This study was conducted in 1995/96 as an on-farm experiment with direct paJ1icipation of some selected farmers at three locations in Abu Naama, southern Blue Nile region. The primary objective was to investigate the benefits of intercropping as a simple and low-cost IPM component in reducing pest densities on vegetable crops. The results showed that the population density of a key pest on a host-plant in a monoculture was higher than when it was in a polyculture. Intercropping tomato/eggplant and tomato/cowpea favoured higher population densities of whitefly on tomato. Intercropping tomato/onion reduced whitefly population density on onion. Intercropping cowpea tomato or cowpea/onion increased the population density of Bemisia tabaci on cowpea. Intercropping cowpea/eggplant reduced the whitefly population density on eggplant. Similarly, intercropping eggplant/tomato or eggplant/onion increased jassid numbers on eggplant. Intercropping eggplant/cowpea reduced jassid density on eggplant. Intercropping onion/tomato and onion/eggplant also, did increase thrips population density on onion, while intercropping onion/cowpea decreased thrips density on onion. The opposite was also true for the onion yield. Results of crop yield followed a similar trend, i.e., lower pest population densities reflected higher crop yields, while higher population densities gave lower crop yields
