摘要

Pollination by insects accounts for over 70% of global food crop production. Among insect species, bees are some of the most efficient pollinators though their pollination efficiency varies between species. Amidst rising worries about declining pollinator populations due to human activities, understanding the diverse capabilities of pollinators is crucial for conservation. While stingless bees show promise as commercial pollinators, their capacities compared to Apis mellifera remain insufficiently understood. This study evaluated the pollination efficiency of Apis mellifera and Hypotrigona gribodoi on yield and fruit set in Capsicum annuum. The experimental design included three treatments: Apis mellifera, Hypotrigona gribodoi, and self-pollination with three replications for each treatment. Analysis of variance (ANOVA) was used to compare differences in fruit number, fruit transverse circumference, and fruit vertical circumference among Hypotrigona gribodoi, Apis mellifera, and self-pollination. The Kruskal-Wallis test was applied to compare fruit set rate, fruit weight, number of seeds, and dry seed weight. Post-hoc analyses involved Tukey’s HSD for normally distributed data and Dunn’s test for non-normally distributed data. The results show significant differences (p < 0.05) in fruit number, transverse circumference, vertical circumference, weight, and percentage fruit set rate per plant, with Hypotrigona gribodoi-pollinated Capsicum annuum performing better than Apis mellifera and self-pollination. However, there was no significant difference (p > 0.05) in the number of seeds per fruit and the weight of dry seeds per fruit among the treatments. Hypotrigona gribodoi appears to be a more efficient pollinator of Capsicum annuum L. Further research on differential pollination efficiency among species remains imperative.
