1. A method for simultaneously controlling a pink bollworm and a species selected from an American bollworm and its family, the method 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 29 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 and Z-11-hexadecenal, which are sex pheromone substances of the pink bollworm and the species selected from an American bollworm and its family, respectively, in the field during a period of from 2 days to 15 days before a predicted emergence date of the next-generation adult pink bollworms, the predicted emergence date being derived from accumulated degree days, to release the Z,Z/Z,E-7,11-hexadecadienyl acetate and the Z-11-hexadecenal into the field.
