Abstract

The moth peaks of Helicoverpa armigera (Hubner) are obvious under double-wave trapping light,and coincided with the egg peaks in cotton fields,so it could reflect the real situation of this pest. In the black light,those moth peaks of any generations are either not observed,or observed later than the corresponding egg peaks. In comparison with the area without trapping light,the total eggs of hundred plants of the 3rd-5th generation are decreased by 79.08%, 88. 28% and 75. 45% in the whole area,the area within a radius of 100m and the area within a radius of 150m around trapping light,respectively.
