于1990~1995年对栗花麦蛾的生活史、生物学习性进行了研究。结果表明,栗花麦蛾1年1代,以蛹在栗树树干的翘皮内等处越冬,成虫发生期为5月中旬至6月下旬,卵发生期为6月,幼虫为害期为6月至7月上旬,7月中旬幼虫陆续成熟后爬至越冬处结白茧化蛹越冬,蛹期约300d(天)。卵主要产在雄花序和混合花序上,幼虫食害花序,钻蛀幼蓬,导致栗蓬脱落。
From 1990 to 1995, we studied the life history and biological characteristics of the mother flower chestnut moth. The results showed that in the first year of the chestnut flower moth, the pupae overwintered in the bark of the chestnut trunk, the adult period occurred from mid May to the end of June, the egg period was June and the larvae damage stage was 6 From the beginning of July to the beginning of July, the larvae climb to the overwintering at mid-July and the cocoon pupation overwinter. The pupal stage is about 300 days (days). The eggs are mainly produced in the male inflorescences and mixed inflorescences, the larvae eaten inflorescences, drilling borers, resulting in chestnut Peng fall off.
