“…At present, these models lack sufÞcient information to predict biomass losses by insects and pathogens. Our study shows S. flava performance on the biofuel hosts and previous studies have examined the inßuence of abiotic factors on the pest (Miskimen 1970, Oliveira et al 2009, Auad et al 2012). These may be useful in future modeling efforts.…”

Among the insects reported in biofuel crops, the yellow sugarcane aphid, Sipha flava (Forbes), is a potential pest of giant miscanthus, Miscanthus x giganteus Greef et Deu ex Hodkinson et Renvoize (M x g) and energy cane 'L79-1002', Saccharum spp. L. We studied the biology of S. flava on M x g and energy cane and estimated the development period, fecundity, longevity, intrinsic rate of increase, doubling time, reproductive value, and survivorship curves. To demonstrate the host suitability in a susceptible species, we studied the aphid life table on sorghum 'PL 18200,' Sorghum bicolor (L.) Moench. Life-table information was recorded under greenhouse conditions on the host plants. Our results suggested that both M x g and energy cane are suitable hosts for S. flava. We observed similar aphid development period on both hosts. Life-table estimates including longevity and fecundity suggested that M x g is a more suitable host for the aphid than energy cane. The intrinsic rate of increase for S. flava was lower on energy cane (0.231) than on M x g (0.258).

“…Insect biology could be directly affected by constant and ßuctuating temperature and indirectly affected by elevated CO 2 through altering host plant biochemistry and metabolism, which leads to the changes in chemical composition (Coviella and Trumble 1999, Hunter 2001, Stiling and Cornelissen 2007, Auad et al 2012. But there are also reports showing that insect herbivores could be inßuenced by CO 2 in their respiration and behavior (Abrell et al 2005, Wu et al 2006, the underlying mechanisms of aphid performance under the four different environment conditions shown in this study could be further examined in detail in future studies.…”

Changes in Life History Parameters of Rhopalosiphum maidis (Homoptera: Aphididae) Under Four Different Elevated Temperature and CO2 Combinations

et al. 2014

Biological characteristics of corn leaf aphid, Rhopalosiphum maidis (Fitch), on barley, Hordeum vulgare L., were examined for two generations under four different elevated temperature and CO2 combinations. The developmental duration for each life stage was significantly reduced under the elevated temperature (+4 degrees C). The elevated CO2 (700-750 microl/liter) reduced only the development time of fourth-instar nymph. The overall duration of nymphal stage was reduced in the second generation. Thus, the temperature was the dominant factor to development duration of corn leaf aphid. The fecundity of corn leaf aphid was significantly increased under the elevated temperature and CO2, as well as in the later generation. Elevated temperature and CO2 increased the number of alate production, which may enhance the aphid migration or dispersal and the spread of plant viruses. Corn leaf aphid had the highest intrinsic rate of increase under the elevated temperature and CO2 combination in the second generation. These results indicate that the combined effects of both elevated temperature and CO2 on aphid biology may exacerbate aphid damage on barley under the climate change in accompany with elevated temperature and CO2 level.

“…This demonstrates the importance of considering different host varieties when studying the effects of climate change. Additionally, future CO 2 concentrations are likely to be accompanied by elevated temperatures and, although a number of studies have observed the effect of eCO 2 on aphid populations, the combination of eT and eCO 2 has received little focus (Newman, ; Himanen et al , ; Auad et al , ). To predict the effects of eCO 2 and eT on lucerne resistance to aphids, it is necessary to understand how these abiotic factors influence lucerne nutrition and defence, including what nutritional and defensive properties affect resistance, of which little is known at present.…”

1 Lucerne or alfalfa Medicago sativa is the most important temperate forage legume worldwide. Only one or two varieties of lucerne were grown in the U.S.A. and Australia (the two leading exporters of lucerne) before the late 1950s and late 1970s, respectively. These dates coincided with the arrival of aphid species, which devastated lucerne stands and prompted the development of aphid resistant cultivars. 2 Lucerne-feeding aphids, including bluegreen aphids Acyrthosiphon kondoi , pea aphids Acyrthosiphon pisum, spotted alfalfa aphids Therioaphis trifolii maculata and cowpea aphids Aphis craccivora, however, still present significant risks for the lucerne industry worldwide and account for 25% of global production losses. Moreover, increased production costs, negative environmental effects and emerging aphid resistance to insecticide applications have led to a narrowing of management options against lucerne aphids. 3 Understanding lucerne aphid biology and trophic ecology will be needed to develop future management practices, including biological control. We review and synthesize research on the four lucerne aphid species, focussing on cultivar resistance and their interactions with other organisms, including predators, parasitoids, entomopathogens and bacterial symbionts. The effects of global climate change are considered, with a particular emphasis on the potential for compromised aphid resistance in lucerne cultivars under future climates. 4 We conclude by identifying future research questions and perspectives for the sustainable management of lucerne aphids. These include the characterization of plant secondary metabolites associated with natural enemy recruitment, an understanding of the role of endosymbionts in cultivar resistance and a better comprehension of multi-trophic interactions of lucerne aphids, both with other herbivores and higher trophic groups.
