Research progress in monitoring and green control of Anoplophora glabripennis Motschulsky (Coleoptera: Cerambycidae)

The Asian longhorned beetle, Anoplophora glabripennis (Coleoptera: Cerambycidae), is a widely distributed and highly destructive wood-boring pest in China, posing a significant biological threat to the "Three-North Shelterbelt Program". Due to its cryptic lifestyle, controlling this pest is challenging, and traditional chemical control methods have limited efficacy while often causing environmental pollution. In recent years, significant progress has been made in researches on monitoring and green control technologies for A. glabripennis. This paper reviews recent advances in monitoring techniques, frontier achievements in green control technologies centered on biological control, and other innovative control concepts. In terms of monitoring, a multi-dimensional technical system has been established, including quarantine inspection, manual and visual monitoring, trapping techniques, acoustic detection, and molecular biology identification, significantly improving the accuracy and timeliness of pest detection. For control, biological control serves as the core strategy, with extensive application of natural enemies such as Dastarcus helophoroides, parasitic wasps like Sclerodermus spp., and Pyemotes mites. Combined with ecological regulation measures such as mixed-species afforestation and the deployment of trap trees, effective and sustainable suppression of A. glabripennis populations has been achieved. Although existing technologies have demonstrated good results in practical applications and are gradually being promoted, challenges remain, such as the susceptibility of monitoring methods to environmental interference and the inconsistent field performance of natural enemies. These issues require further research and optimization. This paper also summarizes the limitations of current technologies and provides prospects for future research directions, aiming to offer references for the sustainable management of A. glabripennis.
