Abstract:
Agrotis spp. are destructive factors on sugar beet seedling stage. Due to the low rate of sugar beet seedling establishment at the beginning of growth, feeding activity of the insects can happen quickly and sharply reduce the number of plants. In Iran, the dominant species is Agrotis segetum that shows 95% percent of the population. The larvae feed on the leaf, crown and stem of the host. At the beginning of growth, the damage is more important. The plant density decrease by turnip moth occurs in early of the season before the six-leaf stage. The effect of different compounds to control pests on sugar beet yield was studied in Lorestan and West Azarbaijan provinces. At the beginning of the growing season treatments: Dursban (EC 40.8% 2lit /ha), Bt bait (5 lit Bt (Biolop) 50 lit water흍 kg wheat bran/ha), Bt (Biolop) Spray (3ml/1000ml), Semisolid Bt bait (100 Kg/ha) and check, were carried out in a randomized complete block design with 4 replications, seven days after emergence and then 10 days on the turnip (winter) moth, A. segetum in sugar beet fields. In West Azerbaijan province, analysis of variance showed that the increase of yield of sugar beets, related to Bt Semisolid bait treatment and significantly better than other treatments.
