摘要: 黄脊竹蝗(Ceracris kiangsu)是中国南方地区重要的竹子害虫。为了揭示黄脊竹蝗发生趋尿行为的驱动力,测定了黄脊竹蝗在生长发育过程中氮素收支,分析了氮素流失与竹蝗趋泥行为间的关系。结果表明:黄脊竹蝗取食与排粪的高峰期均发生在成虫期,显著高于若虫期(P<0.001);蜕皮是造成竹蝗氮素损失的重要原因,羽化期是氮素损失的重要时期;氮素损失可能是激发黄脊竹蝗成虫趋泥行为的重要原因。

Abstract: Yellow-spined bamboo locust \[Ceracris kiangsu (Orthoptera: Oedipodidae)\] is an important pest for bamboo in southern China. To better understand the driving forces of the mud-puddling behavior of C. kiangsu, we analyzed the income and output of nitrogen during its life history and the relationship between nitrogen loss and its mudpuddling behavior. The results showed that the peak periods of feeding and excretion occurred in adult stage, which was significantly higher than those in nymphal stage (P<0.001). Exuviating was an important reason for nitrogenloss. The emergence period was the key period for nitrogen loss. In conclusion, nitrogen loss would be an important force driving the mud-puddling behavior for C. kiangsu.
