      abstract = {Maize is the staple food crop and source of income for  majority of the Kenyan population and many sub-Saharan  African countries.  The increasing Kenyan population  demands an increase in maize production if intermittent  food deficits have to be averted.  Since the introduction  of improved maize varieties in mid-1960, the start of Green  Revolution period, maize yields increased drastically up to  1970s and started declining from 1980s to-date. The key  contributory factors are nutrient mining, sub-optimal input  use and insect pest damage. Of the insect pests, stalk  borer is of economic importance.  Currently, KARI and  CIMMYT are developing maize varieties that are tolerant to  stalk borer damage. In order to evaluate the potential  impact of these interventions economics of stalk borer  control at farm level was evaluated. Surveys complemented  with on-farm trials were executed in six major maize  growing zones of Kenya. Farmers were randomly selected and  a sample-frame established after which a total of 1854  households were randomly selected using random sampling  technique.  Each household was interviewed using structured  questionnaire.  Data on method of stalk borer control and  the type insecticides used was collected.  Partial budget  and economic surplus models were used. The results  indicated that very few farmers control stalk borer in  maize despite significant stalk borer losses of about 15%.  Therefore if Bt maize is introduced in Kenya it is likely  to reduce these losses. This will benefit many hungry and  poor Kenyans with improved household food supply and on  farm incomes, in line with Government policy of food  security and poverty eradication.},
