| 中文摘要: |
| １９９５～１９９７年，通过对韭菜蛾室内外观察研究，发现韭菜蛾在沈阳一年发生４～５代，世代重叠严重。无滞育虫态，以成虫和蛹越冬，翌年４月中旬越冬成虫开始活动，第１代成虫发生在６月中旬。以幼虫在田间危害，幼虫发育最适温度为１９～２３℃，种群消长周年出现两个高峰。防治该虫应以初夏、秋季防治为主，重点防治秋季第４、５代；每代防治关键时期为幼虫孵化盛期，在幼虫未蛀入茎内危害之前，选用菊酯类杀虫剂喷雾防治。 |
| 英文摘要: |
| During 1995-1997, the bionomics of Acrolepia alliella Meyick were studied in Shenyang. Its generations overlapped severely in 4 or 5 generations a year. Its pupa and adults could pass through winter in Shenyang and overwintered adults emerged in the middle of April. Threshold temperature of the development for a whole generation was 731 and thermal constant was 416.42 daydegree. In fields, its larvae caused great damage to Lily family vegetables, and annual curve of the population dynamics appears in double-peak. The investigation of spatial distribution pattem showed that the larvae belonged to uniform distribution in fields. The pests should be controlled in larval incubation period of eath generation in early Summer and in Autumn. |
