Abstract: The objective of this study was to explore the main nutritional ingredients of the Larva and Pupa of Cethosia cyane, and to provide a theoretical basis for the edible development of the Larva and Pupa of C.cyane. By using nutritional analysis method,the larva and pupa of C.cyane was proved to have abundant content of mineral elements as well as 7.74% and 12.1% of fat,70.2% and 67.8% of protein.The total amino acid contents were 478.0 mg/g and 519.4 mg/g of the respective dry weights,which included 36.4% and 33.7% of essential amino acids.The element ratio of essential amino acids and nonessential amino acids were 0.57 and 0.51,respectively.Threonine was determined to be the first limiting amino acid,and Valine was the second limiting amino acid for C.cyane larva and pupa.Nutritional analysis showed that C.cyane larva and pupa had many same characters, i.e. rich protein,low fat,rich mineral elements,rich contents of essential amino acids.These results showed that C.cyane larva and pupa were insects with high nutritional value and had important economic value and broad market prospect.
