“…Therefore, since foliage density was rather similar in both management systems (see Table 3), the tits' densities did not differ (see Table 4). Considering the synchronization between tree foliage phenology, the development of arboreal caterpillars and the breeding season of tits (Kalapanida and Petrakis 2012;Sanz 2001;Southwood et al 2004), we admit that tits can be attracted to trees with reduced foliage density looking for prey larvae in buds or twigs instead in leaves. However, most of the bird guilds affected by vegetation traits presented none or reduced dependence on oak trees for foraging and nesting: ground birds, shrub birds and leaf warblers.…”

& Context The Iberian cork oak Quercus suber montados are dynamic agro-silvo-pastoral systems, contrasting with the abandonment trend of other Mediterranean forested areas. & Aims We aimed to identify the effect of management type and vegetation features on breeding insectivorous birds and leaf-chewing defoliator insects. & Methods In central Portugal, we selected two groups of 20 sites: dense montados (DM, high cover of cork oaks and low cattle impact) and sparse montados (SM, low cover of oaks and high cattle impact). We collected variables associated with vegetation features, bird community and chewing defoliators. & Results The two systems differed significantly in oak trunk diameter, oak and shrub cover, tree and shrub diversity. Ground bird densities were higher in SM with fragmented shrub cover. In DM, higher woody vegetation cover and diversity can promote shrub birds and leaf warblers.Oak defoliation was mainly attributed to the sawfly Periclista andrei. Sawfly defoliation was significantly higher in SM and negatively correlated with shrub cover. & Conclusions Our results highlight (1) the relevance of management activities conducted at the shrubby layer, (2) the need of an increase in tree diversity and density and (3) the maintenance of a mosaic landscape in order to improve the bird community richness and reduce the defoliation impact in montado system.

“…To obtain wider knowledge about proportion between numerous caterpillars of 'autumn' and 'spring' geometrids, we also collected winter moth larvae from several oak species in various areas, as well as over years in Slovakia and Bulgaria (for more details, see Samples S08-S12 and S15, Table 1). We further analysed relevant data from the literature [25,[30][31][32]. The available data refer to caterpillars on Q. cerris, Q. pubescens, Quercus frainetto Ten., Quercus dalechampii Ten., Quercus polycarpa Schur and a few other oak species in Slovakia, Bulgaria and Greece.…”

Species within the group of winter moths (Geometridae) are important oak defoliators in European forests. Adults of these species emerge either in late autumn (‘autumn species’) or in early spring (‘spring species’), and caterpillars of both ‘autumn’ and ‘spring’ species appear in spring. The abundance of adults assessed by regular monitoring allows the prediction of the defoliation intensity in trees by caterpillars in the following spring. ‘Autumn species’ (mostly a single one, Operophtera brumata) are monitored by forestry practices as pests, whereas ‘spring species’ are often not paid any attention. We hypothesised that ‘spring species’ could also have an important share in caterpillar assemblages in oak forests. We aimed to study the proportions between ‘autumn’ and ‘spring’ species in adult and larval stages. In a xeric thermophilous oak forest in southern Slovakia, Central Europe, we collected adult moths using sticky bands set up on trunks of Quercus pubescens during the winter of 2014–2015 and caterpillars from other trees belonging to the same oak species over the following spring. We also captured caterpillars from several oak species in various areas and over different years in Slovakia and Bulgaria, and we compiled relevant literature data. ‘Spring species’ recorded from a unique forest as adults during winter and as caterpillars in the following spring were significantly more abundant than ‘autumn species.’ Moreover, ‘spring species’ from Slovakian forests, regardless of the locality, the oak species and the year of sampling, reached high proportions, mostly over 50% of individuals in caterpillar assemblages. The ‘spring species’ Agriopis leucophaearia was the most abundant, followed by the ‘autumn species’ Operophtera brumata. ‘Spring species’ accounted for more than 50% of individuals in caterpillar assemblages in the Balkan Peninsula (Bulgaria) concerning one case, and they were of little importance in northern Greece. We recommend monitoring all winter moth adults (‘autumn’ and ‘spring’ species together) continuously in forestry practices, using sticky bands on oak trees from late autumn to early spring.

“…The southern boundary of the natural range cuts the northern mountainous part of Israel (Legalov and Friedman, 2007). It is mentioned to occur in Syria (Weil et al, 2011), southern Turkey (Avgın and Colonnelli, 2011), Greece (Bohr, Winkelmann and Bayer, 2011;Kalapanida and Petrakis, 2012), almost in entire Italy incl.

“…Overpopulated, they can damage more than 50 % of leaves (Francke-Grosmann, 1974) or nearly all of them (Escherich, 1923). For example Lampert (1909), Schaufuss (1916Schaufuss ( ), Živojinovič (1948, Gusev and Rimskij-Korsakov (1953), Vasiljev et al (1975), Goloverda and Mozoľ (1977), Gogola et al (1998), Wilkie (2010), Kalapanida and Petrakis (2012) and other authors take the species for a pest on young oak trees. On C. sativa, the beetles may damage flower buds by their maturation feeding (Juhásová et al, 2010).…”

The study deals with the biology of Attelabus nitens (Scop.) in the Brno region. In the growing season of 2014, 35 field inspections were made at 10 sites in the intervals of three-to-seven days. Leaf rolls were found on Quercus petraea, Q. dalechampii, Q. robur, Q. pubescens and Q. cerris, rarely on Castanea sativa. Hibernating in the shed leaf rolls are larvae of the second instar. These pupate in the rolls during the second half of April and beginning of May. At the turn of April and May, beetles fly onto host woody plants of the 1 st age class. They damage about 30 cm 2 of leaves in two months. Females create about 30 leaf rolls into which they lay 1 to 5 (on average 1.1) eggs. The species develops through two larval instars, which damage 1.7 to 2.3 cm 2 of leaves and come of age towards the end of the growing season. On the primary shoots of oaks (with relatively large leaves), the females rolled below-average sized leaves. On the secondary shoots (with relatively small leaves), they rolled leaves of average to above-average size. The female gnaws a deep mine into the main vein (in a third of its length) from the adaxial side first. Then she makes a cross cut into the blade from both sides up to the main vein, which is damaged only on the surface. Into thicker sections of veins she bites out (mainly from the abaxial side) on average 350 cross cuts. Only then, the female folds the wilted leaf part adaxially along the main vein and after having laid an egg (eggs), she rolls the blade from the end into a transversal cylindrical roll. On the leaves of Quercus spp. with an average area of 14.3 cm 2 , the females roll on average 11.9 cm 2 (83.2 %). During the growing period, 36 % of individuals died in the leaf rolls on primary shoots and 28 % of individuals died in the leaf rolls on secondary shoots.
