1. A method for controlling a pink bollworm comprising steps of:
planting a cotton seedling in a field during a period of from 21 days to 41 days after an emergence date of the first-generation adult pink bollworm, or during a period of from 1 day to 21 days after an emergence date of the second or later generation adult pink bollworm; and
installing a sustained release pheromone preparation comprising Z,Z/Z,E-7,11-hexadecadienyl acetate, which is a sex pheromone substance of the pink bollworm, in the field during a period of from 2 days to 15 days before a predicted emergence date of the next-generation adult pink bollworm, the predicted emergence date being derived from accumulated degree dates, to release the Z,Z/Z,E-7,11-hexadecadienyl acetate into the field.
