A major-effect genetic locus, ApRVII, controlling resistance against both adapted and non-adapted aphid biotypes in pea

, 2022
International audienceIn a context of reduced insecticide use, the development of cultivars resistant to insect pests is crucial for an integrated pest management. Pea (Pisum sativum) is a crop of major importance among cultivated legumes, for the supply

Polyphagous predatory rove beetles (Coleoptera: Staphylinidae) induce winged morphs in the pea aphid Acyrthosiphon pisum (Hemiptera: Aphididae)

European Journal of Entomology, 2013
A number of aphid species have been shown to produce winged dispersal morphs in the presence of natural enemies. Previous studies tested specialized aphid predators such as ladybirds or lacewing larvae.

Biology and control of currant lettuce aphid nasonovia ribisnigri [PDF]

There is a consensus that the development of successful Integrated Pest Management strategies requires a detailed understanding of pest biology. In the case of the currant lettuce aphid (Nasonovia ribisnigri), an economically important pest aphid of ...

Dynamics of copy number variation in host races of the pea aphid. [PDF]

, 2014
Copy number variation (CNV) makes a major contribution to overall genetic variation and is suspected to play an important role in adaptation. However, aside from a few model species, the extent of CNV in natural populations has seldom been investigated ...

Limited effects of the maternal rearing environment on the behaviour and fitness of an insect herbivore and its natural enemy.

PLoS ONE, 2019
The maternal rearing environment can affect offspring fitness or phenotype indirectly via 'maternal effects' and can also influence a mother's behaviour and fecundity directly.

Genome Sequence of the Pea Aphid \u3ci\u3eAcyrthosiphon pisum\u3c/i\u3e

, 2010
Aphids are important agricultural pests and also biological models for studies of insect-plant interactions, symbiosis, virus vectoring, and the developmental causes of extreme phenotypic plasticity.

ApCarE4 and ApPOD3 participate in the adaptation of pea aphids to different alfalfa varieties

Scientific Reports
The adaptability of insects to hosts has long been a focal point in the study of insect-plant interactions. The pea aphid (Acythosiphon pisum), a significant pest of numerous leguminous crops, not only inflicts direct economic losses but also ...

Pea Aphid

, 2008
Aphids have long been of interest because of their complex life cycles, environmentally induced morphologies, and importance to agriculture. However, only recently has the resulting wealth of ecological and population genetic data begun to be ...

Gene expression analysis of parthenogenetic embryonic development of the pea aphid, Acyrthosiphon pisum, suggests that aphid parthenogenesis evolved from meiotic oogenesis.

PLoS ONE, 2014
Aphids exhibit a form of phenotypic plasticity, called polyphenism, in which genetically identical females reproduce sexually during one part of the life cycle and asexually (via parthenogenesis) during the remainder of the life cycle.

Potato leafroll virus, its purification from its vector Myzus persicae

, 1967
Experiments were described on the purification of potato leafroll virus (PLRV) from its vector Myzus persicae. Preliminary experiments demonstrated that much non- viral material had to be removed from aphid macerates to obtain a pure virus preparation ...
