标题：EFFECTS OF DIFFERENT IRRIGATION LEVELS ON MEDITERRANEAN CORN BORER (SESAMIA NONAGRIOIDES LEFEBVRE) POPULATIONS AND EFFECTS OF FATTY ACIDS IN CORN BORER PREFERENCES
摘要：In this study, effects of different irrigation treatments (I100, I70，I35) on Mediterranean corn borer (Sesamia nonagrioides Lefebvre) populations in different corn genotypes (31D24, ADASA16, P1429) and the effects of fatty acids on corn borer preferences were investigated. The lowest fatty acid content was observed in full irrigation (I100) and the greatest fatty acid content was observed in excessive water deficit (I35) treatment. As the average of two years, the greatest yield (10400 kg ha-1), low number of alive larva + pupa per plant (3.34), tunnel length (9.44 cm) and fatty acid (2.03% ILE Eicosanoic acid, methyl ester (CAS)) were observed in I100x31D24 interaction; the lowest yield (2853.3 kg ha-1) and high fatty acid (46.03% ILE 9.12 Octadecadienoic acid (Z,Z), methyl ester (CAS)) values were observed in I35xP1429 interaction. The greatest Mediterranean corn borer population was observed in full irrigation (I100) and the lowest population was observed in excessive water deficit (I35) treatment. Mediterranean corn borer preferred the genotypes (P1429) with high fatty acid contents. It was concluded that genotypes should be tested under water-stressed and nonwater-stressed conditions for resistance to Mediterranean corn borer and alive larva, tunnel length and fatty acids could be used as screening parameters.
