“…Such variation in host suitability could presumably occur even among introduced populations. Differences in susceptibility to the leaf miner at the level of individual trees and between cultivars are documented for A. hippocastanum (Straw & Tilbury, 2006;Bačovský et al, 2017).…”

“…On the contrary, very high mortality due to other causes observed on A. glabra was mostly a result of host plant chemistry and not intra-specifi c competition, because mine density was low. Secondary metabolites play an important role in plant defense against herbivores (Wink, 1988;Bennett & Wallsgrove, 1994) and are probably also responsible for the resistance of some Aesculus species to C. ohridella (Bačovský et al, 2017). For example, increased level of polyphenolic compounds, especially polymeric procyanidins, found in A. glabra, A. parvifl ora Walt.…”

Abstract. Performance of the invasive horse-chestnut leaf miner, Cameraria ohridella Deschka & Dimic, 1986 (Lepidoptera: Gracillariidae), was studied on two host plants: the white-fl owering horse-chestnut Aesculus hippocastanum L. and the Ohio buckeye Aesculus glabra Willd. C. ohridella developed successfully on both host plants; however, mine density and survival were much higher on A. hippocastanum than on A. glabra. The pupal mass and potential fecundity were strongly affected by the host plant on which the larvae fed. On A. hippocastanum pupae were signifi cantly heavier and females more fecund than those on A. glabra. Furthermore, on both host plants there was a signifi cant positive correlation between the number of oocytes in ovaries and pupal body mass, and as a consequence, heavier females produced more eggs. Our study demonstrates that the mine density, survival, pupal mass and potential fecundity were signifi cantly lower on A. glabra than on A. hippocastanum. The observed lower performance of C. ohridella on the exotic host plant was assumed to be due to its poor food quality (nutritional and chemical composition).

“…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. In addition, other studies have demonstrated that phenolic compounds in leaves (Oszmianski et al 2014;Paterska et al 2017) and/or genetic background of Aesculus trees (Bacovsky et al 2017) may partially explain their susceptibility to the pest. However, despite the present study included a number of trees with possibly different genetic backgrounds, within each site the overall degree of damage from C. ohridella was similar, indicating the need for more detailed studies.…”

The leaf-miner moth Cameraria ohridella, a pest in Central Europe, causes severe damage to trees. Host-associated differentiation (HAD) for this species has been suggested previously based on the occurrence of a specific mitochondrial haplotype. We assessed genetic diversity and population structure for sympatrically occurring individuals collected in association with two host species, Ohio buckeye (Aesculus glabra) and horse chestnut (Ae. hippocastanum), using six microsatellite loci (SSR) and mtDNA sequences that encode parts of cytochrome oxidase I and II. To infer population structure and assign individuals to clusters, we employed Bayesian clustering. We further characterized the relationships between genetic distance and geographical distance (IBD) in analyzed samples. Although our results derived from the SSR loci analyses demonstrating that there was no population substructuring caused by the hosts, we found evidence of differences in wing size, which might be attributed to the quality of food resources available to larvae. The population structure with K = 2 cannot be interpreted as the result of IBD; rather, it reflects a population differentiation due to demographic or genetic processes (e.g., an origin of invaders). Although genetic diversity was relatively high (H e > 0.5), the population had a deficiency of heterozygotes (F IS > 0), which was most likely due to nonrandom mating and, possibly, a Wahlund effect. A star-like haplotype network and negative Tajima's D support the genetic effect of bottleneck followed by population expansion. Based on presumably neutral markers, we conclude that C. ohridella appeared to be a good model for studying evolution toward a generalist invasive species, rather than HAD.
