Today, chrysanthemum is a flower that is favored by many people because of their variety and color, and has been used more and more popularly by people. Chrysanthemums have also been grown in many regions of the country, in order to meet the growing market demand.

As a result, many types of pests have arisen, with increasingly high and dangerous levels.
