The custom and culture of entomophagy in China has been preserved since ancient times, with a history going back at least 3,000 years. Presently, more than 300 species of insects with edible value have been taxonomically classified in China. These insect species belong to the orders Lepidoptera, Coleoptera, Hymenoptera, Orthoptera, Hemiptera, Isoptera, Odonata, Megaloptera, Ephemeroptera, Diptera and Blattaria, with a majority of these species belonging to Lepidoptera, Coleoptera and Hymenoptera. The most common include silkworm, tussah, Italian honeybee, oriental honeybee, mealworm, wasps, bamboo worm, locust, cicada, diving beetle and black ant. Since 2010, the number of patent applications for these edible insects has increased rapidly, indicating that the development and utilisation of edible insects in China is ongoing. The use of common edible insects primarily involves direct consumption of the insect body. In addition to fresh insects, frozen, canned and dried insects are also sold on the market. Derived extract products, such as protein, oil, chitin and insect health foods remain in the early research and experiment stages, and the current production scale is small. Bees, silkworm, mealworm and oriental migratory locust come from artificial farming, as farming techniques for these insects are well-developed. Although wasps, sand-crawling insects, bean hawkmoths and bamboo worms have been artificially cultured, the necessary technologies are underdeveloped. The majority of edible insects generally accepted by the public are still primarily collected from nature. In view of the current situation of utilisation, some suggestions have been put forward to strengthen the investigation and evaluation of edible insect resources, and research to focus on utilisation methods and artificial rearing technology in China.
