| The study has been conducted on nutrient of Teleogryllus derelictus Gorochov and the correlation between nutrient and growth stage of Teleogryllus derelictus Gorochov in ordet to put up with exact science basis. Nutrient and some chemical substance of Teleogryllus derelictus Gorochov have been measured from 1 instars,3 instars,5 instars, 7 instars, 9 instars, adult of 3 days after emergence and adult of 10 days after emergence. The result as follows: The average content of protein of the different growth stages of Teleogryllus derelictus Gorochov amounts to 15.92%. It contains 18 kinds of amino acids which include 8 kinds of essential amino acids of which the content is 45.56%. It has two kinds of limiting amino acids. The fat content is 5.40%, of which unsaturated fat acids up to 57.3% and linoleic acid 25.47%. Teleogryllus derelictus Gorochov also contain 8 kinds of trace element and the higher content of Ca,Fe and Zn among them is 1164μg/g, 320.3 μg/g and 107.9μg/g respectively. Three kinds of vitamin are detected .The content of VA amouns to 436.03 μ g/l00g, VB.034 μ g/l00g and VC1.22 μ g/l00g.There are three kinds of antoxidant enzyme in Teleogryllus derelictus Gorochov . The activity of peroxidase is 1.694 U/g,catalase 9.195 U/g and superoxide dismutaase 231.7 U/g. There are active correlation between protein content and the growth stage of Teleogryllus derelictus Gorochov during its larvae and adult peiod. There are active correlation between the content of amino acids except cystine during larvae period. There are active correlation between the content of fat , total fatty acid, palmitoleic acid , Oleic acid ,Ve2,Vc and the activity of catalase and the total growth stage of it.
