云南松毛虫蛹和成虫化学成分及其比较研究

On Compositions of Both Pupa and Moth of Dendrolimus houi

本文对云南松毛虫蛹和成虫的化学成分组成进行分析比较。蛹的蛋白质和几丁质含量分别为５８１．５ｇ／ｋｇ和７４．７ｇ／ｋｇ，明显低于成虫的６８３．０ｇ／ｋｇ和１７８．３ｇ／ｋｇ，而脂肪、总糖和灰分又远远高于成虫，存在极大的差异。蛹和成虫两种虫态都含１５种氨基酸，总量分别是３５９．８ｇ／ｋｇ和５０８．９ｇ／ｋｇ。蛹期的总糖含量是成虫期的５．２１倍，说明在蛹至羽化期间，有大量的糖原参与以上所提到的生命活动而被消耗。蛹的脂肪含量为２２５．２ｇ／ｋｇ，是成虫的３．４２倍。其中亚麻酸的变化尤为显著，从蛹的２２２．４ｇ／ｋｇ减少至成虫的８７．９ｇ／ｋｇ，表明亚麻酸在蛹的羽化过程中起着相当重要的作用。

This paper deals with compositions of both the pupa and moth of Dendrolimus houi. The contents of protein and chitin of pupa are 581.8 g/kg and 74.7 g/kg respectively,being lower than those of the moth 683.0 g/kg and 178.3 g/kg;while the pupas fat and carbonhydrate are obviously higher than those of the moth.Both the pupa and moth have 15 amino acids (tryptophan not attempted).The carbonhydrate in pupa is 5.21 times as much as that of the moth,demonstrating that a quantity of carbonhydrate is used up in the process of molting;and fat content of pupa is 225.2 g/kg,being 3.42 times of that of the moth;of all the fat acids,the change of linolenic acid from pupa to moth is noticeable.
