Linnaeus, though where he got it and why he applied it to the plant louse are mysteries.

Other macronutrients have been implicated in aphid success.
Aggressive mimicry coexists with mutualism in an aphid.
Pathogen dose was positively related to aphid reproduction.
Less susceptible to aphid damage than Viburnum opulus.
Transamination predicted based onthe presence of aphid genes.
The most effective of the commercial aphid predators is the aphid midge, which is a tiny fly (Aphidoletes).
This endoparasitoid consumes the aphid and then emerges from an aphid mummy as an adult.
Aphid consumption was measured by enzyme-linked immunosorbent assays (ELISA) of beetle gut contents, using an aphid-specific monoclonal antibody.
Lacewings, lady beetles, hover fly larvae, and parasitized aphid mummies are almost always present in aphid colonies.
Indicates aphid species reported to consistently transmit BYDV variants in trials using a single aphid.
