APPARENT DDT TOLERANCE IN AN AQUATIC INSECT DISPROVED BY TEST
Published online by Cambridge University Press: 31 May 2012
Abstract
Certain mayflies and stoneflies were present in a forest stream in New Brunswick after frequent yearly sprayings with DDT. Tests showed that a stonefly, Nemoura sp., apparently the most likely insect to have developed DDT tolerance, had not done so. Presence of mayflies and stoneflies in the stream was probably because they survived spraying while in the egg stage, or recovered quickly after spraying, or both.
