An Jin cruelly separated two insects in the middle of fervent copulation. Taking them in hand, she observed the sexual characteristics of each.
After identifying their features, she caught several female insects and squeezed out a few drops of the liquid secreted from their tails. This liquid was rich in sex pheromones that attracted males to mate.
She then loaded it into a palm-sized Odor Simulator and set the concentration to ten times the normal level.
Then, she tossed the Odor Simulator somewhere random.
She bought some flypaper from her space and placed it around the area. When An Jin came to check a few days later, she found the sticky boards were covered with a dense layer of insects.
Only female insects remained in the fields.
With no males to mate with, these females couldn't reproduce. They would die soon after their mating season ended.
This not only solved this year's pest problem but also prevented infestations for the next few years.
