| 中文摘要:为明确粘虫Mythimna separata (Walker)蛾飞行时体温和呼吸强度等生理因素的变化,采用昆虫飞行磨固定吊飞装置,通过模拟粘虫蛾夏、秋季节不同迁飞活动的环境温度,采用半导体点温计和CO2呼吸测定仪测定了25℃和19℃条件下对其体温和呼吸强度的影响。结果表明,粘虫蛾在25℃和19℃飞行时体温均显著增加,且在15~20 min后达到最高值,然后下降并趋于稳定;在25℃飞行20 min时,雌、雄蛾最高体温分别为29.78、30.71℃,在19℃飞行15 min时,分别为22.90、22.72℃;在25℃和19℃飞行时呼吸强度显著提高,在15 min时达最高值,分别为149.98×10-6/min和106.12×10-6/min;在2种温度下粘虫蛾飞行时的呼吸强度与体温的变化呈显著正相关。研究表明,粘虫蛾在飞行时呼吸强度显著增加,体温显著升高,代谢速率和能量消耗加快,以满足其飞行的生理需求。 |

| Abstract:To clarify the changes of body temperature and respiration rate of the oriental armyworm, Mythimna separata (Walker), during flight, the body temperature and respiration rate were studied by using the semiconductor thermometer and the automatic CO2 recording equipment-infrared gas analyzer when moths were tethered to fly at 25℃ and 19℃. The results showed that the body temperatures of adults increased significantly during flight at 25℃ and 19℃, and then decreased gradually to be stable. The highest body temperatures of female and male moths were 29.78℃ and 30.71℃ at 20 min after flying at 25℃. The highest body temperatures of female and male moths were 22.90℃ and 22.72℃ at 15 min after flying at 19℃. The respiration rate of female moths increased significantly during the first 15 min and then decreased gradually to be stable, and the highest respiration rate could reach 149.98×10-6/min and 106.12×10-6/min at 25℃ and 19℃. The relationship between the changes of respiration rate and body temperature of the moth during flight was positively correlated. The results indicated that body temperature and respiration rate of M. separata significantly increased during flight so as to meet the physiological requirements. |
