“…This study aimed at investigative O 3 effects on the beetle as a sum of direct and indirect effects; insects would experience both direct and indirect effects in an O 3 -polluted environment. Hence, this study does not provide the opportunity to separate the direct and indirect effects of O 3 (Telesnicki 2015(Telesnicki , 2018. However, previous bioassays, where this beetle was not directly exposed to O 3 , suggest that EOZ leaves not only were not harmful but were often preferred over AOZ leaves by the beetles.…”

Tropospheric ozone (O 3) is a naturally occurring gas in the atmosphere. However, the concentration of O 3 increased in the 20 th century. Although the effects of O 3 on vegetation have been extensively studied since the 1950s, limited information exists regarding the effects of O 3 on insect herbivores. In particular, evidence is lacking regarding the effects of O 3 on the biology of insect herbivores. Agelastica coerulea (Baly, 1874) is a coleopteran species that grazes on Betulaceae plants. In this study, to investigate the effects of O 3 on A. coerulea biology for the first time, female adult insects were collected from Japanese white birch trees grown in a Free Air Controlled Exposure System (FACE) in Sapporo, Japan. These beetles inhabited trees exposed either to ambient or to elevated O 3 for 23 days. After 2 collection, the enzyme activities in the beetles were measured. Elevated O 3 led to a greater total antioxidant activity and lower α-and β-esterase activities, a phenomenon that may suggest an increased resistance of the beetles to stress. Our results are further discussed with regard to biological and toxicological aspects. Collectively, our findings indicate that total antioxidants and α-and β-esterase activities can serve as effective O 3 biomarker systems in this beetle species. This adaptive response of the beetle, which was induced by moderate O 3 exposure, should be further tested across generations and for its protection against greater exposure.

“…Holopainen and Kössi 71 observed that ozone can stimulate aphid population growth of aphids feeding on spruce seedlings exposed to 80 ppb of ozone, but aphids are not affected when the host plants are exposed to other levels of ozone or when the exposure continues until shoot maturity. Other studies showed that aphids tolerate well the plant-mediated effects of ozone and are not affected by the exposure 72 – 74 . We also observed that the number of Lygus pratensis bugs was higher on plants exposed to ozone when they were 3 weeks old.…”

“…This contrasts with the results obtained by Manninen et al 72 for another Lygus species ( Lygus rugulipennis ), whose performance was reduced in ozone-exposed Scots pine seedlings. Except for the study of Telesnicki et al 74 that used Triticum aestivum as the plant species, all other studies mentioned above on sucking herbivores were performed with perennial plant species, meaning that the longevity of the plant may influence its ozone plant-mediated effects on the performance of the herbivores.…”

Exposure of plants to environmental stressors can modify their metabolism, interactions with other organisms and reproductive success. Tropospheric ozone is a source of plant stress. We investigated how an acute exposure to ozone at different times of plant development affects reproductive performance, as well as the flowering patterns and the interactions with pollinators and herbivores, of wild mustard plants. The number of open flowers was higher on plants exposed to ozone at earlier ages than on the respective controls, while plants exposed at later ages showed a tendency for decreased number of open flowers. The changes in the number of flowers provided a good explanation for the ozone-induced effects on reproductive performance and on pollinator visitation. Ozone exposure at earlier ages also led to either earlier or extended flowering periods. Moreover, ozone tended to increase herbivore abundance, with responses depending on herbivore taxa and the plant age at the time of ozone exposure. These results suggest that the effects of ozone exposure depend on the developmental stage of the plant, affecting the flowering patterns in different directions, with consequences for pollination and reproduction of annual crops and wild species.

“…Choi et al [71] found that even at low SO 2 concentrations, extensive crop tissue damage also occurred due to the formation of sulphate. This negative effect of O 3 arises from the disturbance of the equilibrium between production and the scavenging of reactive oxygen species (ROS) within crop tissues, and Telesnicki et al [72] found that O 3 reduced the antioxidant potential in crops and had no effect on lipid peroxidation in plants. Second, the toxic effects of air pollutants would have complex interactions with other environmental stresses, such as the stresses of water, nutrients, salinity, and heavy metals.…”

To determine the effects of air pollution on crop yields, weather, air pollution, and maize and winter wheat yield data from 331 cities in China from 2014 to 2016 were collected and analysed. Furthermore, support vector regression and the crop growth model were applied to extrapolate the air pollution data of Beijing and Hetian and verify the relationship between air pollution and yield. Precisely, heavy air pollution usually occurred in North China, but less than moderate air pollution levels affected crop yields statistically insignificantly. Moreover, both the winter wheat and maize yields increased in moderate air pollution periods but decreased in heavy air pollution periods in 2014, 2015 and 2016. Importantly, a threshold value was necessary for the heavy air pollution periods to trigger a yield decrease. The threshold values of maize in 2015 and 2016 were 7 days and 5 days, respectively, while that of winter wheat was 10 days in both 2015 and 2016. Once the heavy air pollution periods exceeded the threshold value, both the winter wheat and maize yields decreased linearly with the periods. PM2.5 was the main air pollutant in Beijing in 2014, while PM2.5 and PM10 were the main air pollutants in Hetian in both 2015 and 2016. Regardless of whether the main air pollutant was PM2.5 or PM10, the simulated potential winter wheat yields by the crop growth model with moderate air pollution for the whole growth period were all higher than the yields under observed and heavy air pollution conditions.
