本试验用红外线CO_2分析仪对多种昆虫的呼吸进行了测试。目的在于研究不同种类的昆虫在不同虫态或各种活动期的呼吸代谢规律性,并探讨其实用价值。初步试验结果表明,昆虫经气管系统和气门开闭机构释放CO_2的方式,分为四种类型:(1)不规则波动型,(2)等幅波动型,(3)周期爆发型,(4)周期间歇型。用小地老虎,大地老虎及棉铃虫等昆虫测试的结果,都表明夜蛾科成虫及大地老虎滞育幼虫,在晚间有明显的、不受环境因素影响的呼吸日节律;大袋蛾雌蛾在释放性信息激素时,也有明显的CO_2释放波峰。昆虫的一切活动,包括发育变态期中器官的解离和组合,滞育期的开始和终止,飞行预备期中翅肌的生长和成熟,以及启动和持续飞行等活动,都发生明显的呼吸节律变化。这些变化,均可作为生理变化的指标而加以应用。
In this experiment, the infrared CO_2 analyzer was used to test the respiration of many insects. The purpose is to study the regularity of respiratory metabolism of different species of insects at different stages or stages of activity, and to explore its practical value. Preliminary results showed that there are four types of insect release through the trachea system and valve opening and closing mechanism: (1) irregular fluctuations, (2) constant amplitude fluctuations, (3) periodic explosions, (4) ) Periodic intermittent type. The results of the tests on insects such as Small Tigers, Tigers and Bollworms showed that the adults of the armyworm and the diapause larvae of the earth tiger had obvious respiratory rhythm at night without being affected by environmental factors. Release of sex hormones, there are significant peaks of CO_2 release. All the insect activities, including the dissociation and combination of organs during the developmental metamorphosis, the beginning and termination of the diapause period, the growth and maturation of the winged muscle of the flight preparation period, as well as the start-up and sustained flight, all have obvious respiratory rhythm changes. These changes can be used as an indicator of physiological changes.
