P3  (Pupa               C. cramerella), P4 (egg mixture, larva, pupa C. cramerella). Result of research indicate that the ability prey D. thoracicus to prey  C.  cramerella  larva  stadium  is  highest  comparing  treatment  of  egg  and  pupa,  same  thing  became  of  by  the  mixture treatment (egg, larva, pupa). Along of amount which is prey by D. thoracicus highest at larva treatment that is 2.33 - 8.33 so that big possibility of larva stadium is appropriate prey for D. thoracicus.
