Abstract

An attempt has been made to replicate an experiment which reported the appearance of 'miniature flies' after exposure of Drosophila melanogster larvae to the field of a pulsed diagnostic ultrasound unit. No effects were observed with 1.5 mW temporal average acoustic power, the level of the original report. However, when temporal peak powers were increased by a factor of 10, approximately one fourth of the larvae failed to survive to the imago stage. No miniature flies were seen in the entire study.

摘要

有人尝试重复一项实验，该实验报告称，将黑腹果蝇幼虫暴露于脉冲诊断超声设备的场中后出现了“微型苍蝇”。在1.5毫瓦的时间平均声功率（原始报告中的水平）下未观察到任何影响。然而，当时间峰值功率增加到原来的10倍时，约四分之一的幼虫未能存活到成虫阶段。在整个研究中未见到微型苍蝇。
