Abstract

The Korean rhinoceros beetle (Allomyrina dichotoma) is popular as a pet and as a food ingredient, and it is commercially distributed in Korea. It is also traditionally regarded as a medicine for liver-related diseases. Recently, the Oryctes rhinoceros nudivirus was introduced from Southeast Asia. This virus is reported as a disease factor for A. dichotoma in mass-rearing facilities, and economic losses due to this viral infection have been increasing in Korea since the 2010s. In this study, we observed serious structural changes in the fat body and the intestine of virus-infected beetles. We report five genes that are up-regulated by the viral infection in the intestine: BTF3H4-like (transcription factor BTF3 homolog 4-like), SPS-like (serine proteinase stubble-like), COPB1 (coatomer protein complex, subunit beta 1), T-CP (T-complex 1 subunit gamma), and HSP70 HSP70 (heat shock protein 70). The results may provide a clue for the early diagnosis and disease-treatment that occurs in mass-rearing facilities. The improvement of stable productivity will increase the farmers’ income, and quality control of beetle-breeding will help industries to utilize this beetle as a promising food ingredient.
