Field Evaluation of Cotesia flavipes Cameron (Hymenoptera: Braconidae) (Indonesian Strain) against Sugarcane Stalk and Internode Borers


  • Indian Institute of Sugarcane Research, Division of Entomology, Lucknow, Uttar Pradesh, 226 002, India


Field trials were conducted on the releases of Cotesia flavipes Cameron (Indonesian strain) against sugarcane stalk (Chilo auricilius Dudg.) and internode (Chilo sacchariphagus indicus Kapur) borers at IISR Farm, Lucknow for consecutive three crop seasons 1996-97 to 1998-99. The parasitoids were released in one block @ 2000 mated females/ha/month split into four doses from July to October and the other block was treated as check. The results indicated reduction of 56.2, 69.6 and 43.1 per cent in stalk borer infestation in parasitoid released blocks as compared to check, in October during 1996-97, 1997-98 and 1998-99, respectively. The results remained inconclusive in cases of internode borer due to low infestation.
