RETRACTION
ECOLOGY. For the article "Monarch butterflies (Danaus plexippus L.) use a magnetic compass for navigation" by Jason A. Etheredge, Sandra M. Perez, Orley R. Taylor, and Rudolf Jander, which appeared in number 24, November 23, 1999, of Proc. Natl. Acad. Sci. USA (96, 13845–13846), the authors note the following. "The positive response to magnetic fields in two experiments cannot be repeated. Further experiments show the false positives in these tests result from a positive taxis by the butterflies to the light reflected off the clothing of the observers. We therefore retract our report. We regret the inconvenience that publication of this study may have caused." 原論文刊載於

Fall migratory monarch butterflies, tested for their directional responses to magnetic cues under three conditions, amagnetic, normal, and reversed magnetic fields, showed three distinct patterns. In the absence of a magnetic field, monarchs lacked directionality as a group. In the normal magnetic field, monarchs oriented to the southwest with a group pattern typical for migrants. When the horizontal component of the magnetic field was reversed, the butterflies oriented to the northeast. In contrast, nonmigratory monarchs lacked directionality in the normal magnetic field. The results are a direct demonstration of magnetic compass orientation in migratory insects.
