Population fluctuation of arthropods associated with different okra cultivars (Abelmoschus esculentus (L.) Moench)

Okra (Abelmoschus esculentus (L.) Moench) is a vegetable of great socioeconomic importance, cultivated in tropical and subtropical regions due to its hardiness, tolerance to high temperatures, and nutritional value. However, insect pests represent one of the main limiting factors of production. In this context, the objective of this study was to identify the population fluctuation of arthropods associated with different okra cultivars. The experiment was conducted in the experimental area of the Federal University of São Carlos, Lagoa do Sino campus (Buri-SP), between March and July 2023, evaluating insect occurrence in five cultivars: Apuim, Canindé, Cariri, Clemson Americana 80, and Santa Cruz 47. Fifteen species were recorded, with key pests including Aphis gossypii, Bemisia tabaci, Empoasca spp., stink bugs of the Pentatomidae family, and caterpillars of the Noctuidae family. The Apuim cultivar was classified as resistant, Cariri and Clemson Americana 80 showed moderate resistance, while Canindé and Santa Cruz 47 proved to be susceptible. The results highlight the relevance of varietal resistance in the sustainable management of okra.
