中文摘要：选择武汉城区4种不同的水质作为影响因子，通过室内实验，研究武汉城区4种不同水质对雷氏黄萤Luciola leii Fu and Ballantyne 幼虫呼吸行为的影响，探讨利用雷氏黄萤幼虫的呼吸指标作为监测多污染源混合废水的可行性。结果表明，Ⅲ类（东湖）、Ⅳ类（汤逊湖）、Ⅴ类（野芷湖）和劣Ⅴ类（南湖）四类水质与CK相比较，对雷氏黄萤幼虫昼夜的呼吸行为均有影响。雷氏黄萤幼虫刚接触Ⅲ类、Ⅳ类、Ⅴ类和劣Ⅴ类水质均有明显反应。在劣Ⅴ类水质条件下，雷氏黄萤幼虫的呼吸持续时间和呼吸频率（FR）均高于Ⅲ类、Ⅳ类、Ⅴ类水质，呼吸间隔时间（SI）均低于Ⅲ类、Ⅳ类、Ⅴ类水质。提示雷氏黄萤幼虫的昼夜呼吸行为、呼吸持续时间、呼吸频率（FR）、呼吸间隔时间（SI）可作为多污染源混合废水的敏感生物学监测指标。
英文摘要：The effects water quality in urban waters of Wuhan on the larval respiratory behavior of Luciola leii Fu and Ballantyne (Coleoptera: Lampyridae) were evaluated in laboratory, and the feasibility of using indexes of the insect respiratory behavior to monitor multi_polluted and mixed waste water were discasse. The results showed that the larval respiratory behavior of L. leii in lighted and dark conditions (simulating daylight and night_time) was influenced by type Ⅲ (Donghu lake), type Ⅳ (Tangxun lake), type Ⅴ (Yezhi lake) and type inferior Ⅴ (Nanhu lake) water qualities, compared with indoor tap water (CK). The larvae had obviously different responses when they were put into type Ⅲ, type Ⅳ, type Ⅴ and type inferior Ⅴ water qualities. Under type inferior Ⅴ water qualities conditions, the time of respiration and respiratory frequency (FR) were higher than those under type Ⅲ, type Ⅳ, and type Ⅴwater qualities, and the subsurface interval duration (SI) was shorter than those under type Ⅲ, type Ⅳ, and type Ⅴwater qualities. It vealed that the respiratory behavior of L. leii in day and night (specifically the time of respiration, FR, and SI) could be used as index of monitoring water quality for multi_polluted and mixed waste water.
