What is the Japanese Beetle?
The Japanese beetle, a highly destructive and invasive plant pest, feeds on the leaves of plants and trees. Additionally, it targets over 300 types of ornamental and agricultural plants, resulting in defoliation. First identified in the U.S. in 1916, these beetles have since spread east of the Mississippi River and have partially infested some western states. Consequently, they pose a significant threat to plant life, making preventive efforts essential. Emerging from the ground between May and June, these beetles have a lifespan of approximately 30 to 50 days, with the majority of their feeding completed by mid to late August.
What does it look like?
The Adult Japanese Beetles measure approximately 3/8 to 1/2 inch in length. Moreover, they exhibit a distinctive appearance with a shiny, metallic green body and copper-brown or bronze wing covers. To distinguish them from similar-looking beetles, it is important to note the presence of five small, white tufts of hair beneath the wing covers, along with an additional tuft at the end of the abdomen.
Symptoms to look for:
- Defoliation: They feed on the leaves of plants, resulting in skeletonized or partially eaten foliage. If you notice extensive leaf damage or the sudden disappearance of leaves, it could be a sign of infestation.
- Wilting or browning: Their heavy feeding can weaken plants and cause them to wilt or turn brown prematurely. If you observe sudden wilting or browning of your plants, it could be a result of their feeding.
- Presence of beetles: Directly spotting adult Japanese beetles on trees is a clear indication of an infestation. Shiny green beetles with copper-brown wing covers are likely causing the damage.
How to mitigate the Japanese Beetle:
To address Japanese beetle infestation, it is advisable to contact a local professional arborist like L&T Tree Services. They evaluate, diagnose, and create a customized treatment plan, apply pesticides safely, improve plant health, and educate homeowners on prevention. It is crucial to act promptly at the first sign of infection. Therefore, take immediate action at the first sign of infection and have confidence in the knowledge and skills of your professional arborists to ensure effective treatment and the long-term protection of your plants and trees.
