中文摘要:对亚洲小车蝗能源物质含量和消耗情况及种群密度对能源物质含量的影响进行了研究。结果表明,能源物质含量随成虫日龄的增加而发生变化,初羽化时含量较低,在10或13日龄达到最大值,之后开始下降。不同种群密度下亚洲小车蝗同日龄体内能源物质含量存在较大差异,高密度种群甘油酯含量显著的大于低密度种群,亚洲小车蝗飞行过程中主要利用糖类和脂类,但脂类是其远距离飞行的能量保证。
英文摘要:The content of energy substance and its consumption and effect of population density on energetic reserves of Oedaleus asiaticus B.Bienko were tested. The results showed that the content of energy reserves changed with days after emergence, the content were lower on eclosion of adult and at the 10 or 13 days old reached to maximum, then began to decline. The content of energy substance of same ages in O. asiaticus exhibited quite different on different population densities, the content of glyceride of high-density populations was significantly greater than the low-density populations’. About energy consumption, O. asiaticus mainly use glycogen and glyceride during flight and glyceride can ensure its long-range flight.
