西花蓟马主要寄主植物可溶性糖和蛋白质含量测定

Soluble Carbohydrate and Protein Levels in Host Plants of Frankliniella occidentalis

测定了8种植物不同器官中可溶性糖(以棉子糖、蔗糖、葡萄糖和果糖为代表)和可溶性蛋白质的含量及比例。总体上,测定的18个样品中可溶性蛋白质的含量均高于可溶性糖,可溶性蛋白质和可溶性糖比例最大为1627.00,最小为2.71,成熟叶中的可溶性糖和可溶性蛋白质的含量大多高于幼叶。辣椒中西花蓟马主要取食的花器中可溶性蛋白质含量高于叶片。

Carbohydrate（ raffinose, sucrose, glucose, and fructose）and soluble protein in 18 sample from 8 host plant species of Frankliniella occidentalis were measured. Most species of host plant examined contained a higher ratio of soluble protein to carbohydrate, with the maximum ratio was 1 627.00 and the minimum was 2.71. Mature leaves contained higher levels of soluble protein and carbohydrate than those of new leaves. Within pepper plant, the preferred feeding flowers of the thrips contained higher levels of soluble protein than the leaves.
