摘要：研究了珍珠花(Lyonia ovalifolia Drude)上一种潜叶细蛾—— 南烛尖细蛾（Acrocercops transecta Meyrick) (鳞翅目：细蛾科) 的生物学特性，结果表明：南烛尖细蛾于江西南部一年发生3代，且有世代重叠现象，每年的发生时间因纬度而异；此外，还描述了南烛尖细蛾的潜道特征、形态结构及其生活史。该虫潜食珍珠花的叶片，叶片被取食部分仅留下很薄的灰白色透明的表皮，严重削弱了叶片光合作用。

Abstract：The biological characteristics of leaf miner Acrocercops transecta (Lepidoptera：Gracillariidae)in Lyonia ovalifolia were systematically studied．Acrocercops transecta had three generations every year in south Jiangxi．Its generations ovedapped and occurrence period varied with different latitudes．In addition，the mining tunnel characteristics，morphology and life history of Acrocercops transecta were described，and the photos of larvae，pupa，adult，leaf mines and male／female genital organs were given．This insect mined the leaves of Lyonia ovalifolia．Only hoar transparent leaf epidermis was left in the mined parts，thus leaf photosynthesis
decreased significantly．

Key words：Lyonia ovalifolia；Acrocercops transecta；Leaf miner；Biological characteristic
