WHO CAUSES IT?
Copturus aguacatae is a beetle belonging to the family Curculionidae. This insect, commonly known as a branch borer, is a small, dark beetle whose main activity focuses on the branches and trunks of avocado trees. The adults emerge during the hot season and look for trees to lay their eggs. Females pierce the bark of the tree to lay their eggs in galleries that they excavate in the wood. The larvae hatch and begin feeding on the internal tissue of the tree, creating tunnels that interfere with the flow of nutrients and water. After completing their larval development, the larvae pupate within the wood and emerge as adults to repeat the cycle.

SYMPTOMS
The disease caused by the branch borer in avocado is manifested through the structural and physiological damage caused by the beetle larvae when feeding on the wood of the tree. This damage can result in significant weakening of branches and, in severe cases, death of the tree. The main symptoms include wilting of leaves, dieback of branches, presence of sawdust or exudates on the bark, and reduced fruit production. Infestation may also predispose the tree to secondary infections by opportunistic pathogens.
• Wilting of leaves
• Branch dieback
• Presence of sawdust or exudates on the bark
• Reduction in fruit production
TEMPERATURE AND HUMIDITY
22ºC - 28ºC
65% - 75%
TRANSMISSION PATHS

Recommendations
• Regularly monitor avocado trees for signs of infestation, especially during the hot season.
• Carry out sanitary pruning to eliminate and destroy infested branches, preventing the spread of the beetle.
• Use pheromone traps to capture adults and reduce the population.
• Apply systemic insecticides to infested trees to reach and eliminate larvae within the wood.
• Maintain good overall tree health through proper watering and fertilization practices, which helps increase the tree's resistance to infestations.
• Avoid introducing infested plant material to unaffected areas to prevent the spread of the pest.
• Promote the diversity of the agricultural landscape to reduce the density of susceptible hosts.
