Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Indonesia is the world's largest producer of crude palm oil (CPO), reaching approximately 54 million tons in 2024. Pollination is a crucial factor in the success of palm oil production, with the main pollinating insect, Elaeidobius kamerunicus, playing a highly dominant role in fruit formation. However, the population of these insects is highly influenced by environmental conditions, particularly the difference between the rainy and dry seasons. This study aimed to determine the number of E. kamerunicus during the rainy and dry seasons. Observations were made by collecting samples of male and female flowers at several randomly selected points. The research results indicate a significant variation in the number of E. kamerunicus individuals between the two seasons. During the rainy season, the population tends to be lower due to high humidity and rainfall, which can affect insect flight activity and survival. Conversely, during the dry season, the population is higher because the relatively dry environmental conditions support pollination activity and the continuation of the insect's life cycle. Additionally, differences in population size are also evident in male and female flowers, with male flowers tending to be more heavily populated by insects than female flowers. This population variation demonstrates a close relationship between flower availability, climatic conditions, and the life dynamics of E. kamerunicus. This finding confirms that seasonal factors play an important role in determining the effectiveness of natural pollination in smallholder oil palm plantations.
