abstract
Insect pest infestation has become a major threat in the cultivation of crop which results into low yield. This experiment was conducted at Ladoke Akintola University of Technology (LAUTECH), Ogbomoso, Oyo State, Teaching and Research Farm during 2016/2017 planting season. To determine the level of insect pest infestation associated with three variety of garden egg namely (Solanum depressum, S. escullantum and S. sapienium). The experiment was arranged randomized complete block design and the variety was replicated four times. Attention was focused on insect pests of the three growth stages (Vegetative, Flowering and Fruiting stages). The result showed that there are four major insect pests of eggplant (Z. variegattus, S. litoralis, L. ornabolis). It was observed that Z. variegatus and Epilachna spp defoliate the leaf of the target crop but these insects were not found that the fruiting stage meanwhile S. litoralis and L. ornabolis heavily attacked the flowers and fruits of the target crop about 70% of fruit were destroyed before the harvesting stage except S. serpientium. However, infestation of by S. litoralis and L. ornabolis commenced five weeks after planting. Therefore, the management of insect pests of eggplant should be initiated four weeks after planting.
