Tomato plant (Solanum lycopersicum L.) is a type of horticultural plant that has many benefits for human health and is widely developed in Indonesia, especially in Bali. Pests of tomato plants are Spodoptera litura Fab. (Lepidoptera: Noctuidae). This study aims to calculate the total population and the percentage of S. litura pest attacks on tomato plants in Sekaan Village, Kintamani District, Bangli Regency. The research was conducted from July to September 2022 in Sekaan Village, Kintamani District, Bangli Regency, Bali. This research was conducted using the direct survey method. Sampling was carried out by purposive sampling using the diagonal sampling method with 10 sample points and 5 plant clusters were taken at each sampling point so that a total of 50 plant families were observed. The variables observed were the number of populations and the percentage of pest attack by S. litura. The data obtained were analyzed and presented in the form of tables and graphs. The results showed that S. litura was found on tomato plants in farmers' fields. Pests began to be found at 14 DAP (Day After Planting) with an average of 2 individuals and the highest population was found at 70 DAP with an average of 29 individuals on tomato plants. The results of the analysis show that the high percentage of attacks occurring at 70 DAP is 40%. In general, the high number of pest populations affects the high percentage of S. litura attacks.
