Larvae of the black soldier fly (BSF) Hermetia illucens (L.) (Diptera: Stratiomyidae) are promising organisms to be used for organic waste bioconversion. Breeding BSF indoors has been suggested as a cost-effective approach for countries with long winters or low sunlight levels through the year. As the BSF mating is visually mediated, artificial illumination conditions are critical to a successful indoor breeding system. In this study, we tested four different types of artificial light sources for their effects on BSF mating success. They included: (1) a halogen lamp; (2) a combination of a white light-emitting diode (LED) lamp and a fluorescent ultra violet lamp; (3) a metal halide lamp, and (4) a specially designed light-emitting diode (BSFLED) lamp, whose design was based on the specific BSF adult visual spectral sensitivity. We determined the spectra of four artificial light sources, compared their spectral composition in relation to the BSF-visible spectrum, and compared their effects on the mating success of two different BSF colonies. BSFLED was the most energy efficient light source in spectral composition and led to the highest mating success in terms of the percentage of inseminated females and fertile clutches. Thus, BSFLED is the most suitable light source tested in our experiment for breeding BSF indoors. The colony effect and possible light flickering effect on BSF mating success were also detected. The implications of these findings are discussed.

在四个人造光源下，黑士兵苍蝇Hermetia illucens（Diptera：Stratiomyidae）的交配成功。

黑人士兵蝇（BSF）的Hermetia illucens（L。）（双翅目：Stratiomyidae）的幼虫是有前途的生物，可用于有机废物的生物转化。对于一年四季冬季长或阳光低的国家，有人建议在室内繁殖BSF是一种经济有效的方法。由于BSF交配是通过视觉介导的，因此人工照明条件对于成功的室内繁殖系统至关重要。在这项研究中，我们测试了四种不同类型的人造光源对BSF交配成功的影响。其中包括：（1）卤素灯；（2）白光二极管灯和荧光紫外灯的组合；（3）金属卤化物灯，和（4）特殊设计的发光二极管（BSFLED）灯，其设计基于特定的BSF成人视觉光谱灵敏度。我们确定了四个人造光源的光谱，比较了它们与BSF可见光谱的光谱成分，并比较了它们对两个不同BSF菌落交配成功的影响。BSFLED是光谱成分中最节能的光源，并且在授精雌性和可育离合器的百分比方面导致了最高的配对成功率。因此，BSFLED是我们在室内繁殖BSF的实验中测试的最合适的光源。还检测了菌落效应和可能的闪烁效应对BSF交配成功的影响。讨论了这些发现的含义。BSFLED是光谱成分中最节能的光源，并且在授精雌性和可育离合器的百分比方面导致了最高的配对成功率。因此，BSFLED是我们在室内繁殖BSF的实验中测试的最合适的光源。还检测了菌落效应和可能的闪烁效应对BSF交配成功的影响。讨论了这些发现的含义。BSFLED是光谱成分中最节能的光源，并且在授精雌性和可育离合器的百分比方面实现了最高的配对成功率。因此，BSFLED是我们在室内繁殖BSF的实验中测试的最合适的光源。还检测了菌落效应和可能的闪烁效应对BSF交配成功的影响。讨论了这些发现的含义。
