TINGKAT SERANGAN DAN POPULASI KUMBANG TANDUK PADA PERKEBUNAN KELAPA SAWIT (Elaeis guineensis Jacq.) DI KABUPATEN OGAN ILIR
Oil palm (Elaeis guinensis Jacq.) is a major plantation commodity because it has high economic value, high productivity, and a strategic role in supporting national industry and the economy. The sustainability of palm oil production is greatly influenced by the health of the plants, which is threatened by insect pest attacks. One of the important pests on oil palm plants is the beetle, which attacks plant tissues and has the potential to reduce productivity. This research aims to examine the presence of rhinoceros beetles, the level of attack, and the environmental factors that influence their development in oil palm plantations in Ogan Ilir Regency. The research was conducted thru a field survey using purposive sampling in areas indicated to be experiencing pest attacks. Data collection was carried out using Ferotrap and Orynettrap traps, accompanied by observations of the surrounding environmental conditions of the plants. The data obtained were used to evaluate differences in population and horn beetle attack rates between the study locations. The research findings indicate that the rhinoceros beetles found consist of Oryctes and Xylotrupes Population levels and horn beetle attacks tend to be higher in locations with favorable environmental conditions, particularly those related to organic matter accumulation, soil moisture, and drainage systems. Additionally, Ferotrap showed better effectiveness compared to Orynettrap in attracting imago of rhinoceros beetles.
