摘要
通过果园定点调查和室内饲养，观察了贵州省施秉县发生的葡萄羽蛾的形态特征和生物学特性。该虫一年发生三代，以第二代幼虫危害葡萄果实最重，一至三代幼虫危害盛期分别为６月上旬、６月底至７月初、８月初。８月中旬末以第三代老熟幼虫入残桩、病虫枝。
An investigation on biological properties and morphological characters of plume moth in grape were conducted at fixed site in the orchard and fed in the room.The plume moth occurred three generations a year.The second generation larvea caused the most demage to the fruit.The damage peak for 1～3 generations larvea was respectively in the first ten days of June,the last June to early July,and the early August.The full grown larvea of the third generation would overwinter in the stump,injured branches,and hole of withered twig.
