“…The odor of volatile compounds as well as their taste provokes specific and precise behavioral responses of insects, i.e., movement away (avoidance) from the non-host or movement towards the host plant (attraction) [ 40 ]. Besides avoidance behavior induced by odor and taste of secondary plant metabolites, non-host plant compounds may also negatively affect consumption and/or impair the digestion and nutrient absorption, interfere with mitochondrial function, and have toxic, genotoxic, and prooxidant effects [ 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 ]. These collateral effects caused by secondary metabolites and, among them essential oils, on behavior and insect physiology are the basis for their application as botanical insecticides.…”

The gypsy moth (Lymantria dispar L. (Lepidoptera: Erebidae)) is a serious pest of hardwood forests. In the search for an environmentally safe means of its control, we assessed the impact of different concentrations of essential oils (EOs) from the seeds of three Apiaceae plants (anise Pimpinella anisum, dill Anethum graveolens, and fennel Foeniculum vulgare) on behavior, mortality, molting and nutritional physiology of gypsy moth larvae (GML). EOs efficacy was compared with commercial insecticide NeemAzal®-T/S (neem). The main compounds in the Eos were trans-anethole in anise; carvone, limonene, and α-phellandrene in dill; and trans-anethole and fenchone in fennel seed. At 1% EOs concentration, anise and fennel were better antifeedants and all three EOs were more toxic than neem. Neem was superior in delaying 2nd to 3rd larval molting. In the 4th instar, 0.5%, anise and fennel EOs decreased relative consumption rate more than neem, whereas all three EOs were more effective in reducing growth rate, approximate digestibility and efficiency of conversion of food into body mass leading to higher metabolic costs to GML. Decrease in consumption and metabolic parameters compared to control GML confirmed that adverse effects of the EOs stem from both pre- and post-ingestive mechanisms. The results indicate the potential of three EOs to be used for gypsy moth control.

“…As E. alphitoides has been present in Europe for more than 100 years, a lot is known about it (Desprez-Loustau et al, 2011;Marçais and Desprez-Loustau, 2014;Lonsdale, 2015;Kebert et al, 2022;Mieslerová et al, 2022). L. dispar, T. viridana, E. defoliaria, and O. brumata have also been a topic of many studies (Ivashov et al, 2002;Tikkanen and Julkunen-Tiitto, 2003;Glavendekić, 2010;Milanović et al, 2020aMilanović et al, ,b, 2022. C. arcuata is still a new species for Europe so it is currently intensively studied (Bernardinelli, 2006;Franjević et al, 2018;Drekić et al, 2019;Nikolic et al, 2019;Csóka et al, 2020;Kern et al, 2021;Marković et al, 2021a;Bălăcenoiu et al, 2021b;Paulin et al, 2023;Stancă-Moise et al, 2023;Valdés-Correcher et al, 2023).…”

Pedunculate oak (Quercus robur L., 1753) is one of the widely distributed oak species in Europe. A large number of organisms develop on its leaves. To determine the extent to which the oak powdery mildew, oak lace bug, and other foliofagous insects affect the growth of young oak trees, three experimental fields were selected in a 10-year-old pedunculate oak stand. In each of them, 50 trees were randomly selected, and their height was measured at the beginning of the vegetative season. The first experimental field was treated with a systemic insecticide, the second with a systemic fungicide, and the third, a comparison area, with water, during the entire vegetative season. At the end of the vegetative season, 25 plants with one apical branch were selected in each experimental field. Their height was measured, and 20 leaves were taken from each plant to determine the extent of the damage on them at the end of the experiment. After processing the obtained data, it was determined that: 1. Both foliofagous insects and oak leaf inhabiting fungi affect the growth of the oak trees significantly; 2. The oak lace bug did not influence the growth of the young trees significantly, as its abundance was low in all of the experimental areas; 3. The greatest damage on the leaves was caused by defoliator insects, which is why they contributed the most to the decrease in growth caused by insects; 4. The influence of the foliofagous insects on the growth of the trees was not significantly different from the influence of fungi; 5. Suppression of oak powdery mildew and foliofagous insects on young trees is useful as it positively influences the vitality and growth of those trees, and contributes to economic and ecological gain.

“…Turkey oak is the most preferred and suitable among oak species in Balkan Peninsula [23] and thus its forests might be common sites where GM outbreaks begin and spread to other forests [24]. After defoliation of optimal oak hosts during outbreak, GM actively searches for available food and may accept less suitable hosts for feeding and oviposition [25][26][27]. For instance, during the last GM outbreak in Serbia, significant amount of beech forests were completely defoliated [28].…”

Pest resistance of trees should be taken into account in future forest strategy planning and predicting risks of defoliation. The gypsy moth (GM) (Lymantria dispar L.) is a serious forest pest with outbreaking population dynamics. To estimate defoliation risk of the most widely distributed tree species in Balkan Peninsula and Europe (Turkey oak Quercus cerris L., European beech Fagus sylvatica L. and hornbeam Carpinus betulus L.), we carried out laboratory feeding trials and investigated their acceptability and suitability for GM development. We determined morphological and chemical attributes of these hosts as well as larval host preference, growth and nutritional indices. Preference, growth, and efficiency of food conversion into biomass were ranked in the order: Turkey oak ˃ European beech ˃ hornbeam. Hornbeam was the most avoided and showed the lowest conversion efficiency although, comparing to optimal oak host, its leaves were less tough, contained more water and exhibited similar values of nitrogen (index of protein content) and C/N ratio (index of investment into carbon based plant defense). We suggest that hornbeam and beech leaf chemical profiles should be further studied to reveal specific compounds that impose high metabolic cost to GM larvae. Moreover, additional research are needed to understand how intermediate hosts in natural populations affect GM outbreaks.
