Aspartate aminotransferase in the pea aphid, Acyrthosiphon pisum (Harris)
Comparative Biochemistry and Physiology, 1968Abstract 1. 1. Aspartate aminotransferase (2.6.1.1 l -aspartate: 2-oxoglutarate aminotransferase) was found to be present in the post mitochondrial supernatant fraction of homogenates of whole pea aphids. The pH optimum was observed to be 8·3. 2. 2.

A New Rickettsia from a Herbivorous Insect, the Pea Aphid Acyrthosiphon pisum (Harris)
Current Microbiology, 1996An undescribed, maternally heritable, rod-shaped bacterium (or "tertiary symbiont") was detected by microscopy in hemolymph of about half (59/122) of pea aphid [Acyrthosiphon pisum (Harris)] clones collected from widely separated locations in California.

Virology, 1979
Abstract Aphid-transmissible and non-aphid-transmissible strains of pea enation mosaic virus were compared in biological and physical properties. When separated by electrophoresis into 3.4% polyacrylamide gels both centrifugal components of aphid-transmissible strains gave rise to multiple-banding, whereas non-aphid-transmissible strains migrated as ...

Linoleic acid biosynthesis in the pea aphid, Acyrthosiphon pisum (Harris)
Archives of Insect Biochemistry and Physiology, 1986AbstractThe pea aphid Acyrthosiphon pisum (Harris) incorporated [1‐14C]acetate into a phospholipid dienoic fatty acid in a time‐dependent manner. In 2‐h incubations, the incorporation of radioactivity into the 18:2 fraction was minimal, whereas after 45 h 18:2 was the major fatty acid labeled.

Deterrence and Toxicity of Plant Saponins for the Pea Aphid Acyrthosiphon Pisum Harris
Journal of Chemical Ecology, 2007Plant saponins are widely distributed among plants and have a wide range of biological properties. Three alfalfa saponins - zanhic acid tridesmoside, 3GlcA, 28AraRhaXyl medicagenic acid glycoside, and 3GlcA, 28AraRha medicagenic acid glycoside - were tested for their settling inhibition effects on feeding behavior of the aphid Acyrthosiphon pisum using

The fate of pea enation mosaic virus in its pea aphid vector, Acyrthosiphon pisum (Harris)
Virology, 1972Abstract The fate of pea enation mosaic virus (PEMV) in its primary vector the pea aphid, Acyrthosiphon pisum (Harris), was studied by ultrathin sectioning and conventional transmission electron microscopy. PEMV virions were highly concentrated in the lumen of the midgut and hindgut, and also invaded a variety of tissues in the vector. Virions were

Studies on the dispersal behaviour of apterous pea aphids acyrthosiphon pisum (Harris)
1978The dispersal behaviour of apterous pea aphids, Acyrthosipon pi sum (Harris) was studied in the laboratory and field. In the laboratory, aphids exhibited two types of behaviour while on the ground, after dropping from plants in response to predators.

Biotypes of Pea Aphid Acyrthosiphon pisum (Harris) in Relation to Alfalfa Clones
The Canadian Entomologist, 1965AbstractTen alfalfa clones, Medicago sativa L., were tested at 60°, 70° and 80° F. in Kansas and Quebec for resistance to pea aphid biotypes, Acyrthosiphon pisum (Harris), originating in the respective areas.The resistance of the clones at the three temperatures varied differentially at the two locations.
