Twig Pruner Beetles: A Common Problem for Trees
Twig pruner beetles are small insects that can cause damage to trees. They are members of the longhorn beetle family, and they get their name from their long antennae. Twig pruner beetle larvae are the ones that actually damage trees. They feed on the inside of twigs, causing them to become hollow. Once the twigs are hollowed out, they are easily broken off by the wind and fall to the ground.
Identifying Twig Pruner Beetles
Adult twig pruner beetles are difficult to find, but their larvae are easy to identify. If you see fallen twigs around the base of a tree, pick them up and look closely at the cut ends. If you see an oval chamber packed with sawdust-like material, it is likely that the twig has been damaged by twig pruner beetle larvae.
Twig Pruner Beetle Damage
Twig pruner beetle damage is not typically severe. The loss of a few twigs does not usually cause any permanent harm to the tree. However, if the infestation is severe, it can cause the tree to look ragged and unkempt.
Twig Pruner Beetle Control
The best way to control twig pruner beetles is to remove and destroy the fallen twigs that contain the larvae. This will interrupt the beetle’s life cycle and prevent them from reproducing. You can also encourage natural enemies of twig pruner beetles, such as birds and parasitic wasps, to help control the population.
How to Identify Twig Pruner Beetles
- Look for fallen twigs around the base of trees.
- Examine the cut ends of the twigs for oval chambers packed with sawdust-like material.
- If you find these chambers, it is likely that the twigs have been damaged by twig pruner beetle larvae.
What Does Twig Pruner Beetle Damage Look Like?
