Harmful Effects of Alder leaf beetle

Agelastica alni

A species of Agelastica

Alder leaf beetle poses risks to forestry by chewing plant tissues, affecting photosynthesis and potentially causing tree death. Dense populations can stress trees, hinder growth, and impact forest ecosystems. The severity ranges from mild defoliation to significant leaf loss, with implications for timber quality and ecosystem health.

Damage Level

Mild to Severe

The forestry pest alder leaf beetle inflicts damage during its adult and larval stages by chewing plant tissues, primarily leaves. With no specific host preference, it can cause damage ranging from mild to severe. A limited population results in minor defoliation, while a substantial increase can lead to significant leaf loss, impacting photosynthesis and potentially leading to tree death, which may also affect timber quality and forest ecosystems.

Damage Level

Mild to Severe

When alder leaf beetle infests alder trees at the larval stage, it feeds on the leaves, leading to defoliation that can range from mild to severe. Sparse pest populations may only cause cosmetic damage, whereas dense infestations can stress the trees, possibly hindering growth and reducing overall plant health. Although alders are not primary agricultural crops, severe leaf loss can impact ecosystems and human appreciation of these trees.
