台灣三月始灰象 (Sympiezomias cribricollis Kono)(鞘翅目：象鼻屬科) 之鑑定、生態與防治方法之初步研究

台灣三月始灰象 (Sympiezomias cribricollis) 為河野廣道 (Hiromichi Kono) 於1930年所定名。在過去兩年間，台灣至少已有七個縣的柑橘屬植物，隨著本種象甲族群的陡增而受到損害。其成蟲期至少可取食23種植物，其中包含數種具經濟重要性的作物，如芸香科作物與園藝作物。局部地區更因受害嚴重，致使本種象甲躍居為當地柑橘屬植物之主要害蟲。台灣因缺乏象甲之系統分類學之生態學資料，化學防治花費高但不具成效，致使防治管理不容易。有鑑於此，本研究除提供本種象甲之診斷圖片與生態資料，並據此進而提出有效的害蟲防治與管理策略。 The species Sympiezomias cribricollis was named by Hiromichi Kono in 1930. The population density of the species injurious to Citrus spp. has increased during the past 2 years at least in seven counties of Taiwan. The adult stage of this species is associated with at least 23 plant species including several important economic crops in Taiwan such as citrus and horticultural plants. Due to the serious damage it causes, it has become a primary pest in several areas. This fact, associated with the scarce systematic knowledge of weevils of Taiwan, as well as a lack of ecological information, make control management difficult, as current chemical controls are expensive and not very effective. The purpose of this paper is to provide diagnostic photographs and ecological information on S. cribricollis which is harmful to citrus in Taiwan, and to contribute to more-effective strategies for the control and management of this weevil.
