Discover how to protect your trees and control infestations to safeguard your citrus orchards and landscapes.


Identification of Citrus Longhorned Beetles

Citrus Longhorned Beetles belong to the family Cerambycidae and the genus Anoplophora. They are giant beetles characterized by their elongated bodies and long antennae. Here are key features to help identify Citrus Longhorned Beetles:

  • Size: Adult beetles can range from 1 to 2 inches long.
  • Coloration: Their bodies are typically black or dark brown with irregular white or yellow spots.
  • Antennae: Long antennae extend well beyond their bodies and may have alternating black-and-white or black-and-yellow segments.

Latin Name

The scientific name of the Citrus Longhorned Beetle is Anoplophora chinensis. The genus name “Anoplophora” is derived from the Greek words “anoplos,” meaning unarmed, and “phoros,” meaning bearer. This refers to the lack of spines or thorns on the beetle’s body. The species name “chinensis” indicates it is native to China.

Behavior and Damage

Citrus Longhorned Beetles are known for their destructive feeding habits. They primarily attack various woody plants, including citrus, apple, pear, and other hardwood species. The larvae of these beetles bore into the trunks, branches, and twigs of host trees, causing significant damage to the tree’s vascular system. This can lead to the infested trees’ wilting, dieback, and even death of the infested trees.

Extermination Techniques for Citrus Longhorned Beetles

Effective control of Citrus Longhorned Beetles requires a comprehensive approach that combines detection, monitoring, and targeted treatments. Here are common extermination techniques:

  1. Tree inspection: Regularly inspect citrus and other susceptible trees for signs of beetle infestation, like exit holes, sawdust-like frass, or wilting branches.
  2. Tree removal and destruction: Infested trees may need to be removed and destroyed to prevent the spread of beetles to healthy trees.
  3. Chemical treatments: Insecticides labeled for Citrus Longhorned Beetle control can be applied to the trunks and branches of infested trees, following manufacturer instructions and safety guidelines.
  4. Trapping and monitoring: Use pheromone traps to attract and capture adult beetles for monitoring purposes. This helps assess the population and guide targeted treatments.
  5. Tree health maintenance: Maintain tree health through proper irrigation, fertilization, and pruning practices, as healthy trees are more resistant to infestations.
