摘    要:报道红棕象甲Rhynchophorus ferrugineus Fab.成虫交配、产卵行为,描述在交配和产卵过程中发生的多种行为。红棕象甲整日均可见其交配行为,但在暗光周期开始0.5h左右明显有一个交配高峰期。其交配持续时间、交配几率不受虫体大小的影响。在无外界因子干扰的条件下,交配持续时间均可达1min。红棕象甲卵为单产,一处1粒,主要是通过口喙蛀孔辅助完成;观察红棕象甲幼虫、蛹的行为,例如取食、争斗、蜕皮、做茧等行为。且随着低龄幼虫向高龄幼虫的过渡,幼虫的取食和钻蛀行为从棕榈植物中心向外围扩散。通过摇动或震动茧后红棕象甲在其中表现的行为,并结合茧的颜色和质地可准确判断茧中存在的3种虫态。

关 键 词:红棕象甲  交配  产卵  行为

Abstract:The mating and oviposition behavior of red palm weevil, Rhynchophorus ferrugineus Fab. was observed in laboratory. Mating behavior may be observed in the whole day, but a peak of mating occurred in the half hour of the beginning of the dark period. Moreover, mating duration and probability were not influenced by body size. Without external interference, mating duration may be more than 1 minute. After the copulation, females bored a hole, and laid one egg each hole. In addition, larval and pupal behaviors were also studied, such as feeding, fighting, exuviating and cocooning. With the development from young to old larvae, the feeding and drilling were from centre to periphery of palms. Through the behavior of red palm weevil in shaking of cocoon and combination with observation of the color and texture of the cocoon, the three stages of cocoon could be distinguished.
Keywords:Rhynchophorus ferrugineus  mating  ovipositing  behavior
