The horse-chestnut leaf miner was first observed in Macedonia in 1984, and was described as a new species in 1986.〔〔(Horse chestnut leaf miner, Cameraria ohridella Desch. & Dem. (Lepidoptera: Gracillariidae) ) Exotic pest alert - Uk Forestry Commission〕 Its larvae are leaf miners on the Common Horse-chestnut (''Aesculus hippocastanum''). The horse-chestnut leafminer was first collected and inadvertently pressed in herbarium sheets by the botanist Theodor von Heldreich in central Greece in 1879. ==Damage== ''Cameraria ohridella'' causes significant damage, mainly late summer browning, to the appearance of horse-chestnut trees. Despite the poor appearance of these infested trees, there is no evidence that damage by the moth leads to tree death. Seed weight, photosynthetic storage and reproductive capacity may however be reduced.〔Percival, G. C., Barrow I., Novissa K., Keary I., & Pennington P. 2011. The impact of horse chestnut leaf miner (''Cameraria ohridella'' Deschka and Dimić; HCLM) on vitality, growth and reproduction of ''Aesculus hippocastanum'' L. ''Urban Forestry & Urban Greening''. 10: 11-17〕 Trees survive repeated infestations and re-flush normally in the following year. It appears that most of the damage caused by the moth occurs too late in the growing season to greatly affect tree performance.〔 Consequently, there is no reason to fell and remove trees just because they are attacked by ''C. ohridella''.〔 The larva feeds in a mine in the leaves of the tree, damaging the leaves and stunting growth. Infected leaves are covered in small brown patches which spread rapidly across the entire tree, giving an autumnal appearance. Eventually the leaves die and drop off; when new ones grow they are again infected. This cycle can repeat itself several times in one season. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Horse-chestnut leaf miner」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
