以棉铃虫Helicoverpa armigera（Hübner）3龄幼虫为试验对象，研究了根皮苷、山道宁和苦杏仁苷对棉铃虫体内碳水化合物代谢的影响。桑托宁处理96小时后对幼虫的生长有明显的抑制作用，而根皮苷和苦杏仁苷对幼虫的生长影响不明显。经2 mg/ml根皮苷、山道宁和苦杏仁苷处理后，中肠海藻糖酶活性分别为对照的51.7%、32%和42.5%。在血淋巴和脂肪体中，海藻糖的量在所有情况下都减少。但山道宁对糖原和葡萄糖水平以及糖原磷酸化酶活性的影响与其他两种β-葡萄糖苷不同。3种β-葡萄糖苷对棉铃虫碳水化合物代谢的影响不同。
The purpose of this study was to evaluate the effects of three toxic β-glucosides, phlorizin, santonin, and amygdalin, on carbohydrate metabolism in the cotton bollworm, Helicoverpa armigera (Hübner), when diets mixed with β-glucosides were fed to third-instar larvae. The growth of the larvae was significantly inhibited by exposure to santonin after 96 hr but not obviously affected by phlorizin and amygdalin. The midgut trehalase activities were only 51.7%, 32%, and 42.5% of that of the control after treatment with phlorizin, santonin and amygdalin at 2 mg/ml, respectively. In the hemolymph and fat body, the amount of trehalose decreased in all cases. However, the effects of santonin on the alteration of the glycogen and glucose levels as well as the activities of glycogen phosphorylase, were different than those of the other two β-glucosides. It appears that the three β-glucosides have different influences on the carbohydrate metabolism of cotton bollworm.
