2.25 Lepropus sp.

2.25.1 Occurrence and Damage

Lepropus sp. (Coleoptera: Curculionidae: Brachyderinae: Tanymecini) is mainly distributed in southwest Yunnan province in China (Huang and Li 2014). In addition to sugarcane, Lepropus sp. also damages soybean, peanut, rice, wheat, sweet potato, maize, tea tree, mulberry tree, coffee tree, rubber tree, banyan tree, peach, plum, banana, citrus, and sagebrush (Huang and Li 2014). In the field, sugarcane is often damaged by the combined occurrence of Lepropus sp., Hypomeces squamosus Fabricius, and Polyclaeis sp. Among them, the population of Lepropus sp. accounts for 20% of the insects (Huang and Li 2011). In recent years, Lepropus sp. outbreak has occurred frequently in sugarcane-planting areas in Guangxi and southwestern Yunnan, such as Menglian, Menghai, and Mengzi, and hundreds of hectares of sugarcane have been damaged (Huang et al. 1999b; Huang and Li 2011). In severely damaged fields, there are two or three Lepropus sp. on each sugarcane (Huang et al. 1999b; Huang and Li 2011). A large number of sugarcane leaves are eaten by Lepropus sp., leaving only the leaf veins, which seriously affects the growth of sugarcane and causes significant production losses (Huang et al. 1999b; Huang and Li 2011).
