Abstract
A survey study for the distribution of B. dentipes was conducted through a six big regions and all their villages in Sulymania governorate. Percentage of infestation was different through the different regions, independent on the variety of seed cultivated, ranged between 10 to 16 % for villages cultivated france variety seeds to 40 till 90 % for the others cultivated local variety seeds, except those treated their seeds with some methods of protection like hot water or deep in salt solutions, though Kalar region showed no infestation because the farmers keep the kerenels with their seeds under hot sun light during July & August. Chemical control was also carried out using three insecticides Sumicidin, Sevin and Actellic , each with two concentrations through two seasons, for the first one chemicals one time sprayed gave high infestations ranged from 26.16 for sumicidin to 33.25 % for actellic, while that of untreated plants gave 80.08 %. For the second season three times sprayed percentages of infestation were decreased significantly giving 2.70 for sumucidin to 10.70 % for actellic, while that of control was 34.30 %. The test of some other physical and chemical properties showed significant difference for weight , size , protein percent and percentage of germination between infesting and non-infesting seeds.
