Elaeidobius kamerunicus is the main insect pollinator for oil palm (Elaeis guineensis) worldwide. One of the main reasons E. kamerunicus attracted to oil palm inflorescences is estragole, a volatile organic compound released by the oil palm inflorescences during anthesis stage. However, the amount of estragole released from the oil palm inflorescence is varied due to the influence of abiotic and biotic factors and is seen to have an impact on E. kamerunicus pollination activity on the oil palm. To evaluate the responses of E. kamerunicus, different types (wild and reared) and sex (male and female) of E. kamerunicus were exposed to different concentrations of commercial estragole using a four-arm olfactometer. Results showed that E. kamerunicus significantly preferred one hundred ppm of estragole compared to other concentrations. However, the response of E. kamerunicus was significantly decreased after the concentration value. The result of this study can be a good platform for future references since the estragole compound plays a significant role in oil palms flower pollination by E. kamerunicus.
