摘要/Abstract

摘要： 【目的】翅多型雄虫在繁殖方面的能量投入与雌虫相异，这种差异可能会导致雄虫飞行与繁殖权衡的生理机制发生改变。因此，本研究旨在探究翅二型长颚斗蟋Velarifictorus aspersus雄成虫在营养物质积累与分配方面是否存在飞行与繁殖的权衡关系。【方法】选取长颚斗蟋V. aspersus头幅相近的长翅和短翅型雄成虫，对羽化后7 d内两型雄成虫的体重的动态变化进行了比较，利用分光光度计法测定了两型雄成虫虫体及飞行和繁殖器官内蛋白质、总脂和糖原含量。【结果】长颚斗蟋V. aspersus长翅雄成虫在羽化后前7 d内体重保持不变，而短翅雄成虫的体重显著增加。羽化当日长、短翅雄成虫体内蛋白质含量分别为46.5±2.7和42.3±1.9 mg，二者差异显著，且长翅雄成虫羽化后体内蛋白质含量的增加速率明显高于短翅雄成虫；而羽化当日两型雄成虫体内总脂含量无显著差异，但羽化后第5和7天短翅雄成虫体内总脂含量均显著高于长翅雄成虫。成虫羽化后7 d内长翅雄成虫飞行肌内蛋白质和总脂含量均显著高于短翅雄成虫，羽化当日两型雄成虫附腺内的蛋白质与总脂含量无显著差异，但从第3天开始，短翅雄成虫附腺内蛋白质和总脂含量均显著高于长翅雄成虫。【结论】结果说明翅二型长颚斗蟋V. aspersus雄成虫体内营养物质的积累与分配方面存在飞行与繁殖的权衡关系。

Abstract: 【Aim】 For wing polymorphic insects the energy investment of males in reproduction is different from that of females, and this difference may lead to changes in the physiological mechanism of the trade-off between flight and reproduction. To test this speculation, we investigated the accumulation and allocation of nutrients in wing-dimorphic male adults of Velarifictorus aspersus. 【Methods】 We compared the temporal changes in body weight between the long-winged (LW) and short-winged (SW) male adults of V. aspersus with similar head width within 7 d after emergence. The contents of protein, total lipids and glycogen in the whole body, and flight and reproductive organs in the wing-dimorphic male adults were determined by spectrophotometry. 【Results】 The body weight of the LW male adults of V. aspersus remained unchanged within the first 7 d after emergence, while that of the SW male adults increased significantly. The protein contents in the LW males and SW males on the day of adult emergence were 46.5±2.7 and 42.3±1.9 mg, respectively, showing significant difference between the two wing morphs. In addition, the protein content increased faster in the LW male adults than in the SW male adults thereafter. The contents of total lipids in the LW and SW males showed no significant difference on the day of adult emergence, but the contents of total lipids in the SW males were significantly higher than those in the LW males on the 5th and 7th days after adult emergence. Within 7 d after adult emergence, the contents of proteins and total lipids in flight muscles of the LW males were significantly higher than that of the SW males. On the day of adult emergence, there was no significant difference in the contents of proteins and total lipids between the accessory glands of the LW and SW males. However, the contents of proteins and total lipids in the accessory glands of the SW males were significantly higher than those of the LW males from the 3rd day after adult emergence. 【Conclusion】 The results suggest that the trade-off between flight and reproduction can influence the accumulation and allocation of nutrients in wing-dimorphic male adults of V. aspersus.
