Implication

Research evaluates ancient wheat interaction with insect pests, highlighting resistance and attraction implications.

Key Points

  • This study aims to evaluate the susceptibility and attractiveness of two ancient wheat varieties to storage insect pests.
  • Infested ancient wheat varieties (Padre Pio and Benedetto) with Sitophilus granarius and Rhyzopertha dominica.
  • Calculated susceptibility index for each variety using glumes on and off.
  • Analyzed volatile organic compounds with gas chromatography and assessed insect attraction using bioassays.
  • Padre Pio and Benedetto were resistant to Sitophilus granarius when hulled, and highly susceptible when de-hulled.
  • Both wheat varieties were attractive to Sitophilus granarius but not to Rhyzopertha dominica.
  • The susceptibility index correlated inversely with protein content and development time correlated directly with kernel hardness.
