Endomeiosi inAcyrthosiphon PisumHarris (Homoptera, Aphididae)
Caryologia, 1965 RIASSUNTOL'A. ha confermato che il numero cromosomico diploide di Acyrthosiphon pisum e 2 n = 8. La coppia dei cromosomi sessuali e rappresentata dai cromosomi di lunghezza maggiore.Anche in questa specie durante l'ovogenesi partenogenetica si verifica l'endomeiosi, che presenta modalita diverse rispetto ad altri Afidi.

Biological Flora of Britain and Ireland: Cytisus scoparius*
Journal of Ecology, Volume 113, Issue 7, Page 1877-1933, July 2025.Broom is an attractive and common native plant across Britain, Ireland and most of Europe, and yet it is considered a harmful and invasive weed around the rest of the world. This is aided by broom thriving on poor dry soils, helped by using green stems for photosynthesis and having root nodules to fix nitrogen.

Entomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 724-736, July 2025.We conducted host specialization trials with three different Aphis craccivora populations. They revealed the generalist nature of the alfalfa‐origin population, which thrived when shifted to both black locust and vetch. Conversely, populations originating from black locust and vetch showed high host specialization, performing poorly when shifted to ...

Strategies used by two apterous strains of the pea aphid Acyrthosiphon pisum for passive dispersal
Biology Open, 2016 Wingless forms of aphids are relatively sedentary, and have a limited ability to migrate or disperse. However, they can drop off hosts or walk away if disturbed, or their food quality or quantity become deteriorated. Earlier, we found that the pea aphid,
