J. Sandstrom ; N. Moran | 1999Aphids harbour intracellular symbionts (Buchnera) that provide their host with amino acids present in low amounts in their diet, phloem sap. To find out the extent to which aphids depend on their symbionts for synthesis of individual essential a[...]![]()

B. Sabater ; R. Vanham ; D. Martineztorres ; F. Silva ; A. Latorre ; A. Moya | 2001Aphids maintain an obligate, endosymbiotic association with Buchnera sp., a bacterium closely related to Escherichia coli. Bacteria are housed in specialized cells of organ-like structures called bacteriomes in the hemocoel of the aphid and are [...]![]()

A. Dixon ; P. Kindlmann ; V. Jarosik | 19951. The distribution of the body sizes of British aphids is right-skewed on a logarithmic axis, as in other taxa, Over the size range 2-5 mm there is a marked decrease in numbers of species with increase in size, which on a log log scale has an e[...]![]()

The application of the concept of committed phloem ingestion (CPI) of aphids was studied for different aphid species feeding on resistant and susceptible plants. Greenbugs, Schizaphis graminum (Rondani) (biotype E), were monitored electronically[...]![]()

A. Givovich ; H. Niemeyer | 1995Feeding behaviour of five species of cereal aphids in wheat seedlings differing in hydroxamic acid (Hx) levels, was monitored via electrical penetration graphs (EPG). Aphid species could be grouped as sensitive to the feeding deterrent effect of[...]![]()

B. Stadler ; W. Weisser ; A. Houston | 19941. This paper investigates the influence of life-history traits on the defence reactions shown by aphids. In particular, we combine experimental data on the reproductive biology of the monophagous aphid Uroleucon jaceae (L.) feeding on Centaurea[...]![]()

E. Turak ; R. Talent ; P. Sunnucks ; D. Hales | 1998Chromosomal races of the aphid Sitobion miscanthi (Takahashi), and a closely-related species S. near fragariae (Aphididae: Macrosiphini) show seasonal differences in abundance in eastern Australia. We tested whether this was related to differenc[...]![]()

P. Debarro ; T. Sherratt ; S. Wratten ; N. Maclean | 1994The role of DNA fingerprinting as a tool for studying cereal aphid populations along with the principals behind fingerprinting and the process of obtaining fingerprints using the multilocus probe, P-32 labelled (GATA)4 are discussed. The success[...]![]()

This paper reviews the evidence for the fundatrix specialization hypothesis and attempts to quantify the relative advantage of host alternation and define the conditions favouring the evolution of this way of life. Contrary to the predictions of[...]
