Abstract

The orange tortrix on apples in California usually has been controlled satisfactorily by the use of TDE in the codling moth schedule of treatments. However, the recent increase in cases of codling moth resistance to TDE—and to DDT—has caused some growers to change to other insecticides, although little is known about the effectiveness of the substitute compounds against orange tortrix.
