We experimentally examined the effects of elevated O3 and whitefly herbivory on tomato volatiles, feeding and oviposition preferences of whiteflies and behavioural responses of Encarsia formosa to these emissions on two tomato genotypes, a wild-type (Wt) and a jasmonic acid (JA) defence-enhanced genotype (JA-OE, 35S). The O3 level and whitefly herbivory significantly increased the total amount of volatile organic compounds (VOCs), monoterpenes, green leaf volatiles (GLVs), and aldehyde volatiles produced by tomato plants. The 35S plants released higher amount of total VOCs and monoterpene volatiles than Wt plants under O3+herbivory treatments. The feeding and oviposition bioassays showed that control plants were preferred by adult whiteflies whereas the 35S plants were not preferred by whiteflies. In the Y-tube tests, O3+herbivory treatment genotypes were preferred by adult E. Formosa. The 35S plants were preferred by adult E. formosa under O3, herbivory and O3+herbivory treatments. Our results demonstrated that elevated O3 and whitefly herbivory significantly increased tomato volatiles, which attracted E. formosa and reduced whitefly feeding. The 35S plants had a higher resistance to B. tabaci than Wt plant. Such changes suggest that the direct and indirect defences of resistant genotypes, such as 35S, could strengthen as the atmospheric O3 concentration increases.

“…It is similar to the result of Populus deltoids that fumigated with ozone. The plant showed a decrease in both chlorophyll and carotenoid [48,49]. This is because carotenoid is one of the antioxidants that has been used in plant tissue to scavenge the reactive oxygen species [50].…”

Abstract-The tropospheric ozone has been projected to increase, and it could harm humans, animals, and vegetation. This study investigates morphological changes in coleus leaves, to assess the change of pigment composition (chlorophyll, carotenoid, and anthocyanin), and to understand color dynamics due to ozone fumigation. Coleus Kong Green (fully green/FG), Coleus Kong Scarlet (green and purple/GP), Coleus Wizard Pastel (yellow and purple/YP), and Coleus Wizard Scarlet (reddish/RD) selected. The materials in this study tested for three different ozone concentrations which were CF (≤ 10 ppb ozone), CF+40 ppb ozone, and CF+150 ppb ozone for 8 hours/day for 30 days. Chlorosis in FG and curling leaf in RD were observed as the symptoms while other cultivars showed different appearances such as expanded purple area (GP and YP) and curled margin (RD). Chlorophyll and carotenoid content significantly decreased in all cultivars while anthocyanin was found increasing except in RD. The color change tended to redder and brighter in all cultivars except RD which was a stable and purple area in GP which was darker. Therefore, different coleus cultivars show different responses and it can be used as an ozone-plant model to investigate pigment composition under ozone exposure.

“…Air pollution can cause damage to vegetation, and combination of several pollutants can aggravate such ef-fects (Oguntimehin et al, 2010b). For example, low concentrations (10 mM) of Flt created adverse effects on red pine seedlings such as decreased needle gas exchange, chlorophyll content, photosynthesis, and foliar damage (Oguntimehin et al, 2008).…”

“…Even if the concentration of individual PAH in the atmosphere is low, they have the potential to cause increased phytotoxicity when present in combination with total PAHs and/or other chemicals (Oguntimehin et al, 2010a, b). For example, ozone was found to have an adverse effect on Japanese pine (Oguntimehin and Sakugawa, 2009) and cherry tomato (Oguntimehin et al, 2010b) in a chamber experiment in which it was administered at 120 ppb in combination with 10 mM fluoranthene (Flt) for 34 days, suggesting that Flt exacerbates the negative effects of ozone. Similarly, increased phytotoxicity was reported in response to the application of Flt in conjugation with acid mist (Oguntimehin et al, 2013).…”

This survey was conducted to analyze particle-associated atmospheric polycyclic aromatic hydrocarbons (PAHs) at a rural site (Kamihaya) in Tanabe, Wakayama Prefecture, central Japan from 2012-2013. Analysis of particulate matter revealed that total PAHs ranged from 0.036 to 10.16 ng m-3 with an average concentration of 3.20 ng m-3. The highest PAHs concentration of 10.16 ng m-3 was observed on September 19, 2012. Significant seasonal variations in PAHs concentrations were observed at the site, with higher values during winter/spring and lower values during summer/autumn. Trajectory analyses suggest that PAHs produced domestically have a greater impact on Kamihaya than those transported from other countries. Molecular diagnostic ratios and principal component analysis showed that atmospheric PAHs primarily arose from industrial and traffic emissions, while wood combustion appeared to be a minor source. Overall, the results of this study suggest that atmospheric PAHs in Kamihaya present a potential threat to the underlying vegetation and may cause damage to plants if combined with other air pollutants.
