Field survey of date moth insects Ephestia Spp and the parasitoid Bracon hebetor was undertaken of three different orchards in Iraq for a period of 2006 – 2007 . These orchards were in Baghdad , Kerbala and Diala provinces.The mean percent of infested variety dates Zahdi , Khadrawi and Braim on the palm trees were: 2.12 , 0.28 and 1.44 % in Baghdad ; 1.89, 0.90 and 1.80 % in Karbala and 2.68 , 0.48 and 1.71 % of Diala respectively.The total mean percent of paralyzed (infested) moth larvae of the palm trees was 26.9 % for these provinces,while the total number of different stages (egg , larva ,pupa and adult ) of parasitoid was 43 .The percentage of infested dates in these three location as mentioned above were 22.1 , 25.8 and 18.22 % ; while the paralized moth larvae were 35.7, 24.3 and 31.3 % and the total of adult parasitoids : 215; 250 and 230 in fallen dates of the three orchards, respectively .Survey of fig moth Ephestia cautella and parasitoid B.hebetor in four warehouses in Baghdad province showed that the parasitoid density increases while E.cautella density decreases .The highest density of the host (E.cautella) was at end of Apr., May and Sept. reached to 36,36 and 50 of host adults / 4 warehouses compared with 45,42 and 11/4 warehouses of parasitoid adults respectively
