Abstract The pink sugarcane mealybug, Saccharicoccus sacchari is one of the important pests of sugarcane in China. Infestation levels of S. sacchari on 8 sugarcane varieties were investigated at sugarcane regional trial stations in 2018-2019 in Guangxi Province, China. Damage levels were assessed by counting the number of mealybugs per stalk and calculating the percentage of stalk damage. The results showed that there were significant differences in population density and damaged level of S. sacchari on new planted sugarcane varieties at Laibin sugarcane regional experiment stations in 2018, and population density on ratoon sugarcane varieties at Laibin and Chongzuo (Longzhou) sugarcane regional… Login to continue
