Biology of Elaeidobius kamerunicus in the lowland and highland on North Sumatra, Indonesia

Abstract Due to limited planted areas, the oil palm was planted in the highland and showed low productivity, which could be caused by changes in the Elaeidobius kamerunicus biology, activities, and population as the primary pollinator.

Summary:Abstract Due to limited planted areas, the oil palm was planted in the highland and showed low productivity, which could be caused by changes in the Elaeidobius kamerunicus biology, activities, and population as the primary pollinator. This research aimed to gain the E. kamerunicus biology information on lowlands and highlands. This observation measured the egg, larvae, pupae, and adult. The results showed the eggs’ incubation period in lowland and highland up to 1.01±0.02 and 2.50±0.05 days, respectively. The head capsule diameter of first, second, and third instars larvae was not significantly different in lowland and highland. The lifespan of male E. kamerunicus adults was longer than females in the lowland, reach to 52.53 ± 5.82 and 37.87 ± 4.79 days, respectively. While in the highland, the female life span was more prolonged than males, reaching 10.78 ± 2.36 and 15.72 ± 3.83 days, respectively. The life cycle of E. kamerunicus was 12.25 ± 0.51 days in the lowland and 29.5 ± 8.58 days in the highland. The average eggs number laid during life was about 197.97 in the lowland, while in the highland, approximately 20.36 eggs were laid during life. Abiotic factors such as temperature, humidity, wind speed, and light intensity affect the weevil’s biology and ecology.
