Insect industrialization and prospect in commerce: A case of China.

Insects are the largest biological group on the earth, characterized by high biodiversity, easy rearing, and large populations. The utilization of insects in China has a long history and some insect species have contributed to the formation of characteristic industries. Insect products, such as silk and honey, are already familiar to the public; however, many beneficial insects and their products are not well known to most people, for example, lac insect and lac, gall aphid and Chinese gallnut, and insect wax. A new industry featuring the utilization and industrialization of insects has been rising in China. Chemically, insect products are used as raw materials; agriculturally, insects are utilized to pollinate crops for better yield; natural enemy insects have been reared to control pests; insect protein may be used for human food or animal feed; medicinally, chemical compounds may be extracted from insects as active ingredients for pharmaceutical usage; and ornamental butterfly has been applied in travel sightseeing. Insects' new purpose and function will be exploited as they gain recognition for their resources. This paper reviews insect industrialization in China and discusses the prospect of insect commerce in the future. [ABSTRACT FROM AUTHOR]
