Abstract
Sweet potato (Ipomoea batatas L.) is one of the agricultural commodities that serves as an alternative food source. Uret (white grub) is one of the major pests that attack sweet potato plants and can reduce the quality of their external appearance. This study aimed to identify the species of uret pest that attack six sweet potato cultivars. The research was conducted from July to November 2024 on a farmer’s field. The method used was an experimental method with a Randomized Complete Block Design (RCBD), consisting of six cultivars as treatments, each repeated four times, resulting in 24 experimental units. The treatments were K1 (Lato-lato), K2 (Cilembu), K3 (Tailand), K4 (Kentang), K5 (Ase), and K6 (Ungu). The results showed that two uret species were found attacking all sweet potato cultivars. These uret species were Phyllophaga sp. and Leucopholis sp., both belonging to the family Scarabaeidae, order Coleoptera. The Ungu cultivar showed the lowest average population of 8.5 larvae, while the Ase cultivar showed the highest average population of 16 larvae. The uret pest attacks only reduced the external appearance quality of the sweet potatoes, so the tubers were still suitable for consumption.
