中文摘要:为明确意大利蝗Calliptamus italicus（L.）卵越冬过程中的呼吸代谢变化，通过定期解剖野外意大利蝗卵观察其胚胎发育进度，并应用多通道昆虫呼吸代谢测量系统逐月测定意大利蝗卵的O₂消耗率、CO₂释放率、代谢率和呼吸商，分析其变化特征，同时对其越冬环境温度进行实时测定。结果表明，意大利蝗卵的呼吸代谢水平随着越冬时间的推进发生季节性波动。越冬前（8-10月），意大利蝗卵的呼吸代谢水平较高，其中在8月间最高，此时胚胎发育较快，且复眼背部边缘在10月出现红色；越冬期间（11月-翌年2月），呼吸代谢水平在11月间最低，在12月-翌年2月之间则无显著差异，复眼颜色逐渐加深，胚胎发育基本停滞；越冬结束后（翌年3-4月），呼吸代谢水平逐渐升高，在翌年4月间显著高于10月-翌年3月，但显著低于8月，此时发生胚胎转动且恢复发育。越冬过程中，意大利蝗卵呼吸商均大于0.94。不同月份意大利蝗卵的O₂消耗率、CO₂释放率、代谢率与5 cm地温之间均呈显著正相关，相关系数分别为0.857、0.831和0.902。在整个越冬过程中，意大利蝗卵的呼吸代谢变化与其胚胎发育进度以及环境温度密切相关，且蝗卵均以糖类为主要能源物质，以最大程度减少物质能量消耗，从而确保蝗卵的正常发育、越冬及来年的顺利孵化。

Abstract:To clarify the changes of respiratory metabolism in overwintering eggs of Italian locust Calliptamus italicus(L.), locust eggs were dissected regularly to observe embryonic development progress, and O₂ consumption rate, CO₂ release rate, metabolic rate and respiratory quotient were measured using Sable multi-channel insect respiratory metabolism measurement systems and analyzed from August to April of the next year. The environmental temperature of locust eggs in the wild was measured. The results showed that respiratory metabolism level of locust eggs fluctuated seasonally with the advance of overwintering time. In pre-winter (August-October), respiratory metabolism level of locust eggs was higher, and the highest respiratory metabolism level was observed in August. At this satge, embryos developed fastly and the red pigment appeared in the back edge of the compound eyes in October. During the winter (November-Feburary), respiratory metabolism level was the lowest in November, but no significace was observed during this period. The color of the compound eyes darkened and the embryo development basically stagnated. In post-winter (March-April), respiratory metabolism level gradually increased. Respiratory metabolism level in April was significantly higher than that in October-March, but significantly lower than that in August. During this period, embryo transfer occurred and the embryos recovered development. During the whole overwintering progress, respiratory quotients of locust eggs were higher than 0.94. The correlation coefficients between O₂ consumption rate, CO₂ release rate, metabolic rate and 5-cm ground temperature in different months were 0.857, 0.831, 0.902, respectively; there was a positive correlation between the respiratory metabolism of locust eggs and 5-cm ground temperature. The respiratory metabolism level of C. italicus eggs were closely related to their embryonic development and the environmental temperature during the whole overwintering process. Carbohydrates were the main energy sources of locust eggs, which could minimize the energy consumption to ensure normal development, successful overwintering and incubation of locust eggs in the coming year.
