“…We can answer this question, in part, using three comparable published studies that examined the impacts of environmental change on interactions between lucerne and the pea aphid. One experiment was replicated using multiple chambers (Johnson et al, 2014 ), one replicated using multiple experimental runs (Ryalls et al, 2015 ) and one adopted the chamber swapping approach (Ryalls, 2016 ). The first of these only examined e[CO 2 ], whereas the other two experiments also included eT.…”

Data from three experiments using replication with multiple chambers (Johnson et al, 2014 ) and multiple experimental runs (Ryalls et al, 2015 ) compared with the “chamber swapping” approach (Ryalls, 2016 ). All experiments used the same cultivar (Sequel) and similar levels of [CO 2 ] (400 vs. 600–640 ppm) and temperature (25–26 vs. 30°C).…”

Aphids are herbivores carrying the status of major pests for crops and ornamental plants. The many specific biological features of aphids allow them to survive unfavorable environmental conditions. As for other insects, a predominant strategy for aphids surviving winter, is laying diapausing eggs. During diapause, the expression of development may vary between species. Most of the insects stop growing during diapause; however, there is limited information about this process. We immunostained the embryos of aphids in order to detect cell division during diapause. Here, for the first time, we present that two species of aphids belonging to Cinara grow and develop throughout the duration of the winter diapause. Our results showed that the “resting stage” does not occur in embryos of these aphid species. The embryo of C. cupressi and C. juniperi undergoes a type of diapause, with slow growth. It seems that this feature is conducive to the rapid development of embryos in the egg, which may be another specific feature for aphid biology of overwintering.

“…Aphid numbers may also be influenced by land‐use: indeed, it seems that geographical patterns of aphid abundance are related to regional landscape features, including the proportion of a given crop in a given area (Cocu et al ., , b). However, besides theoretical models (Ciss et al ., ), little is known about the relationship between aphid population characteristics and the area of crop, notably at a large scale, and land‐use data are needed to improve predictions of global change impacts (Ryalls & Harrington, ). Because so few studies have considered both parameters at once (Cocu et al ., ; Wang et al ., ), the respective influence of climatic and land‐use factors on aphid spatiotemporal population dynamics is poorly documented.…”

Relative importance of long‐term changes in climate and land‐use on the phenology and abundance of legume crop specialist and generalist aphids

Insect populations are prone to respond to global changes through shifts in phenology, distribution and abundance. However, global changes cover several factors such as climate and land-use, the relative importance of these being largely unknown. Here, we aim at disentangling the effects of climate, land-use, and geographical drivers on aphid abundance and phenology in France, at a regional scale and over the last 40 years. We used aerial data obtained from suction traps between 1978 and 2015 on five aphid species varying in their degree of specialization to legumes, along with climate, legume crop area and geographical data. Effects of environmental and geographical variables on aphid annual abundance and spring migration dates were analyzed using generalized linear mixed models. We found that within the last four decades, aphids have advanced their spring migration by a month, mostly due to the increase in temperature early in the year, and their abundance decreased by half on average, presumably in response to a combination of factors. The influence of legume crop area decreased with the degree of specialization of the aphid species to such crops. The effect of geographical variation was high even when controlling for environmental variables, suggesting that many other spatially structured processes act on aphid population characteristics. Multifactorial analyses helped to partition the effects of different global change drivers. Climate and land-use changes have strong effects on aphid populations, with important implications for future agriculture. Additionally, trait-based response variation could have major consequences at the community scale.
