摘要

亞洲棕櫚象鼻蟲（Rhabdoscelus lineatocollis（Heller）（Coleoptera：Rhynchophoridae））為台灣新紀錄之害蟲，於民國86年10月間首次於彰化縣田尾鄉被發現，其幼蟲危害棕櫚科植物莖幹，而使植株產量減少，嚴重時會造成實生苗或幼苗的死亡。高屏地區於民國87年2月發現大面積之黃椰子受害，近年來更延伸至檳榔植株，但未發現危害其他作物。該蟲於實驗室內22℃－30℃不同溫度處理，相對濕度85%之環境下，利用鮮食甘蔗飼養結果顯示其卵期為3.53～10.44天、幼蟲期為37.48～71.42天、蛹期為8.24～19.23天。利用紅蘿蔔作為產卵基質，其後以甘蔗片為飼養材料，於25℃室內觀察其成蟲壽命，結果顯示其壽命為142 ± 217天左右。

The Asiatic plam weevil, Rhabdoscelus lineatocollis, is a newly discovered pest in Taiwan. Its larvae damage stems, reduce yield or kill seedlings and young palms. In Kao-Ping areas, in February 1998, large acreage of yellow palms was found damaged by this pest. Recently, damage incidences betlenut were also reported on the betlenut palm not or on other crops.The results of rearing the Asiatic palm weevil on fresh, edible sugarcane under the laboratory condition showed that the range of the duration for each stage of its development at 22-30℃ was 3.53∼10.44 days for the egg stage, 37.48∼71.42 days for the larval stage, and 8.24∼19.23 days for the pupal stage. The adult longevity was 142 ± 217 days at 25℃.
