摘要
金纹细蛾是苹果等果树上一种常见的潜叶性害虫 ,东亚特有种。自 2 0世纪 70年代以来 ,金纹细蛾的危害在我国逐渐严重 ,成为果园的主要害虫之一 ,1 993年全国性大暴发。为有效地对该虫进行测报和防治 ,作者对金纹细蛾的暴发原因进行了初步探讨 ,结论如下 :( 1 )我国 80年代以来高感品种富士苹果的种植面积不断扩大 ,并进一步矮化密植 ,为该虫提供了好的营养和适宜的生态位 ;( 2 )大量广谱性化学合成农药的长期使用 ,杀伤了金纹细蛾的大部分天敌 ;( 3)近 2 0年来全球性气温上升 ,有利于金纹细蛾的繁殖。
Golden yellow gracilariid (Lithocolletis ringoniella Matsumura)(Lepidoptera:Gracilariidae),an endemic species of Eastern Asia,is a common pest in apple and several other fruit trees.Its popularity in apple orchards has increased gradually since 1970's.Eventually it became one of the key pests in apple orchards,and caused a nationwide outbreak in China in 1993.In order to facilitate the prediction and management of this pest,a primary study on the main causes of its outbreak had been designed and carried out.The conclusions is as followings: (1)Continuous expanding cultivated area of Fuji,a highly susceptible strain,accompanied by dwarfing culture and dense planting of this apple trees,which favor the insect in nutrition and niche; (2)Applying a great quantity of chemical insecticides,especially the wide spectrum insecticides,which kill most natural enemies of the insect; (3) Temperature continuous raising during the last 20 years,which promoted the reproduction of the insect species.
