Abstract:

To elucidate the entomogenous fungi resources in Jiulongshan National Nature Reserve of Suichang County, Zhejiang Province, a preliminary investigation was conducted in 2024. In this study, a total of 22 specimens were collected. Morphological observations, strain isolation, and purification were performed, followed by molecular identification based on the ribosomal large subunit (LSU) and internal transcribed spacer (ITS) sequences. The results indicated that the isolated entomogenous fungi comprised 11 species across 7 genera, including 5 species of Cordyceps, 1 species of Blackwellomyces, 1 species of Beauveria, 1 species of Tolypocladium, 1 species of Ophiocordyceps, 1 species of Pleurocordyceps, and 1 species of Purpureocillium. Among these, Cordyceps was the dominant genus, with Cordyceps tenuipes being the most prevalent species. The primary hosts of these entomogenous fungi were found to be lepidopteran and hemiptera insects. This study revealed the species and host diversity of entomogenous fungi resources in Jiulongshan National Nature Reserve and provided a foundation for the further development and utilization of these resources in this region.
