What parts of a plant do adult and larvae beetles typically damage?

Adult and larvae beetles typically damage plants through boring and chewing. This method of feeding can significantly harm the plant's overall health. Adult beetles usually feed on the foliage, causing defoliation which impairs the plant's ability to photosynthesize. Larvae may feed on underground plant parts, including stems and roots, depending on the species. This behavior not only damages the plant physically but can also make it vulnerable to diseases and other pests, leading to reduced yield and vitality.

The other options, while they mention specific plant parts, do not encompass the full range of damage methods associated with beetles. For instance, roots and ovaries may be damaged by some pests, but this does not apply universally to all beetles. Flowers and seeds, fruits, and tubers are less commonly targeted as feeding sources in comparison to the broad chewing and boring actions characteristic of most beetles' life stages. Therefore, the general description of the damage method through chewing and boring is the most accurate in representing the behavior of adult and larvae beetles.
