Abstract: Nitrogen fertilisation and carbofuran applications impact plants, yet few studies examine their general impact on plant performance and plant susceptibility to insect pests and diseases when applied together. The performance of okra (Abelmoschus esculentus L. Moench) and infestations by flea beetles in relation to nitrogen and carbofuran applications were, therefore, evaluated under a humid tropical environment. Treatments comprised of combinations of four rates of 2, 3-dihydro-2, 2-dimethylbenzofuran or carbofuran (0.0, 0.5, 1.0 and 1.5 kg ha-1) and four levels of N- fertiliser (0, 40, 80 and 120 kg ha-1). The presence of Podagrica uniformis was recorded much earlier on the plants than Nisotra sjostedti. The population of either flea beetle remained lower throughout the vegetative than the reproductive phase. While N fertilisation resulted in higher insect count than where no N was added, carbofuran at 1.0 kg ha-1 and above significantly (P
