小蠹蟲及長小蠹蟲名錄、分布及寄主植物

在全球暖化及環境變遷下，危害林木的蠹蟲(小蠹蟲、長小蠹蟲、長蠹蟲等)在近年的重要性也相對提高。台灣長期缺乏對這些昆蟲進行研究，所以在系統分類上、生態上甚至可能造成林木危害的風險評估的認知上都相當缺乏。美國近年監測境內小蠹蟲而發現已經超過一百種外來種，也調查到一些會造成樹木死亡的蠹蟲類害蟲，尤其是會攜帶共生真菌的菌蠹蟲。其中幾種更是對農作物(酪梨)及其他林木造成危害。來自亞洲的樟楠小蠹蟲入侵美國後，在弗羅里達州造成的酪梨產業重創。而加州則有另一種入侵種--多食華小蠹蟲危害加州的酪梨產業，還對於南加州 335種樹造成危害。
本研究針對15種國外重要小蠹蟲進行風險評估。這些國際上重要的小蠹蟲經過傳入後果之風險評估及傳入可能性之風險評估，美洲及歐洲重要危害林木的小蠹蟲在風險評估下在台灣均屬於低風險性害蟲。而東南亞的兩種小蠹蟲經評估後在台灣屬於高風險性害蟲。並完成30種台灣小蠹蟲亞科及20種台灣長小蠹蟲亞科形態鑑定、分布及生態資料。

Under global warming and environmental changes, the importance of forest-damaging wood-boring beetles (including bark beetles (Scolytinae), ambrosia beetles (Platypodinae), and true powderpost beetles (Bostrichidae), etc.) has relatively increased in recent years. Taiwan has long lacked targeted research on these insects, leading to substantial gaps in knowledge regarding their systematic classification, ecology, and even risk assessment of potential forest damage caused by them. In recent years, the United States has conducted monitoring of bark beetles within its territory and identified over 100 invasive species, as well as several beetle pests that cause tree mortality, particularly ambrosia beetles that carry symbiotic fungi. Several of these species have caused damage to agricultural crops (avocado) and other forest trees. After invading the United States, the camphor and laurel bark beetle native to Asia caused severe losses to the avocado industry in Florida. In California, another invasive species, the polyphagous ambrosia beetle, has damaged California's avocado industry and harmed 335 tree species in Southern California.

This study carried out risk assessments on 15 internationally important wood-boring beetle species. For these internationally significant wood-boring beetles, after conducting risk assessments of both their potential invasion consequences and invasion likelihood, all major forest-damaging bark beetle species from the Americas and Europe were categorized as low-risk pests in Taiwan. Two bark beetle species from Southeast Asia, however, were assessed as high-risk pests in Taiwan. This study also completed morphological identification, distribution surveys, and ecological data collection for 30 species of Taiwanese Scolytinae and 20 species of Taiwanese Platypodinae.
