A comparison of the amino acid profiles of the pea aphid, Acyrthosiphon pisum, and the social aphid species, Pemphigus spyrothecae (Hemiptera: Aphididae)

open access: yesEuropean Journal of Entomology, 2010
The relative proportions of free amino acids as well as the amino acid compositions of hydrolysed unprecipitated peptides and hydrolysed whole carcasses were quantified for two aphid species: the gall-dwelling social aphid Pemphigus spyrothecae and the ...

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

Acyrthosiphon pisum AQP2: A multifunctional insect aquaglyceroporin

open access: yesBiochimica et Biophysica Acta (BBA) - Biomembranes, 2012
Annotation of the recently sequenced genome of the pea aphid (Acyrthosiphon pisum) identified a gene ApAQP2 (ACYPI009194, Gene ID: 100168499) with homology to the Major Intrinsic Protein/aquaporin superfamily of membrane channel proteins. Phylogenetic analysis suggests that ApAQP2 is a member of an insect-specific clade of this superfamily.

Increased xylem ingestion and decreased phloem ingestion in the aphid Acyrthosiphon pisum (Hemiptera: Aphididae) parasitised by Aphidius ervi (Hymenoptera: Braconidae)

open access: yesEuropean Journal of Entomology, 2006
The effects of parasitisation by Aphidius ervi on the feeding behaviour of the aphid Acyrthosiphon pisum were studied. There was progressive increase in the time devoted to xylem ingestion (G waveform) and concomitant decrease in time devoted to phloem ...

Fungal Pathogens Infecting Soybean Aphid and Aphids on Other Crops Grown in Soybean Production Areas of Michigan [PDF]

open access: yes, 2018
Seasonal prevalence of fungal pathogens infecting soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), was assessed from 2004 to 2006 in two Michigan soybean production areas. In 2005 and 2006 field-collected soybean aphids were incubated, and
