From 2005 to 2008, with the support of the Ministry of Science and Technology (MOST), the construction of parasite germplasm repositories has spread to 20 conservation institutions in 15 provinces (cities) nationwide, with 3 physical exhibition halls; 3 live parasite conservation centers. A total of 1115 species/117814 pieces of parasitic germplasm resources of 23 orders in 11 phyla have been integrated into the physical library and database, including human parasites and vectors, animal parasites, plant nematodes, medical insects, trematodes, and parasitic snails, and the resources are combined with moderate distribution, medium- and long-term support, and off-site duplicates. The number of resources accounts for 39.27% of the national total. Through 10 years of accumulation, we have built the largest and only parasite species resource database in the field of parasites in China, and created a sharing platform of parasite germplasm resource center.
