摘　　要：本文研究了油棕最有效的授粉昆虫油棕象甲Elaeidobius kamerunicus Faust的成虫交配、产卵行为,并对交配和产卵过程中发生的多种行为进行了描述。结果表明:油棕象甲一次完整的交配过程可以划分为交配前、交配、交配后三个阶段,在交配过程中雄虫会发生多次插入授精。油棕象甲一次完整的交配过程平均需要437.33s,其中授精前的抱对时间平均为22.33s,交配过程中每次授精插入时间平均为5.33s,配后保护时间平均为85.67s。油棕象甲的卵为单产,在一朵油棕雄花内一般只产1粒卵,产卵前雌虫用喙在雄花上制造产卵孔,同时用触角辅助完成。观察油棕象甲幼虫取食和蜕皮等行为。Elaeidobius kamerunicus Faust was identified as the most efficient insect pollinator of oil palm. The mating and oviposition behavior of E. kamerunicus was observed in the laboratory. The results showed that a complete mating of E. kamerunicus involved three stages： before mating, mating and after mating. There were many ejaculations in the whole mating process. The average lasting time for one copulation of E. kamerunicus was 437.33 s, the time for pair - bonding before ejaculation was 22. 33 s with each ejaculation of 5.33 s, and the time of post - copulatory guarding was 85.67 s. After the copulation, females bored a hole, and laid one egg each hole. In addition, larval behaviors was also studied, such as feeding and molting.
