Hu1,2, Ji-Chong Zhuo1 & Chuan-Xi Zhang1 ✉  \nthe predatory bug Eocanthecona furcellata (Hemiptera: Pentatomidae) is an important natural enemy of agricultural and forest pests. In this study, we assembled a chromosome-level genome of E.furcellata using a combination of Illumina short-read sequencing, PacBio HiFi long-read sequencing, and Hi-C technology. The assembled genome has a total size of 1140.70 Mb, with a scaffold N50 of 154.55 Mb. The genome exhibits a high level of completeness, with 99.7% of conserved genes detected. Repetitive elements account for 64.33% of the genome. A total of 22,534 protein-coding genes were predicted, of which 20,803 were successfully annotated. This high-quality genome assembly provides a valuable resource for future research on the biology and ecological functions of this predatory insect.  \nBackground & Summary  \nThe Eocanthecona furcellata (Wolff) (Hemiptera: Pentatomidae) is a generalist predator that plays a vital role in biological control by preying on a wide range of agricultural and forestry pests, including species from the orders Lepidoptera1,2 and Coleoptera3. It is particularly effective against multiple lepidopteran pests that damage key crops such as rice4, maize5,6, tea7, tobacco8, mulberry9, and various vegetables10. This broad host range makes E. furcellata an important agent in integrated pest management (IPM) programs. Both nymphs and adults attack prey by piercing the integument with their stylets and injecting venomous saliva, which rapidly paralyzes and kills the host11. E. furcellata is widely distributed across tropical and subtropical regions of Asia6, 12–14. Recent studies have explored various aspects of this species, including digestive and immune-related molecular mechanisms15, 16, behavioral ecology10, 17, morphology11, 18, physiology19, and application technologies3,20,21, further validating its potential as a natural enemy in biological control systems6, 14. However, despite its ecological significance, genomic resources for E. furcellata remain limited, impeding in-depth investigations into the genetic basis of its predatory behavior, environmental adaptation, and practical applications in sustainable agriculture.  \nIn this study, we report a high-quality chromosome-level genome assembly of E.furcellata, generated using a combination of Illumina short-read sequencing, PacBio HiFi long-read sequencing, and Hi-C scaffolding. This comprehensive assembly ensures high continuity and completeness. Repetitive sequences and protein-coding genes were also predicted and annotated. The genomic dataset provided here offers a valuable foundation for future studies on the genetics, evolution, and functional biology of E. furcellata, and will facilitate the development of improved pest control strategies.  \nMethods  \nSampling. The E. furcellata strain used in this study was originally collected from Chongqing, China, in 2024 and subsequently maintained under laboratory conditions. The insects were reared on Pieris canidia larvae (Fig. 1a) at a controlled temperature of 27 ± 0.5 °C, with relative humidity above 80% and a 16-hour light/8-hour dark photoperiod.  \n1State Key Laboratory for Quality and Safety of Agro-Products, Key Laboratory of Biotechnology in Plant Protection of MARA, Zhejiang Key Laboratory of Green Plant Protection, Institute of Plant Virology, Ningbo University, Ningbo, 315211, China. 2School of Public Health, Health Science Center, Ningbo University, Ningbo, 315211, China. ✉e-mail:  \n[chxzhang@zju.edu.cn](chxzhang@zju.edu.cn)  \n[www. nature.com/scientificdata/](www. nature.com/scientificdata/)  \nFig. 1 K-mer frequency distribution and genome size estimation of E. furcellata.
