Apparent competition, through the action of shared natural enemies, is frequently suggested as a possible mechanism underlying the impact of invasive alien species on native species, but examples are rare, particularly in insects. A previous study showed that the beech leaf mining weevil, Orchestes fagi, was significantly less abundant close to horse-chestnut trees infested by the invasive...

1. The horse-chestnut leaf miner Cameraria ohridella is an invasive moth in Europe and a serious pest of horse-chestnut Aesculus hippocastanum. The moth also occasionally attacks sycamore maple Acer pseudoplatanus, when situated beside infested horse-chestnuts. 2. The main objective of the present study was to provide an overview of the relationship between C....

Species richness and abundance of native leaf miners are affected by the presence of the invasive horse-chestnut leaf miner

In: Biological Invasions, 2010, vol. 12, no. 5, p. 1011-1021

The effect of the alien horse-chestnut leaf miner, Cameraria ohridella, on native fauna was studied by comparing the species richness of native leaf miner communities and the abundance of selected native leaf miner species in the presence and absence of horse-chestnut trees infested by C. ohridella, in various environments in Europe. The species richness of native leaf miner...

Ecological impact of the invasive horse-chestnut leaf miner, "Cameraria ohridella" Deschka & Dimic (Lepidoptera: Gracillariidae) on native species

Thèse de doctorat : Université de Neuchâtel, 2009 ; Th. 2093.

The horse-chestnut leaf miner, Cameraria ohridella, is the first leaf miner and first major pest known to attack the white flowering horse-chestnut tree, Aesculus hippocastanum, native to the Balkans and introduced in Central Europe as an ornamental urban tree. This moth, which probably originates from the Balkans, was first discovered in Macedonia in 1984 and has since invaded most...
