Most Common Glacier Eucalyptus Plant Pests:
Identification and Treatment Guide

The Glacier Eucalyptus plant, also known as Eucalyptus crenulata, is a popular ornamental plant known for its distinct silvery-gray foliage and compact growth habit. However, like all plants, it is susceptible to pests that can cause significant damage if left untreated. In this article, we will discuss the most common Glacier Eucalyptus plant pests, how to identify them, and the best treatment options.

Common Glacier Eucalyptus Plant Pests

1. Eucalyptus Leaf Beetle

The Eucalyptus Leaf Beetle is a notorious pest that feeds on the leaves of eucalyptus plants. The adult beetle is a bronze-colored beetle that measures about 5mm in length. The larvae are green and have black heads. They feed on the leaves and skeletonize them, causing significant damage.

2. Red Gum Lerp Psyllid

The Red Gum Lerp Psyllid is a small insect that feeds on the sap of eucalyptus plants. They secrete a sugary substance that creates a protective covering over their bodies called lerps. The lerps look like small bumps on the leaves and stems of the plant. The psyllids feed on the sap inside the lerp and can cause defoliation if left untreated.

3. Eucalyptus Longhorned Borer

The Eucalyptus Longhorned Borer is a type of beetle that feeds on the bark of eucalyptus trees. The larvae tunnel beneath the bark, causing damage to the tree’s cambium layer, which transports nutrients and water throughout the plant. This can lead to stunted growth and eventual death if left unchecked.

4. Eucalyptus Gall Wasp

The Eucalyptus Gall Wasp is a tiny insect that lays its eggs in the stems and leaves of eucalyptus plants. The larvae hatch and feed on the plant tissue, causing galls or abnormal growths to form on the plant. These galls can weaken the plant and lead to branch dieback.

How to Identify Glacier Eucalyptus Plant Pests

To identify Glacier Eucalyptus plant pests, you will need to closely examine the leaves, stems, and trunk of the plant. Look for signs of insect activity such as chewed leaves, holes in the bark, or bumps on the leaves or stems. You may also notice wilting or yellowing leaves or stunted growth.

If you are unsure what pest is affecting your plant, you can take a sample and bring it to your local nursery or extension office for identification.

Treatment Options

The treatment options for Glacier Eucalyptus plant pests will vary depending on the type of pest and the severity of the infestation. Here are some common treatment options:

1. Insecticidal Soap

Insecticidal soap is a non-toxic option that can be used to control many types of pests including leaf beetles and psyllids. Spray the soap directly onto the affected areas of the plant, being sure to cover both sides of the leaves.

2. Neem Oil

Neem oil is a natural pesticide that can be used to control a variety of pests including leaf beetles, psyllids, and gall wasps. Mix neem oil with water according to package instructions and spray onto affected areas of the plant.

3. Systemic Insecticides

Systemic insecticides are a type of pesticide that can be absorbed into the plant’s system and kill pests from within. They are effective against longhorned borers and gall wasps. Apply the insecticide according to package instructions.

4. Manual Removal

For small infestations, manual removal of the pests may be effective. Use pruning shears to remove affected stems or leaves and dispose of them in a sealed bag.
