Which stage in the life cycle of Asiatic Garden beetles are most likely to be damaging?

The larvae stage of the Asiatic Garden beetle is typically the most damaging to turf and garden plants. During this phase, the larvae are below ground and feed on the roots of plants, which can lead to significant damage and even plant death. Their feeding habits disrupt the plant's ability to absorb water and nutrients, resulting in poor growth and overall plant health.

In contrast, while adults can cause damage by feeding on the plant foliage, the impact is generally less severe compared to that of the larvae. Eggs and pupae stages do not actively feed, and hence do not contribute to the damage during those stages. Understanding the life cycle and the specific points at which these pests cause harm is crucial for effective pest management strategies.
