19. Insect pest management and socio-economic circumstances of small-scale farmers for food crop production in western Kenya: a case study.

Insect Sci. Applic., 10, 4, 1989, pp. 443-462

The survey reported here involved interviews with 150 farmers in Western Kenya and was based on a questionnaire which comprised six sections.

Five sections covered the farmers' background, farming practices, pest problems and their control, socio-economic conditions, and accessibility/willingness of the farmers to participate in the project.

The last section included field observations on the insect pests of sorghum, maize and cowpea.

On the basis of the information obtained on above-mentioned aspects, criteria were defined for selecting 25 farmers in each division for on-farm trials.

Concluding, the following measures that need to be taken to counter the limitations and thereby assist the farmers in increasing food production can be recommended:

 

- Cultural practices like early planting, intercropping of appropriate crop combinations and destruction of crop residues help to suppress borer attack.

 

- Destruction of crop residues, though practised by some farmers, is not practised by the others, either because they are not aware of the advantage for pest control or because they use the crop residues in other ways. It is, therefore, important that the farmers in the project area are fully informed about the benefit of proper disposal of crop residues.

- Growing cultivars resistant or tolerant to pests is another important and widely accepted component of insect pest management. But most of the cultivars in use have little resistance to the borers.

 

There is an urgent need to make the farmers fully aware of the existence of resistant cultivars and to provide seed for cultivation.

- Pesticides are hardly used by most farmers in the project area. In view of their hazardous effects, and the dangers of misuse due to poor information, their use by the farmers should be discouraged.
