Heortia vitessoides is an important defoliator of Aquilaria trees, which produce agarwood. In this study, we used 16S rRNA gene sequencing to characterize bacteria associated with whole eggs and gut tissues from larvae, pupae, and adults of H. vitessoides. Whole egg and larval gut samples generally showed higher bacterial richness and diversity than pupal and adult gut samples. Bacterial community composition differed among the six groups examined, including whole eggs, larval guts, male pupal guts, female pupal guts, male adult guts, and female adult guts; a separate analysis of gut samples also indicated differences among larval, pupal, and adult gut communities. Proteobacteria, especially Acinetobacter, were abundant in whole egg and larval gut samples, whereas adult gut samples were dominated by Firmicutes, particularly Enterococcus. Sex-related differences were mainly observed in pupae, with Methylobacterium and Pseudomonas showing higher relative abundances in female pupae. PICRUSt2 predicted functional categories mainly related to nutrient metabolism and membrane transport. In a preliminary egg surface sterilization assay, larvae from treated eggs showed longer larval and total developmental durations than controls. Overall, these results provide baseline information on bacteria associated with whole eggs and gut tissues of H. vitessoides and identify candidate taxa for future functional studies.<\/jats:p>","DOI":"10.3390\/insects17070668","type":"journal-article","created":{"date-parts":[[2026,6,26]],"date-time":"2026-06-26T08:43:57Z","timestamp":1782463437000},"page":"668","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Bacterial Communities Associated with Whole Eggs and Gut Tissues of Heortia vitessoides Moore (Lepidoptera: Crambidae) Across Developmental Stages and Sexes"],"prefix":"10.3390","volume":"17","author":[{"given":"Pengfei","family":"Zhao","sequence":"first","affiliation":[{"name":"Institute of Highland Forest Science, Chinese Academy of Forestry, Kunming 650224, China"},{"name":"College of Forestry and Grassland, Nanjing Forestry University, Nanjing 210037, China"},{"name":"Guangxi Laboratory of Forestry, Nanning 530002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingshan","family":"Chang","sequence":"additional","affiliation":[{"name":"Guangxi Laboratory of Forestry, Nanning 530002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xuejian","family":"Jiang","sequence":"additional","affiliation":[{"name":"Guangxi Key Laboratory of Special Non-Wood Forests Cultivation and Utilization, Nanning 530002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9709-7192","authenticated-orcid":false,"given":"Ji","family":"Luo","sequence":"additional","affiliation":[{"name":"Guangxi Key Laboratory of Superior Timber Trees Resource Cultivation, Nanning 530002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qingdong","family":"Xiang","sequence":"additional","affiliation":[{"name":"Guangxi Forestry Research Institute, Nanning 530002, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhixing","family":"Lu","sequence":"additional","affiliation":[{"name":"Institute of Highland Forest Science, Chinese Academy of Forestry, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Youqing","family":"Chen","sequence":"additional","affiliation":[{"name":"Institute of Highland Forest Science, Chinese Academy of Forestry, Kunming 650224, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,6,26]]},"reference":[{"key":"ref_1","first-page":"83","article-title":"Dinamika Serangan Ulat Heortia vitessoides Moore (Lepidoptera: Crambidae) Pada Tanaman Gaharu Di Hutan Penelitian Carita, Propinsi Banten","volume":"13","author":"Kuntadi","year":"2016","journal-title":"J.
