摘要/Abstract

摘要： 水栖萤火虫条背萤Luciola substriata (Gorh.)发出单脉冲周期性特异闪光信号进行求偶。室外观测发现，在23℃、86% RH时，雄萤飞行求偶闪光信号脉冲闪光持续时间为0.52 s，间隔时间为0.28 s，闪光信号的最大亮度为0.6 lx；雌萤求偶信号周期为 0.67 s，最大亮度为0.4 lx。雄萤发出求偶信号0.22 s后，雌萤发出两个连续的回应信号。第一个回应信号为0.49 s，第二个为0.41 s, 两个回应信号的间隔时间为0.11 s。雄萤发现雌萤回应信号后，降落至离雌萤5～10 cm处，继续发出闪光信号，但闪光脉冲频率减小，闪光脉冲时间为1.23 s，间隔时间为0.50 s。条背萤交配时呈“V”或“一”字形交配姿势。

Abstract: Aquatic firefly Luciola substriata emits single species-specific flash signals for courtship. Under 23℃ and 86% RH, flying male adults emit flash signal with flash duration 0.52 s, interval 0.28 s, and flash intensity peak of 0.6 lx. The flash signal period of female adults is 0.67 s and the intensity peak is 0.4 lx. About 0.22 s after male advertising signal, female adults respond with two flash signals. The duration of the first response signal is 0.49 s and the second is 0.41 s. The interval of the two response signals is 0.11 s. When received the response flash signals, flying male adults land 5～10 cm near the female adults and continue to flash. At this time, the signal frequency of male adults become lower, with flash duration 1.23 s and the interval 0.5 s. Adults of L. substriata mate with copulatory position of “V" or “-" type. 
