This study investigated the species composition and diversity of Hymenoptera in a conventionally managed pummelo (Citrus maxima (Burm.) Merr.) orchard in Xishuangbanna, Yunnan Province, China, from February 2025 to February 2026. A total of 8446 specimens were collected using Malaise traps and sweep netting, belonging to 11 superfamilies, 37 families, and 191 morphospecies. The community was dominated by parasitoids (140 morphospecies, 73.30%), followed by predators (30 morphospecies, 15.71%), pollinators (18 morphospecies, 9.42%), and phytophagous gall-inducers (3 morphospecies, 1.57%). Ichneumonoidea (42 morphospecies, 21.99%), Chalcidoidea (35 morphospecies, 18.32%), Vespoidea (30 morphospecies, 15.71%) and Apoidea (28 morphospecies, 14.66%) were the dominant superfamilies, collectively accounting for 70.68% of all morphospecies. At the family level, Ichneumonidae (25 morphospecies), Braconidae (17 morphospecies), Bethylidae (13 morphospecies), and Pompilidae and Scelionidae (11 morphospecies each) were the most morphospecies-rich families. Shannon-Wiener diversity was higher at the family level (H' = 2.9340) than at the superfamily level (H' = 2.0302), indicating greater heterogeneity at a finer taxonomic resolution. These results demonstrate that the surveyed pummelo orchard in Xishuangbanna harbors a species-rich and functionally diverse hymenopteran community with substantial potential for biological pest control and pollination services.PMID:42783254 | DOI:10.3390/insects17090886
