We examined the chromosome set of the aphid species Sitobion avenae, Schizaphis graminum and Methopolophium dirhodum by means of conventional staining and C, NOR, AluI and HaeIII banding methods.…
LONGEVITY, FECUNDITY AND EMBRYOGENESIS IN BRAZILIAN APHIDS'
- V. E. R. D. Celis, D. N. Gassen, V. Valente, Alice Kalisz de Oliveira
When the fecundily/longevity ratio was compared it was concluded that S. graminuni was dangerous lo wheal, and BR-35 wheal strain was most susceptible to aphid control.

Study on three species of wheat aphids (Homoptera: Aphididae) in Río Grande do Sul, Brazil
The most important morphological characteristics of aphids are reported, designed for use with specimens on microscope sudes and provide a simple identification key useful to classify multispecific infestations, as a contribution to biological control programs.
