The pollination of the oil palm is assured mainly by the insects. The most effective are Elaeidobius kamerunicus and Elaeidobius plagiatus. Declining populations of pollinating insects in the palm oil plantation is often the cause of the low yields observed in the production of seeds. The study of the biology of these beetles has been conducted in the laboratory (27.43 ± 0.74 ° C and 75.16 ± 2.54 HR). The average of life expectancy was of 32.02 ± 12.43 days for Elaeidobius plagiatus and 59.18 ± 8.53 days for Elaeidobius kamerunicus. The total cycle time was 10.27 ± 0.34 and 8.38 ± 0.12 days respectively for E. kamerunicus and E. plagiatus. The number of eggs laid by female is of 57.64 ± 8.29 eggs for E. kamerunicus against 29.56 ± .29 for E. plagiatus.
