Genetic Control of Contagious Asexuality in the Pea Aphid

PLoS Genetics, 2014
Although evolutionary transitions from sexual to asexual reproduction are frequent in eukaryotes, the genetic bases of such shifts toward asexuality remain largely unknown. We addressed this issue in an aphid species where both sexual and obligate asexual lineages coexist in natural populations.

Large-scale gene discovery in the pea aphid Acyrthosiphon pisum (Hemiptera)

, 2006
Aphids are the leading pests in agricultural crops. A large-scale sequencing of 40,904 ESTs from the pea aphid Acyrthosiphon pisum was carried out to define a catalog of 12,082 unique transcripts.

Genome Sequence of the Pea Aphid Acyrthosiphon pisum

, 2012
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.

Untargeted Metabolomics Approach Reveals Differences in Host Plant Chemistry Before and After Infestation With Different Pea Aphid Host Races

Frontiers in Plant Science, 2019
The pea aphid (Acyrthosiphon pisum), a phloem-sucking insect, has undergone a rapid radiation together with the domestication and anthropogenic range expansion of several of its legume host plants.

Experimental evidence reveals that vector host preference and performance across host plants is not altered by vector-borne plant viruses

Frontiers in Ecology and Evolution, 2023
Many plant pathogens are transmitted by generalist insects that move between host species, and vector preference and performance on different hosts affects pathogen transmission.

The effect of within-crop habitat manipulations on the conservation biological control of aphids in field-grown lettuce [PDF]

, 2011
Within-crop habitat manipulations have the potential to increase the biological control of pests in horticultural field crops. Wildflower strips have been shown to increase the abundance of natural enemies, but there is little evidence to date of an ...

EMS Mutagenesis in the Pea AphidAcyrthosiphon pisum [PDF]

G3 Genes|Genomes|Genetics, 2014
AbstractIn aphids, clonal individuals can show distinct morphologic traits in response to environmental cues. Such phenotypic plasticity cannot be studied with classical genetic model organisms such as Caenorhabditis elegans or Drosophila melanogaster. The genetic basis of this biological process remain unknown, as mutations affecting this process are ...

Two Sphingomonas species modify the productivity and the susceptibility of Pisum sativum to pea aphid, Acyrthosiphon pisum

Plant Stress
Aphids are major pests of field crops, and their control still largely relies on chemical insecticides, which have significant ecological and health drawbacks.

Effects of timed LED regimes on tomato plant traits, performance of two‐spotted spider mites, and predatory mites (Phytoseiulus persimilis)

Pest Management Science, Volume 81, Issue 4, Page 2300-2311, April 2025.
Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...
