"Prey-prey" relationship has been formed since the time when there was a diversity of living things in nature. Various living organisms have been identified that feed on plants along with their pests and spread certain diseases, and the amount of phytophages is limited due to these natural pests. The cabbage butterfly is one of the common pests known to everyone, and it is distinguished by its high density in areas where cabbage is grown and where there are wild cabbages. Until now, this species is important as a pest of cabbage, but during the next decades, it was observed that it developed and caused certain damage in other cruciferous plants. Cabbage butterfly in the imago state feeds on plant nectar and does not harm plants, but their caterpillars have a gnawing mouth apparatus and cause severe damage.
