从变害为利的观点和昆虫资源利用的角度出发，探讨两种松毛虫蛹的营养价值．云南松毛虫（ＤｅｎｄｒｏｉｍｕｓｈｏｕｉＬａｊｏｎｑｕｉｅｒｅ）蛹的蛋白质、氨基酸、脂肪和碳水化合物的含量分别为５８１５％，３５９８％，２２５２％和６８２％；文山松毛虫（ＤｐｕｎｃｔａｔｕｓｗｅｎｓｈａｎｅｎｓｉｓＴｓａｉｅｔＬｉｕ）蛹分别为６１２６％，３８９２％，１９７５％和９７０％；前者的不饱和脂肪酸含量与Ｐ／Ｓ值分别为６３５９％和１７６３％，后者分别为６１６９４４％和１６３１６％；必需脂肪酸分别为３２２０２８％和２８４０％；两种虫蛹皆含有多种维生素和丰富的矿物元素． From the point of view of changing from harmful to beneficial and the utilization of insect resources, the nutritional value of two kinds of pine caterpillars was discussed. The contents of protein, amino acid, fat and carbohydrate of pupae in Dendroimus houi-lajonquiere were 5815%, 3598%, 2252% and 682%, respectively. The pupae of D. puncti wenshanensis TsaietLiu 6126%, 3892%, 1975% and 970% respectively. The content of unsaturated fatty acid and P / S of the former were 6359% and 1763%, and the latter were 611%. 6944% and 16316%, respectively. The essential fatty acids were 322028% and 2840% respectively. Both pupae contained multiple vitamins and rich mineral elements.
