“…The insect only hibernates at the stage of the pupa and the pupation takes place after the first frost. Various authors have shown that the number of generations depends on the sources of nutrients and weather conditions (Baraniak et al, 2005). The studies by Stygar et al (2017) found that the main nutrients in the leaves of horse chestnut for the caterpillars are starch and sucrose, which is confirmed by high amylase activity, as well as activity of maltase and sucrose.…”

In the last two decades, the horse chestnut (Aesculus hippocastanum L.), introduced into the steppe zone of Ukraine, has been severely affected by the horse chestnut leaf miner Camereraria ohridella Deschka & Dimič, 1986, which results in damage to the assimilating organs, premature leaf defoliation and, as a consequence, a significant reduction in the reserve substances required for normal life of the plant. In recent studies, the main focus has been placed on the study of the pest’s effects on the non-enzymatic antioxidant protection system of the representatives of the genus Aesculus, while the enzymatic system of horse chestnut protection from the active forms of oxygen under stress is still poorly understood. The purpose of this study was to evaluate the reaction of catalase and two peroxidases of A. hippocastanum leaves, which differ in the level of damage by C. ohridella. The intensity of damage to A. hippocastanum leaves by the horse chestnut leaf miner in the park zones and botanical gardens of Dnipro city was determined, the activity and isoenzyme composition of benzidine-peroxidase, activity of guaiacol-peroxidase and catalase were measured. The lowest average benzidine-peroxidase activity was found in the group of trees with low level of leaf blight and the highest activity – in the group with high level. The opposite dependence was shown by catalase, the activity of which significantly decreases with increasing level of damage inflicted by the phytophage on the chestnut’s assimilating organs. Based on the determination of the variation coefficients, it has been shown that benzidine-peroxidase activity has a higher level of variability than that of catalase and guaiacol-peroxidase. It is established that under the influence of the leaf miner, activity of guaiacol-peroxidase was significantly higher by 87.1% and 75.6%, respectively, for medium and high levels of damage caused to the leaf by this phytophage as compared to that for low levels of damage. The increased level of leaf damage caused by the phytophage is reflected in the change in the isozyme profile of benzidine-peroxidase. The high activity of benzidine-peroxidase in the leaves of A. hippocastanum is due to the presence of several molecular forms that exhibit maximum activity in the narrow pH range (4.15–4.69). Quantitative redistribution of activity between the different molecular forms of benzidine peroxidase can be considered as the main regularity of changes in the expression of benzidine-peroxidase caused by different levels of leaf damage. The results showed that only one benzidine-peroxidase isoform with an isoelectric point of 4.15 shows a significant increase in activity (on average by 2.1 times) in A. hippocastanum leaves with medium and high levels of damage by C. ohridella. Significant reduction in activity is reported for dominant isoperoxidase with an isoelectric point of 4.25 revealing medium pest damage, and for high damage only a decreasing tendency is shown. The data obtained show that horse chestnut trees can specifically respond to mechanical damage by C. ohridella to leaves due to the changes in the activity of individual molecular forms of peroxidase. Further studies of oxidative metabolism are needed to understand the formation of resistance of representatives of the Aesculus genus to damage caused by this moth species based on a wider range of redox enzymes.

“…Studying the biology and ecology of C. ohridella, especially its ecological niche, may lead to the development of appropriate biological or more complex methods for limiting its negative effect on A. hippocastanum and the closely related (and highly susceptible) Aesculus turbinata Blume. Moreover, there are many other potential host plants at risk of being attacked by this pest (Péré et al, 2010;D'Costa et al, 2013D'Costa et al, , 2014Walczak et al, 2017).…”

The range of C. ohridella continues to expand; in 2003, it reached southern Sweden (Rämert et al., 2011), and a recent report indicates that this insect is in Kazakhstan (Gninenko et al., 2017). Its main host, horse chestnut Aesculus hippocastanum L., was introduced into central Europe in XVI c. (Ravazzi & Caudullo, 2016). Currently, trees of this species are common throughout the continent. They occur in both urban and rural environments and are commonly planted in lines or alleys. This species has high decorative value, especially during the fl owering period, and its chestnuts that fall to the ground attract the attention of children and, as described by Gwiazdowicz & Wiśniewski (2011) are also of interest to senior citizens. Escin, the mixture of triterpenoid saponins found in the tissues of A. hippocastanum, is used to treat chronic venous insuffi ciency, haemorrhoids and post-operative oedema (Sirtori, 2001). Escin also exhibits anti-cancer effects (Cheong et al., 2018). Fujimura et al.

“…In holometabolous insects, allocation and variation in the nutritional quality of larval food resources result in changes in life history and/or morphological traits and consequently have effects on the fitness of adult individuals (Boggs 1981;Armbruster and Hutchinson 2002;Awmack and Leather 2002). As shown by (Walczak et al 2017), a mine density, survival, pupal mass, and potential fecundity of C. ohridella were significantly lower on Ae. glabra than on Ae.…”

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.
