“…Observations of the present and other studies demonstrate that the leaf area damaged by larvae of C. ochridella may vary significantly among different sites as well as among leaves within the same tree (Kopacka and Zemek 2017). Koskella et al (2017) have also found little explanation for the degree of C. ochridella incidence, when studying barkassociated bacterial communities and horse chestnut bleeding canker disease.…”

“…Two rivers and some streams flow through České Budějovice, as seen from the map. Previous studies [26,35] have demonstrated higher damage to leaves attacked by G. aesculi in the city center than in other areas. At the Nádražní Street site, leaf litter is not removed; therefore, A. hippocastanum leaves are severely infested with C. ohridella every year [35]…”

“…For the purpose of the present study, the city area was divided into eight semi-isolated sites (Table 1). All parameters and the map of the study sites are the same as those in a previous study [35], with the exception that two additional study sites, "Stromovka Park" and "Třebotovice and Kaliště village" were included in the survey. The area of green public open space at both study sites was one ha.…”

The horse chestnut leaf miner Cameraria ohridella (Lepidoptera: Gracillariidae) is an invasive pest of horse chestnut and has spread through Europe since 1985. The horse chestnut leaf blotch Guignardia aesculi (Botryosphaeriales: Botryosphaeriaceae) is a fungal disease that also seriously damages horse chestnut trees in Europe. The interaction between the leaf miner and the fungus has not yet been sufficiently described. Therefore, the aim of the present study was to assess leaf damage inflicted to horse chestnut by both C. ohridella and G. aesculi during the vegetation season and to model their interaction. The damage to leaf area was measured monthly from May to September 2013 in České Budějovice, the Czech Republic. A simple phenomenological model describing the expected dynamics of the two species was developed. The study revealed a significant effect of sampling site and sampling period on the damage caused by both the pest and the fungus. The mathematical model indicates that infestation by C. ohridella is more affected by G. aesculi than vice versa. The possible mechanisms affecting the relationship between G. aesculi and C. ohridella are discussed.

“…Thus, Nardini et al. () observed in north‐east Italy that in early May 2%–3% leaf area was lost at 2 and 6 m above ground; by the end of June, leaf area loss was 30% at 2 m, 18% at 6 m, 10% at 10 m and 8% at 14 m; and by the end of August, it was 85% at 2 m, 75% at 6 m, 65% at 10 m, 55% at 14 m. Spatial analysis in the Czech Republic showed that damage between sites was not related to the infestation of neighbouring areas, indicating that the distribution of C. ohridella is random (Kopačka & Zemek, ). However, Gilbert, Svatoš, Lehmann, and Bacher () found a positive correlation in Bern, Switzerland, between infestation level on a tree and the number of other horse‐chestnut trees within 800 m distance, and in Brussels the proportion of green areas within 100 m and the number of other horse‐chestnut trees within 2,000 m.…”

This account presents information on all aspects of the biology of Aesculus hippocastanum L. (horse‐chestnut) that are relevant to understanding its ecological characteristics and behaviour. The main topics are presented within the standard framework of the Biological Flora of the British Isles: distribution, habitat, communities, responses to biotic factors, responses to environment, structure and physiology, phenology, floral and seed characters, herbivores and disease, history and conservation. Aesculus hippocastanum is a large deciduous tree native to the Balkan Peninsula. Native populations are small (<10,000 trees total) and apparently in decline, but the tree has been widely planted in gardens and streets across Europe and other temperate areas from the 17th century onwards. It was voted the UK's favourite tree in a 2017 poll. As a British neophyte, it is occasionally naturalised in open wooded habitats. Horse‐chestnut is renowned for the beauty of its large (up to 30 cm long), upright panicles of white flowers, and for the large seeds (up to 42 g each) used in the formerly common children's game of “conkers.” More recently, the triterpene glycosides, extractable from various plant parts but especially the seeds, have been widely used in medicine. In much of Europe, horse‐chestnut is affected by chestnut bleeding canker (caused by Pseudomonas syringae pv. aesculi), the horse‐chestnut leaf miner Cameraria ohridella and the leaf blotch fungus Guignardia aesculi. The canker is likely to lead to death of <10% individuals, but seeds of plants infested with the leaf miner are 40%–50% smaller, which may affect long‐term establishment in non‐planted areas.
