| 摘 要： | 甘蔗二点螟（ＣｈｉｌｏｉｎｆｕｓｃａｆｅｌｕｓＳｎｅｌｅｎ）以幼虫越冬。低龄幼虫在种蔗和盖膜宿根蔗内，８℃以上温度即可取食为害，可成为有效虫源。进入滞育的龄期为５龄，一旦滞育，幼虫则不能老熟，但仍可取食和脱皮。老熟幼虫可以休眠方式越冬。预蛹期前有３－５ｄ的后补营养期，蛹历期６－１８ｄ。年发生代数１－４代。

larva. Younger larva in seed sugarcane and in sugarcane field covered with preennial is
harmful over 8. It is an effective source of the insect. Being stagnancy at 5th instar, larva cant
become mature except eating and exuviating. Older larva may aslo hibernate in dormancy.
Chilo infuscatellus has 3-5 days post nutrition period before prepupa stadium and 6-16 days
pupa stadium, It occurs 1-4 generations each year. |

| Keywords: | stagnancy exuviation post nutrition occurring generations |
