| Abstract | ||
| This study included the isolation of pathogenic bacteria Bacillus thuringiensis from different environmental sources in Diyala province, diagnosis biochemical ways, Mar 50 samples of the bacteria collected from different soils, namely, (agricultural soils and garden soils and non-agricultural soils) as well as from the water, from five districts in the province of Diyala (Baquba, Khalis, Muqdadiyah, Khanaqin, Balad Ruz) for the period from 1 9 2014 to 20 11 2014. the biochemical results Showed diagnosis and the presence of four samples and by percent 7.8% It was of a negative for transplantation bacterial and 46 sample growth by percent 90.1% It was of a growth positive for transplantation bacterial and found that 41 samples of which by percent 80.3% belong to the genus Bacillus and the species of Bacillus thuringiensis and the percentage of bacteria isolated of agricultural soils 94% and soils garden 93% and water 75%, and soils non-agricultural 44%. The results of test the effect of bio-preparation of these bacteria on the eggs of age (1-2)was significant, Since the highest rate of hatchling (1-2) and by (89%) at a concentration of 1 g / l of bio- preparation for the bacteria B. thuringiensis and lowest hatchling (0.6) and by (19%) at a concentration of 5 g / L of bio- preparation B. thuringiensis in comparison with control (3.2) and by (96%), and The results of test the effect of bio-preparation of these bacteria on the last larval phase was significant, The highest the value of the rate of highest (2.0) and by (99%) at a concentration of 5 g / L of bio- preparation for the bacteria B. thuringiensis and The less the value of the rate of loss (0.5) and by (26%) at 1g / L of bio- preparation for the bacteria B. thuringiensis concentration compared with the control treatment (0.07) and by (%3). | ||
