Tomato production is constrained by arthropod pests which cause significant damage reducing both quality and quantity of the yields. These arthropod pests include tomato leaf miner, whitefly and red spider mite. Over-reliance and use of chemical pesticides to control these pests have led to the loss of efficacy against them. Host plant resistance, a key component in Integrated Pest Management as a long term intervention has guided the evaluation of seven tomato varieties, namely; GKB-032375, GKB-043431, GKB-034777 (wild tomato varieties) and commercial varieties; Oxyl, Eden F1, Rio-Grande, and Cal-J to their relative resistance to tomato leaf miner, whitefly and red spider mite infestation under greenhouse conditions. This paper gives findings of the varieties evaluated and their relative resistance to these three pests under evaluation. Tomato breeding mainly aims at fruit quality and yield, ability to tolerate abiotic factors and resistance to biotic stress. GKB-032375 showed a higher resistance level to all three pests compared to the other varieties under evaluation. These results suggest that breeding programs be aimed at introducing resistance alleles present in the GKB-032375 variety into the commercially cultivated tomato varieties to lower densities of pest complex and reduce dependency on chemical pesticides in pest management.
