Evaluating climate change scenarios on global pea aphid habitat suitability using species distribution models

open access: yesClimate Change Ecology
The global threat of invasive alien species (IAS) being introduced into new habitats is concerning, particularly in agricultural crops as invasive insect species are continuing to expand their distribution through anthropogenic activities and climate ...

Dopamine mediates the pea aphid wing plasticity. [PDF]

open access: yesBiol Lett, 2023
Many organisms exhibit phenotypic plasticity, in which developmental processes result in different phenotypes depending on their environmental context. Here we focus on the molecular mechanisms underlying that environmental response. Pea aphids ( Acyrthosiphon pisum ) exhibit a wing dimorphism, in which pea aphid ...

The circadian and photoperiodic clock of the pea aphid. [PDF]

open access: yesJ Comp Physiol A Neuroethol Sens Neural Behav Physiol, 2023
AbstractThe pea aphid, Acyrthosiphon pisum, is a paradigmatic photoperiodic species that exhibits a remarkable annual life cycle, which is tightly coupled to the seasonal changes in day length. During spring and summer, characterised by longer days, aphid populations consist exclusively of viviparous females that reproduce parthenogenetically.

Effect of selenium on alleviating oxidative stress in pea leaves caused by pea aphid feeding

open access: yesJournal of Plant Protection Research, 2021
The aim of this study was to evaluate the antioxidant effect of selenium in Pisum sativum L. plants pre-treated with sodium selenite or sodium selenate at a concentration of 10 and 20 μM, and then colonized by pea aphid Acyrthosiphon pisum (Harris). It

Transcriptomic basis of sex loss in the pea aphid. [PDF]

open access: yesBMC Genomics
Abstract Background Transitions from sexual to asexual reproduction are common in eukaryotes, but the underlying mechanisms remain poorly known. The pea aphid—Acyrthosiphon pisum—exhibits reproductive polymorphism, with cyclical parthenogenetic and obligate parthenogenetic lineages, offering an opportunity to decipher ...

Functional Analysis of Amino Acid Transporter Genes ACYPI000536 and ACYPI004320 in Acyrthosiphon pisum

open access: yesInsects, 2023
In recent years, pea aphids have become major pests of alfalfa. Our previous study found that “Gannong 5” is a highly aphid-resistant alfalfa variety and that “Lie Renhe” is a susceptible one.

To feed or not to feed: plant factors located in the epidermis, mesophyll, and sieve elements influence pea aphid's ability to feed on legume species. [PDF]

open access: yesPLoS ONE, 2013
The pea aphid (Acyrthosiphon pisum Harris), a legume specialist, encompasses at least 11 genetically distinct sympatric host races. Each host race shows a preference for a certain legume species.

Evaluating Vector-Virus-Yield Interactions for Peas and Lentils under Climatic Variability: A Limited Dependent Variable Analysis

open access: yesJournal of Agricultural and Resource Economics, 2011
This study examines the effects of climatic conditions on interactions among pea and lentil yields, pea aphid Acyrthosiphon pisum (Harris) infestations, and outbreaks of PEMV (Pea enation mosaic) and BLRV (Bean leaf roll) viruses in the Palouse region of

Seasonal dynamics and entomophthoralean infection of the pea aphid, Acyrthosiphon pisum Harris

open access: yesPlant Protection Science, 2001
The seasonal dynamics of the pea aphid, Acyrthosiphon pisum Harris, and entomopathogenic fungi from the order Entomophthorales attacking the aphid were analysed in alfalfa and field pea crops during the growing seasons of 1998 and 1999 at Nitra-Malanta ...
