Efficient mass rearing and infestation techniques to screen for host plant resistance to maize stem borers, diatraea sp uri icon

abstract

  • One of a three-part series, this bulletin presents the techniques developed and experience accumulated at CIMMYT over the past six years in mass rearing and infestation with three maize stem borers--diatraea saccharalis Fabricius, sugarcane borer; D. grandiosella dyar, southwestern corn borer; and D. lineolata Walker, neotropical corn borer--for screening and improving host plant resistance in maize and sorghum.
