Watermelon (Citrullus lanatus Thunb.) is a significant horticultural crop grown worldwide, prized for its sweet, juicy and nutritious value. As with many flowering plants, watermelons depend on pollinators for fruit set. Insect pollinators are essential in increasing seed set of many pollination-dependent fruit crops, as well as the quality of seed or fruit in terms of nutrient and mineral composition. This study was conducted at Federal University Wukari during 2024 late planting season and 2025 early planting season to determine the impact of insect pollinators on yield and fruit quality of watermelon across the seasons. The study was carried out on six 5 x 3 m = 15 m2 plots demarcated on a 0.108 ha land. The plots were grouped into two with three replications. The first group was covered with net mesh for insect pollination exclusion at 50% flowering stage while the second group was left open to allow for insect pollination. There was a significantly (p 0.05) in the early season. Total Soluble Solids (TSS), were also elevated in late season fruit from insect-visited plot (10.00 ± 0.12 °Brix against 6.63 ± 0.22 °Brix) and pooled means of early and late planting season (10.37 ± 0.17 °Brix against 8.58 ± 0.88 °Brix). The finding showed that insect pollinators have significant role in enhancing the yield and fruit quality of watermelon, underscoring the necessity of conservation of insect diversity.
