Abstract: 

Status of wheat seed gall nematode (Anguina tritici) was studied in irrigated wheat fields of Esfahan province .during 1994-97. For this purpose, 152 samples were taken from different parts of Esfahan. In the surveyed regions, 21.71% of fields were infested with the nematode in Ardestan, . Esfahan, Lenjan, Semirom, Shahreza, Fereydan, Fereydonshahr, Kashan, Mobarekeh, Najafabad and Natanz regions.
The mean of infected heads was 5.82% and crop loss estimated to be 0.3% of the total yeilds (1444 tons of wheat). The various ranges in size of the nematode galls and the population of A.tritice 12 in collected wheat samples were determined in each area.
The vaious ranges of the nematode galls were measured 2.4-5.3 x1.5-4.2mm .The maxium and minimum of second stagejuvenile (J2)in the nematod galls were culculated as 40250 and 4625 respectively. The loss of A.tritici on wheat, Roshan variety under field conditions with 4 treatments. 0.1.2 and 4% infested with galls were calculated as 0.10.68 . 21.13 and 34.93% respectively.
