Host insect species of Ophiocordyceps sinensis: a review

Abstract. Ophiocordyceps sinensis (≡ Cordyceps sinensis) is one of the most valued medicinal fungi in China, used for its invigorating effects in strengthening the body and restoring energy. The fungus parasitizes larvae of moths and converts them into sclerotia from which the fungus fruiting body grows. Since the late 1950s, considerable effort has been devoted to the study of host insects related to the fungus. In the present paper, the research history of insect species associated with Ophiocordyceps sinensis is briefly reviewed and an extensive literature survey is presented. Ninety-one insect names, spanning 13 genera, related to host insects of Ophiocordyceps sinensis are investigated. The relationships between the reported insect species and Ophiocordyceps sinensis are analyzed. Fifty-seven of these are considered as recognizable potential host species of the fungus distributed throughout the Tibetan Plateau, whilst eight are considered as indeterminate hosts and 26 as non-hosts. Among the names of recognizable potential host insects, three are invalid (nomen nudum) and require further study. This work provides basic information for management of the insect resources and for the conservation and sustainable use of Ophiocordyceps sinensis.
