Remarks.

According to Easton (1992), C. annularis , or bamboo longhorn, was very common in Macau in the early 1990s, particularly during 1990 when it was suggested that it may have emerged from the numerous bamboo poles used in the scaffolding of new buildings that were being constructed next to the university campus. However, during this census the species was a rare occurrence in Macau, where adults were active in spring and summer and ranged 10-14 mm in total length and 2-3.5 mm in maximum width. Chlorophorus annularis is primarily a borer of dry bamboo species belonging to several genera, but it also attacks cultivated crops and wild plant species ( Friedman et al. 2008). Both larvae and adults have been introduced into several European, Middle East, African, American and Oceanian countries through bamboo canes and their derived products imported from south-east Asian countries, especially China ( Suma and Bella 2018).

The main larval host plants for the species include Bambusa spp., Chimonobambusa tumidissinoda , Dendrocalamus strictus , Dipterocarpus tuberculatus , Cassia fistula , Gossypium sp., Indosasa crassiflora , Phyllostachys reticulata , Saccharum officinarum , Sinocalamus spp., Vitis spp., and Zea mays ( Friedman et al. 2008; Suma and Bella 2018). Other plants utilised to a lesser extent are Albizia spp., Betula spp., Citrus spp., Derris microphylla , Liquidambar formosana , Malus sylvestris , Pyrus malus , Shorea robusta , Sinobambusa gibbosa , Spondias sp. and Tectona grandis ( Duffy 1968; Makihara et al. 2008; Yiu 2009; Lim et al. 2014; Suma and Bella 2018).
