Biological Study and integrated control of sugar beet cutworms in Shirvan

Between two cutworm species collected by light and pheromone traps in sugar beet field in Shirvan, Agrotis segetum (Lepidoprera: Noctuidae) with about 82% of the catched adults compared with A. ipsilon, was the dominant species in the region, so the biological studies were carried out on this species. According to light and pheromone traps data, flight activity of adults in the number of the catched adults by traps show, there generations per year for this species in the region. Details of biology of this pest were studied using field cages. Since chemical control is a necessity, the possibility of integrated control using poisonic bait and microbial pesticide (bactospein) in a complete randomized design including five treatments each in five replications was investigated. The average of treatments were compared using least significant difference (LSD) test. The results of a one-way anova showed a highly significant difference between treatments.
