City longhorn beetle (Aeolesthes sarta): A review of the species, its distribution, ecology, damage, prevention and control

Abstract

The city longhorn beetle (Aeolesthes sarta) (CLB) (Coleoptera – Cerambycidae) is a polyphagous invasive pest of both healthy and suppressed broadleaved trees in central Asia. CLB causes a great degree of damage in the countries of its origin. To understand this pest in a better way, a detailed review study has been conducted to gather all the valuable information related to the CLB. This review study covers the main aspects of the CLB, its morphology, ecology, distribution, damage, and control measures. The life span of the CLB is two years. It is mainly distributed in the central Asian countries and preferably damages broadleaved tree species, especially Juglans regia, Populus alba, P. euphratica, Acer spp, Salix alba, S. babylonica, Malus pumila, M. sylvestris, Platanus orientalis and Ulmus spp. Effective control and management practices include cutting, removing + burning of infested trees, cultivating high resilient tree species, use of biocontrol agents (i.e. fungus), and use of aluminium phosphide as a pesticide to significantly help control the CLB population. A CLB invasion in a new favourable habitat could impose a serious threat to broadleaf forests and plantations. Therefore, the keen monitoring and surveying of woodland management techniques are recommended. The strict monitoring and inspection of traded wood material at airports and seaports are highly recommended. There is a need to conduct multiple research studies to profoundly understand the CLB phenology, ecology, transportation mode, and damage severity to bridge the gap.
