“…This is consistent with a study using the same insect-plant model Trębicki et al (2016), as well as others on different aphids and their predators (Awmack et al, 2004;Boullis et al, 2018;Jiang et al, 2018). However, a decrease in aphid development time was observed under eCO 2 in Brevicoryne brassicae when reared on ornamental cabbages (Amiri-Jami et al, 2012). We found that greater N application rates did not significantly affect aphid development, duration of the period from birth to the onset of reproduction or mean generation time.…”

The rise in atmospheric carbon dioxide (CO2) generally increases wheat biomass and grain yield but decreases its nutritional value. This, in turn, can alter the metabolic rates, development, and performance of insect pests feeding on the crop. However, it is unclear how elevated CO2 (eCO2) and nitrogen (N) input affect insect pest biology through changes in wheat growth and tissue N content. We investigated the effect of three different N application rates (low, medium, and high) and two CO2 levels (ambient and elevated) on wheat growth and quality and the development and performance of the bird cherry-oat aphid, a major cereal pest worldwide, under controlled environmental conditions. We found that eCO2 significantly decreased total aphid fecundity and wheat N content by 22 and 39%, respectively, when compared to ambient CO2 (aCO2). Greater N application significantly increased total aphid fecundity and plant N content but did not offset the effects of eCO2. Our findings provide important information on aphid threats under future CO2 conditions, as the heavy infestation of the bird cherry-oat aphid is detrimental to wheat grain yield and quality.

“…(2010) observed a non-significant effect of e CO 2 on ‘ r m ’ for cotton boll worms. In case of aphids, e CO 2 influenced performance by producing an increase of ‘ r m ’, ‘λ’, ‘ T ’ and ‘DT’ ( Amirijami et al. 2012 ).…”

Predicted increase in temperature and atmospheric CO 2 concentration will influence the growth of crop plants and phytophagous insects. The present study, conducted at the Central Research Institute for Dryland Agriculture, Hyderabad, India, aimed at 1) construction of life tables at six constant temperatures viz ., 20, 25, 27, 30, 33, and 35 ± 0.5°C for Spodoptera litura (Fabricius) (Noctuidae: Lepidoptera) reared on sunflower ( Helianthus annus L.) grown under ambient and elevated CO 2 ( e CO 2 ) (550 ppm) concentration in open top chambers and 2) prediction of the pest status in near future (NF) and distant future (DF) climate change scenarios at major sunflower growing locations of India. Significantly lower leaf nitrogen, higher carbon and higher relative proportion of carbon to nitrogen (C:N) were observed in sunflower foliage grown under e CO 2 over ambient. Feeding trials conducted on sunflower foliage obtained from two CO 2 conditions showed that the developmental time of S. litura (Egg to adult) declined with increase in temperature and was more evident at e CO 2 . Finite (λ) and intrinsic rates of increase ( rm ), net reproductive rate ( Ro ), mean generation time, (T) and doubling time (DT) of S. litura increased significantly with temperature up to 27–30°C and declined with further increase in temperature. Reduction of ‘ T ’ was observed from maximum value of 58 d at 20°C to minimum of 24.9 d at 35°C. The DT of population was higher (5.88 d) at 20°C and lower (3.05 d) at 30°C temperature of e CO 2 . The data on these life table parameters were plotted against temperature and two nonlinear models were developed separately for each of the CO 2 conditions for predicting the pest scenarios. The NF and DF scenarios temperature data of four sunflower growing locations in India is based on PRECIS A1B emission scenario. It was predicted that increased ‘ rm ’, ‘λ’, and ‘ Ro ’ and reduced ‘ T ’ would occur during NF and DF scenario over present period at all locations. The present results indicate that temperature and CO 2 are vital in influencing the population growth of S. litura and pest incidence may possibly be higher in the future.

“…The parameters of a two‐sex life table, age‐specific survival rates (l x ), and age‐specific fecundity (m x ) were calculated. The intrinsic rate of increase (r m ), a compound parameter reflecting the combined effect of factors such as growth, development, and fecundity of the whole population, was estimated by using the iterative bisection method from the Euler‐Lotka formula:

{false\sum}_{x = 0}^{\infty} e^{- r_{m} (x + 1)} l_{x} m_{x} = 1,

with age indexed from 0 (Amiri‐Jami et al., ). The net productive rate (R 0 ), mean generation time (T), population doubling time (DT), and finite rate of increase (λ) were calculated by the following equations:

{normalR}_{0} = {false\sum}_{x = 1}^{\infty} l_{x} m_{x},

T = In {normalR}_{0} / {normalr}_{normalm},

DT = In 2 / {normalr}_{normalm},

and

λ = {normale}^{r_{m}} .

“…The decreased plant nutritional quality may increase consumption rates, mortality, development, and fecundity, and reduce the fitness of insect herbivores (Ge et al., ; Lindroth, ; Robinson et al., ). For example, the fecundity of the grain aphid, Sitobion avenae (Fabricius), was higher in elevated CO 2 , and the pre‐reproduction period was shortened (Awmack et al., ), whereas the cabbage aphid, Brevicoryne brassicae (L.), had a shorter pre‐reproduction period but fecundity was not affected (Amiri‐Jami et al., ). Another hemipteran, Neophilaenus lineatus (L.), responded to elevated CO 2 with a lower survival rate and extended development time; however, its fecundity was not affected (Brooks & Whittaker, ).…”

The objective of this study was to determine how elevated CO2 impacts on life‐history traits and life table parameters in three successive generations of invasive species Frankliniella occidentalis (Pergande) (Thysanoptera: Thripidae) and its related native species, Frankliniella intonsa (Pergande), fed with kidney bean leaves grown in ambient CO2. The oviposition period, sex ratio, net reproductive rate (R0), intrinsic rate of increase (rm), and finite rate of increase (λ) of F. occidentalis increased in elevated CO2, and larval duration, survival rate, mean generation time (T), and population doubling time (DT) decreased. For F. intonsa, larval duration, survival rate, oviposition period, longevity of female adults, R0, rm, and λ decreased in elevated CO2, whereas sex ratio, T, and DT increased. These results indicated that the effects of elevated CO2 would be beneficial to F. occidentalis, whereas it would be detrimental to F. intonsa. However, the effects of elevated CO2 on F. occidentalis and F. intonsa differed over generations. In elevated CO2, larval duration, survival rate, oviposition period, sex ratio, rm, and λ of F. occidentalis increased linearly through successive generations, whereas T and DT decreased linearly, which suggested that the effects of elevated CO2 on F. occidentalis would be slowly accentuated over time. For F. intonsa, larval duration, survival rate, oviposition period, rm, and λ decreased linearly over generations, whereas sex ratio, T, and DT increased linearly. This indicated that the effects of elevated CO2 on F. intonsa would slowly accentuate over time. We conclude that F. occidentalis would be more adapted to elevated CO2 than F. intonsa.
