Intracellular symbiotes of the pea aphid, Acyrthosiphon pisum

Journal of Insect Physiology, 1973
Histological and ultrastructural studies on the mycetome of the pea aphid, Acyrthosiphon pisum, disclosed two types of symbiotes. The more common primary symbiotes were oval in shape and were found in large mycetocytes making up the bulk of the mycetome.

Study of RNA interference of HSPA1L in Acyrthosiphon pisum

John Heinrichs Scholarly & Creative Activities Day, 2023
Acyrthosiphon pisum, commonly known as pea aphids, are agricultural pests that cause billions in damage to crops, particularly Febaceae, also known as legumes. The goal of this study is to determine the relationship that exists between the concentration of dsRNA (double-stranded ribonucleic acid) and the survival of A. pisum.

Acyrthosiphon pisum . [Distribution map].

Distribution Maps of Plant Pests, 2005
Abstract A new distribution map is provided for Acyrthosiphon pisum (Harris) ( Macrosiphum pisum (Harris), M. onobrychis (Boy.)) (Hemipt., Aphididae) (Pea Aphis). Host Plants: Pea, beans and other legumes. A vector of virus diseases.

Extraordinary proliferation of microorganisms in aposymbiotic pea aphids, Acyrthosiphon pisum

Journal of Invertebrate Pathology, 2003
Aposymbiotic pea aphids, which were deprived of their intracellular symbiotic bacterium, Buchnera, exhibit growth retardation and no fecundity. High performance liquid chromatographic (HPLC) analysis revealed that these aposymbiotic aphids, when reared on broad bean plants, accumulated a large amount of histamine.

Sexual morph determination in the aphid, Acyrthosiphon pisum

Journal of Insect Physiology, 1972
Abstract The effects of two temperatures and a series of photoperiods on sexual morph determination in an aphid are examined. Photoperiodic response curves are presented and analysed. Female morph determination and male production were influenced by both these environmental factors.

Neuropeptide and neurohormone precursors in the pea aphid, Acyrthosiphon pisum

Insect Molecular Biology, 2010
Abstract Aphids respond to environmental changes by developing alternative phenotypes with differing reproductive modes. Parthenogenetic reproduction occurs in spring and summer, whereas decreasing day lengths in autumn provoke the production of sexual forms.

AGGREGATION BEHAVIOR OF PEA APHIDS, ACYRTHOSIPHON PISUM

Entomologia Experimentalis et Applicata, 1967
First and second instar pea aphid nymphs were allowed to respond in multiple choice test chambers having five parafilm feeding stations, each of which contained 20% sucrose solution. Under light conditions, the aphids assumed a negative bionomial distribution. This same phenomenon occurred in darkness, but with a lesser degree of aggregation.

Characterisation of immune responses in the pea aphid, Acyrthosiphon pisum

Journal of Insect Physiology, 2011
The innate immune system of insects provides effective defence against a range of parasites and pathogens. The pea aphid, Acyrthosiphon pisum, is a novel study system for investigating host-parasite interactions due to its complex associations with both well-characterised bacterial symbionts and a diversity of pathogens and parasites, including several

Oxidative stress links response to lead and Acyrthosiphon pisum in Pisum sativum L.

Journal of Plant Physiology, 2019
This study demonstrates the impact of lead at hormetic (0.075 mM Pb(NO3)2) and sublethal (0.5 mM Pb(NO3)2) doses on the intensity of oxidative stress in pea seedlings (Pisum sativum L. cv. 'Cysterski'). Our first objective was to determine how exposure of pea seedlings to Pb alters the plant defence responses to pea aphid (Acyrthosiphon pisum Harris ...
