Hatching Characteristics and Ecological Control Effect of the Citrus Bitter Orange Borer (Agrilus auriventris)
Abstract：To address the increasing damage caused by the citrus bitter orange borer (Agrilus auriventris) in old citrus orchards, a systematic monitoring of the insect's hatching dynamics and developmental process was conducted from 2019 to 2020 in Yiling District, Yichang City, using methods such as mesh net layer wrapping and splitting the trunk for dissection. The results showed that the adult emergence peak began in mid-May and lasted about 15 days, with 78.3% of individuals emerging from 15–25 cm above the base of the tree trunk. The larval stage lasted nearly 11 months, with the pupation peak occurring in mid-to-late April to early May. Based on these findings, an integrated control system combining ecological regulation, precise pesticide application, and old orchard reconstruction was established. Application in the demonstration area from 2020 to 2024 showed a 25% reduction in control costs, an 83% decrease in pest density, and a dead tree rate controlled below 0.8%. This study provides technical support for regional green pest control.
