The life cycle of Heterodera avenae type B on the spring wheat cv. Chamran was studied in an infested field in Behbahan District, Khuzestan Province, during 2009-2010. Soil and plant samples were taken from planting to harvest. The results showed that, the penetration of the second stage juveniles happened at temperatures of 15°C and 12°C for 17 and 15 days after the wheat sowing in early December and mid-January during 2009 and 2010, respectively. White females were observed on the roots in the late January and February in first and second year, with soil temperature 12°C to 18°C for 88-90 days after planting respectively. The male were observed in the soil, in early and late of March of the first and second year, with soil temperature ranges 16°C to 17°C, 100-118 days after planting respectively. Changing of white females to brown cysts containing eggs happened in mid-March and early April in the first and second years, at soil temperatures of 20°C to 21°C, 114-126 days after planting respectively. H. avenae type B developed only one generation per growing season and completed its life-cycle within 81-120 in Behbahan District. Total effective degree-days for completing the generation were measured 557 and 446 day degrees in 2009 and 2010 years, respectively
