Abstract
I. 鐘麻粟螟(Pyrausta nubilalis Hub.)在臺灣之鐘麻栽培區域中，發生情彩相當嚴重，每年都造成災害。目前各地麻農咸以不能保障其收益，多不願再繼續栽植鐘麻。據查民國41年在雲林、嘉義、臺南三縣鐘麻之推廣面積有636公頃；至民國42年鐘麻在該三縣推廣之總面積，尚不及16公頃；民國43-45年，除民間零落之栽培外，已無法推廣種植。
Pyausta nubilalis Hübner (Lep., Pyralididae), commonly known as the European corn borer, is the chief menace to the cultivation of Ambari hemp (Hibiscus cannabinus Linne) in Taiwan. Its outbreak in 1952 at Yunlin, Chiayi and Tainan hsiens had immediately resulted the sudden fall (from 636 ha. to 16 ha.) of acreage in this area next year. This formidable pest has 5 generations each year and requires 30-35 days (generally 43-48 days) to complete immature developments. Insofar as the Ambari hemp is concerned, larvae of the first generation are the most destructive.
