Larvae feed on the roots of the emerging plants, which causes the most damage since the young plants are more vulnerable. [1] In the adult stage the beetles cause damage by eating the flowers, leaves, stems, and fruits of the plant [1] The beetles can also spread diseases such as bacterial wilt and mosaic virus. [2]
