Abstract

A project to develop insect management practices for cowpea production was undertaken in the semi-arid zones of Northern Nigeria. A survey to understand the current cowpea farming practices and farmers perception of insects as a constraint to production revealed that cowpea as grown is a secondary crop requiring low inputs for the control of insect pests. Insect pests were identified as a major limiting factor in cowpea grain production. To achieve the low inputs requirements for control of the pests the combined effects of different cropping systems resistant cultivars and reduced insecticide use were examined. This was in order to develop cheaper efficient and profitable component technologies for increased cowpea production. Different profitable spray levels were obtained with resistant cowpea cultivars under both sole and cereal intercropping. Three insecticidal spray intervals at bud initiation flowering and podding stages of plant growth were identified as optimal with substantial increase in grain yield and profit margin. Intercropping cowpea with cereals decreased the numbers of some pests but this was insufficient to offset yield losses. However when the effect of intercropping was complemented with two sprays grain yields were enhanced
