| description | The Enneothrips flavens is considered a pest which limits the production of peanuts, as the use of resistant cultivars prevents or reduces insecticide application providing greater security and profitability to the activity. The study aimed at evaluating thrip resistance, and productive potential of peanut genotypes. The experiment was conducted at the Department of Agronomy, IFMT Campus São Vincente, MT, during the period of sowing waters on Nov. 11, 2010, with these crawling growth habit genotypes: Nahuel, Caiapó IAC, IAC Jumbo, Horse, Tégua and IAC 5024. A completely random design with four replications was adopted. Each experimental unit consisted of four 5 m long rows. The study performed counts for adult and nymph thrips; evaluations of damage symptoms (we used a scale ranging from 1 to 9 according to the percentage attack of the blade, as follows: 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80% and 90%) of leaf area, plant height and production. Results show thatm for rated crawling growth habit genotypes, the largest population of E. flavens occurs from 51 to 72 days after emergence (DAE) of plants. The IAC 5024 is more susceptible to E. flavens while IAC Caiapó and Horse behave like Horse and Nahuel resistants. Horse and Nahuel genotypes present higher yields and return of peanuts and grains. |
