[21] In aphids, the presence of a particular species of γ-3 Pseudomonadota makes the aphid relatively immune to their parasitoid wasps by killing many of the eggs. As the parasitoid's survival depends on its ability to evade the host's ...
The aphids migrate back to primary hosts in August and overwinter as eggs on weeds. In North America they are heavily parasitized by the braconid wasp Aphidius nigripes , which lays its eggs in the aphid nymphs, and these are eventually killed by the wasp larvae developing inside them.
Aphids attended by ants tend to increase the production of honeydew in smaller drops with a greater concentration of amino acids. [69] Some farming ant species gather and store the aphid eggs in their nests over the winter. In the spring, the ants carry the newly hatched aphids back to the plants.

The aphid feeds on new buds and leaves. The virus is transmitted when the aphid introduces it into the phloem of the plant. [3] In most parts of the world, there is no sexual reproductive stage in the autumn as there is in other aphid species and there are no males and no eggs. All the individuals are viviparous parthenogenetic females all year ...
