摘要

本研究使用雄蟲生殖器與野生雌蟲所產幼蟲之形態特徵鑑定隱斑瓢蟲 (Harmonia yedoensis)，並重新確認此物種棲息於臺灣阿里山中海拔地區的二葉松 (Pinus taiwanensis)。文中詳述此瓢蟲族群的生活史、性別體型雙態性和獵物種類。我們在相同的二葉松植株上發現臺灣地區之新記錄種－四斑瓢蟲 (H. quadripunctata)。

The existence and identity of the ladybird beetle Harmonia yedoensis on the Taiwan red pine Pinus taiwanensis at the middle elevation of Alishan in Central Taiwan were confirmed, based on the male genitalia and larvae as well as the morphology of the larvae reared from gravid females newly collected in the field. Life history characteristics, sexual size dimorphism, and prey species of the Alishan H. yedoensis population were evaluated. On the same host plant, we observed adults of coexisting H. quadripunctata, which is a new record in Taiwan.
