Emerald ash borer

Emerald ash borer

Agrilus planipennis

A species of Agrilus, Also known as Eab

The emerald ash borer (Agrilus planipennis) has a long body with metallic green coloring. Its host plant is the green ash, and it can kill even healthy ash. These bugs can chew right through the trees, leaving a D-shaped hole behind them. The females specifically seek green ash trees, so it's rare that they will lay eggs on any other plants.

Life Cycle of Emerald ash borer
Egg The egg of emerald ash borer is laid within the bark crevices of trees. Eggs are small, oval, and yellowish. They serve as a protected stage for embryonic development, culminating in a larva.
Larva Upon hatching, the larva of emerald ash borer is legless and whitish with a distinct flattened head. It feeds voraciously, growing larger and molting several times, with clear changes in size but not color.
Pupal Emerald ash borer transforms into immobile pupae within a cocoon-like structure. During this stage, profound changes occur as tissues reorganize. The color transitions from pale to the adult's coloration, and limbs and wings form.
Adult Emerging from the pupa, the adult emerald ash borer's development is marked by the presence of wings and functional reproductive organs. The body is fully formed and hardened, and the adult is mobile, focusing on reproduction.

How Can You Attract Emerald ash borer
Since adult emerald ash borer feed on leaves, a trap with leaf volatiles or pheromones can be used as an attractant.
Rectangle
Habitat Preferences of Emerald ash borer Through Different Life Stages
Eggs of emerald ash borer are typically laid on the bark of ash trees, where the larvae bore into the wood and create galleries for development. To locate the larvae, you would inspect the trunks and branches of ash trees for D-shaped exit holes or bark splits. Pupae reside within the outer sapwood or just beneath the bark, where they transform into adults. Searching for these requires peeling back the bark or observing the area during emergence times. Adult emerald ash borer can often be found on or around ash trees as well, particularly on the leaves or bark, where they feed and mate.

When is the Best Time to Observe Emerald ash borer
Adult emerald ash borer are usually active during the daytime, especially in warm, sunny weather. For various life stages, the suitable time may differ.

What is the Best Weather to Observe Emerald ash borer
Warm and sunny weather conditions are more suitable for finding adult emerald ash borer, as they are more active during these times.

Forestry Pest

The adult emerald ash borer primarily feeds on the leaves of ash trees, while the larvae bore into the tree's inner bark, disrupting nutrient and water flow, often leading to tree death. When present in high numbers, they can decimate ash populations, affecting local ecosystems and potentially causing economic impacts.

Rectangle
Hurt Plant

The invasive emerald ash borer poses a severe threat, particularly to Ash trees. As adults and larvae, these insects bore into the bark and feed on plant tissues, disrupting nutrient and water flow, leading to canopy thinning, branch dieback, and ultimately, tree mortality.
