Metacommunity Ecology in a Plant–Herbivore System
The results showed that tansy–aphid metacommunity dynamics can be described mostly by the species–sorting perspective and metacomunity structure is influenced strongly by dispersal ability, strength of competitive interactions, availability of mutualistic partners and by the resident predators’ community.
Cornicle length in Macrosiphini aphids: a comparison of ecological traits
Aphids often emit cornicle droplets when attacked by predators, and it is not understood why aphid species have cornicles of different lengths.
The pea aphid complex as a model of ecological speciation
1. Host‐specialised races of plant‐feeding insects are particularly informative models in the study of ecological speciation, that is, the evolution of reproductive isolation through divergent
Ant-aphid mutualism : the influence of ants on the aphid summer cycle
The aim of this study is to investigate how the presence of ants influences settling decisions by colonizing aphids by studying the effects on aphids of being tended by ants.
Influence of host plant heterogeneity on the distribution of a birch aphid
The spatial and temporal abundance of the aphid Euceraphis betulae was investigated in relation to heterogeneity in host plant vigour and pathogenic stress and the performance of aphids feeding on vigorous and stressed foliage was examined.
An exponential growth model with decreasing r captures bottom‐up effects on the population growth of Aphis glycines Matsumura (Hemiptera: Aphididae)
1 There is ample evidence that the life history and population dynamics of aphids are closely linked to plant phenology. Based on life table studies, it has been proposed that the growth of aphid
Phenology under bottom-up control: change in host quality induces diapause in parasitic wasps
When organisms coevolve, any change in one species can affect phenotypes and ecology of the other species. Upper trophic levels have to synchronize their life-cycle to both abiotic conditions and
Influence of aphid honeydew on the foraging behaviour of Hippodamia convergens larvae
The sugary excretion of aphids (honeydew) has been proposed to serve as a prey‐associated cue for ladybird larvae to increase predator foraging efficiency.
Dispersal to predator‐free space counterweighs fecundity costs in alate aphid morphs
Short‐distance flight from patches of high population density to uninfested plants may provide temporary predator‐free space, compensating for low fecundity, but this theoretical prediction has not been explored experimentally.
Aphid colony turn‐over influences the spatial distribution of the grain aphid Sitobion avenae over the wheat growing season
This work has shown that phytophagous insects, such as crop pests living in agroecosystems, have a high ability to find and exploit new patches in temporary habitats, and their invasion is of great agricultural importance.


Seasonality and reproduction in aphids
Aphids are short-lived and occupy habitats which vary in quality in both time and space. They exploit their ephemerally nutritious habitats by rapidly producing many small offspring when conditions...
Niche relationships among species of aphids feeding on fireweed
Three species of aphids feeding on fireweed in the Rocky Mountains of Colorado, U.S.A. differ in their time of colonization of fireweed, time of maximum number of colonies, feeding position onFireweed, relationships to tending ants, life table parameters, and other life history characteristics.
Community Structure, Population Control, and Competition
Populations of producers, carnivores, and decomposers are limited by their respective resources in the classical density-dependent fashion and interspecific competition must necessarily exist among the members of each of these three trophic levels.
Competition for mutualists: aphids and ants
Evidence is presented which supports the hypothesis that competition occurs among species of aphids for the services of ants, and aphid–ant systems should be used for the study of competition for mutualists.
1. Life‐table data for 14 species of Lepidoptera are analysed by the k‐factor technique of Varley & Gradwell (1960). Two factors are shown to be of particular importance in determining fluctuations
Dispersal in Aphids, A Problem in Resource Allocation
The tendency to disperse is an adaptation that has enabled aphids to spread the chance of survival in space, and to seek out and colonize plants that are of above average quality.
The numbers and distribution of subterranean aphids and their exploitation by the ant Lasius flavus (Fabr.)
Abstract. 1. Subterranean aphids in old pasture were found to show extremely clumped distributions with about 3000 aphids (omitting first instars) per ant nest throughout the year.
The effect of temperature on the growth and reproduction of two closely related aphid species on sycamore
Abstract. 1. Egg hatch in the two species of sycamore aphid was temporally separated: the median time to hatch was 30 days later in Drepanosiphum acerinum than in D.platanoidis.
Seasonal variation in reproductive potential: a programmed feature of aphid life cycles.
In those generations showing variability an individual with a high number of ovarioles was potentially more fecund and reproduced at a greater rate than individuals with few o varioles.
Why There are So Few Species of Aphids, Especially in the Tropics
It is possible to account for the distribution and low species diversity of aphids in terms of the constraints imposed by their way of life, namely, the short period for which they can survive
