The black soldier fly (BSF), Hermetia illucens, is a generalist detritivore that is usually exploited for recycling environmental wastes, including food remnants. These insects can also be used to produce antibiotics for medical applications. For this purpose, flies need to be mass-reared using an automatic rearing system that generates various sounds. Insects use sound as a means of communication for mating or warning against predators. Thus, extrinsic sounds may interrupt the normal physiological processes of insects. In this study, we analyzed the physiological changes due to various sound treatments at 25¡ÆC and 8:16 h (L:D) photoperiod. At 95 §¼, larvae were exposed to different sound frequencies (0-5,000 §Ô). The treated larvae were adversely affected by the high-frequency sounds and showed significant reduction in pupation and adult emergence. Different sound intensities (0-105 §¼) at 5,000 §Ô caused significant changes in the pupation and survival of the adults at 85 §¼ or above. Under a stress sound condition (5,000 §Ô, 95 §¼), the BSF larvae exhibited aberrations in the expression of genes related to the immune system and digestion. These results indicate that high-frequency sound treatments at or above 85 §¼ act as a stress sound to BSF development.
