How do I know if my tree has Elm Leaf Beetle?

The evidence of your tree being affected by elm leaf beetle is very easy to ascertain in October to December when new foliage has appeared.

Adult elm leaf beetles cause small shot holes in the leaves ranging to 1mm in diameter then lay eggs. Upon hatching the elm leaf beetle larvae then skeletonise the leaf between the leaf veins.

WHAT DOES AN ELM LEAF BEETLE LOOK LIKE?

The adult beetle is about 6mm long and yellowish to olive green, with a black stripe along each side of the wing covers (see image left). The stripes are sometimes indistinct in the dark olive forms. The adult has black eyes and has four black spots on its thorax.

Eggs are laid in groups of up to 30 on the underside of leaves. They are pointed, orange-yellow and about 2mm long.

 

What is the best way to help my tree?

The best way to care for an Elm is to put a management plan in place. This includes treatment during the months of September and October, repeating every 2 years.

Tree Technique has extensive experience, and equipment to treat infected trees. We typically use steam injections, which through the careful use of systemic insecticides, control Elm Leaf Beetle numbers from spreading, and, in-turn improve the health of your trees.
