A study was carried out on the effects of chemical constituents on insect pest attack on genotypes in West African Okra, Abelmoschus caillei. The growth and yield response of the genotypes to pest infestation was determined. The biochemical analysis was carried out using the seeds of the genotypes to determine the bioactive ingredients content. Field experiment was laid out in Randomized Complete Block Design (RCBD) with four replications. The result indicated that three of the genotypes, (CEN 010, , NGAE-96-0123 and NGAE -960067) attracted less number of insects, recorded lower percentage of leaf damage (27.19%, 27.41% and 31.73%) and percentage pod damage ( 22.06%, 35.68% and 40.46%) and recorded higher level of harmful bioactive ingredients which conferred resistance to insect attack compared to the susceptible ones. The result of correlation analysis carried out between seed yield and the other traits show that a significant and positive exists between number of fruits per plant and number of damaged pods; number of insect feeding holes and number of Podagrica spp.; number of damaged pods and number of Dysdercus superstitiosus. A negative correlation also exists between number of damaged leaves, number of Dysdercus superstitiosus, number of insect feeding holes,number of Podagrica spp. and seed yield. From the study, it can be concluded that antixenosis was the basis of resistance to insect attack. Three of the genotypes (NGAE96-0067, NGAE-96-123 and CEN 010) used in this study are therefore recommended to farmers because of their economic value inspite of insect attack.
