Sweet potato is a strategic food crop and the fourth-largest source of carbohydrates after rice, corn, and cassava. The production of sweet potatoes from 2016 to 2020 has decreased by 34.77%. One of the challenges faced is pest and disease infestation. One significant pest affecting sweet potato plants is the Cylas formicarius weevil. This research aims to gather information on the level of infestation of the sweet potato weevil in Cilembu sweet potato plantations in Sumedang Regency. The study was conducted from February to June 2022. Observations were made on 15 farmer fields in three designated villages. Observations on the age structure and population density of C. formicarius in each farmer's field were conducted by taking three tubers showing severe infestation symptoms. Observation data were tabulated in MS Excel 2013, and ANOVA tests were conducted using the SAS application. The highest population of C. formicarius was found in Cilopang Village, with a larval population of 228, pupal population of 167, and adult population of 199. The highest infestation rate of C. formicarius reached 78,94% in Cilopang Village.
