Pests of mandarin orange and its importance in Sikkim, India
Mandarin orange (Citrus reticulata Blanco) is a major cash crop in Sikkim and in this paper the pests of mandarin orange obtained through inputs from farmers of Sikkim are documented with symptoms of pest attack and prevalence of important pests. Citrus long horned beetle (Anoplophora versteegi) was the most destructive pest followed by stem borer Japanese beetle (Popillia japonica) and four Hemipterans (Planococcus citri, Toxoptera aurantii, Toxoptera citricidas and Diaphorina citri) collectively called laikira. These pests were common across all sites as compared to other pests. This work can serve as a baseline for future researchers as well as government agencies to engage in management of these pests.
