Electronic Recording of Feeding Behavior of Cnaphalocrocis medinalis (Lepidoptera: Pyralidae) on Resistant and Susceptible Rice Cultivars uri icon

abstract

  • The feeding behavior of third instars of a rice leaffolder, Cnaphalocrocis medinalis (Guenee), was recorded on resistant TKM6 and susceptible IR36 rice cultivars using an electronic monitoring device. Distinct waveforms related to spinning and feeding of larvae were recorded during feeding by C. medinalis larvae on rice leaves. On susceptible IR36 plants, larvae readily folded leaf blades and fed for sustained periods. In contrast, on resistant TKM6 plants, increased mobility of larvae reduced the effective feeding period. More leaf area was fed upon on IR36 than on TKM6 plants.
