The ability of a strip crop of sorghum to serve as a trap crop for the corn earworm in cotton was investigated in Mystic, GA in 2000. A strip of sorghum, 8 rows by 400 feet, was planted in the center of a 2.4 acre cotton plot which was located at one end of a cotton field. Corn earworm populations were monitored in the sorghum strip, in cotton adjacent to the sorghum, and in cotton in a control plot located at the other end of the cotton field. The mean number of corn earworm eggs/acre was higher in the grain sorghum than in the cotton. These results demonstrated that the corn earworm was more attracted to sorghum than cotton, and thus grain sorghum was an effective trap crop for the corn earworm in cotton. Total real mortality (r _x) of the corn earworm in sorghum was very high, and so the sorghum trapped the pest insect without becoming a source of the insect in cotton.
