“…Higher fecundity of BPH in the present study ultimately resulted in proliferated BPH population under elevated condition than ambient condition. This has been reported earlier in case of cotton aphid, Aphis gossypii [ 33 ]; grain aphid, S. avenae [ 27 ] and peach aphid, Myzus persicae [ 34 ]; brown planthopper N. lugens [ 21 ] and corn leaf aphid R. maidis [ 30 ] while, decrease in fecundity was observed in case of woolly beech aphid, Phyllaphis fagi [ 35 ] red spider mite, Tetranychus urticae [ 36 ] and pea aphid, Acyrthosiphon pisum [ 37 ].…”

Influence of elevated CO2 (570 ± 25 ppm) and elevated temperature (≃3 °C higher than ambient) on rice (Oryza sativa L.) and brown planthopper (BPH), Nilaparvata lugens (Stal.) was studied in open top chambers during rainy season of 2013. Elevated CO2 and temperature exhibited positive effect on BPH multiplication thus enhancing its population (55.2 ± 5.7 hoppers/hill) in comparison to ambient CO2 and temperature (25.5 ± 2.1 hoppers/hill). Elevated CO2 + temperature significantly reduced the adult longevity and nymphal duration by 17.4 and 18.5 % respectively, however elevated conditions increased BPH fecundity by 29.5 %. In rice crop, interactive effect of elevated CO2 and temperature led to an increase in the number of tillers (20.1 %) and canopy circumference (30.4 %), but resulted in a decrease of reproductive tillers (10.8 %), seeds/panicle (10.9 %) and 1000-seed weight (8.6 %) thereby reducing grain yield (9.8 %). Moreover, positive effect of increased CO2 concentration and temperature on BPH population exacerbates the damage (30.6) which in turn coupled with the plant traits to hampering production.

“…Most studies that have investigated the effect of elevated CO 2 on leaf thickness have found that it increases (Pritchard et al . 1999), and this may be associated with increased total mesophyll cross‐sectional area (Radaglou & Jarvis 1992), an extra layer of palisade mesophyll (Thomas & Harvey 1983), or an increase in the thickness of the epidermis (Bouteleb Joutei et al . 2000).…”

Interactive effects of elevated CO₂ and temperature on the leaf‐miner Dialectica scalariella Zeller (Lepidoptera: Gracillariidae) in Paterson's Curse, Echium plantagineum (Boraginaceae)

Doubling of the current atmospheric CO2 concentration, and an increase in global mean annual temperatures of 1.5–6 °C, have been predicted to occur by the end of this century. Whilst the separate effects of CO2 and temperature on plant–insect interactions have been examined in a number of studies, few have investigated their combined impact. We carried out a factorial experiment to explore the effect of a doubling of CO2 concentration and a 3 °C temperature increase on the development of a complete generation of the leaf‐miner, Dialectica scalariella, in the host plant Paterson's Curse, Echium plantagineum. Elevated CO2 increased biomass, reduced leaf N and increased C:N ratios in the host plants. Leaf thickness also increased under elevated CO2, but only in the high‐temperature treatment. Female D. scalariella did not discriminate between plants grown at the different CO2 levels when ovipositing, despite the reduction in foliage quality under elevated CO2. Overall, the negative response of D. scalariella to elevated CO2 was greater than for many species of free‐living insects, presumably because of the limited mobility imposed by the leaf‐mining habit. Development was accelerated at the high temperature and slowed under elevated CO2. The net result was a reduction in development time of ∼14 days in the elevated CO2/high temperature treatment, compared to the ambient CO2/low temperature treatment. Larval survivorship and adult moth weight were both affected by a significant interaction between CO2 and temperature. At the low temperature, CO2 had little effect on survivorship, but at the high temperature, survivorship was significantly reduced under elevated CO2. Similarly, elevated CO2 had a stronger negative effect on adult moth weight when combined with the high‐temperature treatment. A possible explanation for these results is that the high temperature accelerated insect development to such an extent that the larvae did not have sufficient feeding time to compensate for the poorer quality of the foliage. The frequency with which interactions between CO2 and temperature affected both plant and insect performance in this study highlights the need for caution when predicting the effects of future climate change on plant–insect interactions from single‐factor experiments.

“…Any reduction in host plant quality is likely to reduce herbivore fitness, through changes in fecundity, survivorship or development rates (e.g. Fajer et al ., 1989; Coviella & Trumble, 1999; Stiling et al ., 1999; Agrell et al ., 2000; Boutaleb‐Joutei et al ., 2000). There are also examples where elevated CO 2 increases plant quality for herbivory (Awmack & Harrington, 2000; Goverde et al ., 1999).…”

We report the results of a study investigating the influence of elevated CO2 on species interactions across three trophic levels: a plant (Brassica oleracea), two aphid herbivores (the generalist Myzus persicae and the specialist Brevicoryne brassicae), and two natural enemies (the coccinellid Hippodamia convergens (ladybird) and the parasitoid wasp Diaeretiella rapae). Brassica oleracea plants reared under elevated CO2 conditions (650 ppmv vs. 350 ppmv) were larger and had decreased water and nitrogen content. Brevicoryne brassicae reared on plants grown in elevated CO2 were larger and accumulated more fat, while there was no change in M. persicae traits. Fecundity of individual aphids appeared to be increased when reared on plants grown in elevated CO2. However, these differences were generally lost when aphids were reared in colonies, suggesting that such changes in plant quality will have subtle effects on aphid intraspecific interactions. Nevertheless, CO2 treatment did influence aphid distribution on plants, with significantly fewer M. persicae found on the shoots, and B. brassicae was only found on senescing leaves, when colonies were reared on plants grown in elevated CO2. We reared B. brassicae and M. persicae in competition on plants grown at both the CO2 concentration treatments. We found a significantly lower ratio of M. persicae: B. brassicae on plants grown under elevated CO2 conditions, strongly suggesting that increasing CO2 concentrations can alter the outcome of competition among insect herbivores. This was also reflected in the distribution of the aphids on the plants. While the CO2 treatment did not influence where B. brassicae were found, fewer M. persicae were present on senescing leaves under elevated CO2 conditions. Changes in plant quality resulting from the CO2 treatments did not appear to alter aphid quality as prey species, as the number consumed by the ladybird H. convergens, and the number parasitised by the parasitoid wasp D. rapae, did not change. To our knowledge, this study provides the first empirical evidence that changes in host plant quality mediated by increasing levels of CO2 can alter the outcome of interspecific competition among insect herbivores.
