Rock and Roll Ain’t Noise Pollution, or Is it?

Mississippi State University Biology Professor Brandon Barton decided to test the hypothesis by putting ladybugs in soybeans infested with aphids, then subjecting a sample group with various sounds. After 15 hours or so, the ladybugs exposed to hard rock, AC/DC, city sounds, and aircraft noise, greatly reduced the number of aphids they ate. Ladybugs not exposed to loud sounds, consumed virtually all of the aphids. Both aphids and soybeans, however, appeared not to be affected by loud sounds.
