The Efficacy of Biological Control for the Suppression of the Pea Aphid (Acyrthosiphon Pisum): Does the Resistance of Alfalfa Cultivars Matter? [PDF]

Insects, 2022
The pea aphid, Acyrthosiphon pisum Harris, is a major pest of alfalfa in northwestern China. However, the roles of different groups of natural enemies in combination with aphid-resistant cultivars in the suppression of the pea aphid have not been ...

Transcriptomic and Metatranscriptomic Analyses Provide New Insights into the Response of the Pea Aphid Acyrthosiphon pisum (Hemiptera: Aphididae) to Acetamiprid [PDF]

Insects
Acetamiprid is a broad-spectrum neonicotinoid insecticide used in agriculture to control aphids. While recent studies have documented resistance to acetamiprid in several aphid species, the underlying mechanisms are still not fully understood.

Self-Recognition and Allorecognition Mechanisms Exert a Significant Influence on the Sex Allocation Patterns of the Pea Aphid [PDF]

Insects
The mechanism controlling sex allocation in the pea aphid, Acyrthosiphon pisum (Harris), remains a crucial yet unresolved issue in the field of evolutionary ecology. This study aims to assess the influence of the presence of both self and non-self clones,

Role of nitrogen content of pea (Pisum sativum L.) on pea aphid (Acyrthosiphon pisum Harris) establishment

Caspian Journal of Environmental Sciences, 2008
The leaf nitrogen content is generally accepted as an indicator of food quality and as a factor affecting host selection by phytophagous insects. The alate pea aphids (Acyrthosiphon pisum Harris, Aphididae) were given a choice among non-nodulated pea ...

EFFICIENCY OF TRANSMISSION PEA ENATION MOSAIC VIRUS (PEMV) BY THE PEA APHID IN DAKHLIA GOVERNORATE, EGYPT [PDF]

Journal of Productivity and Development, 2022
The pea aphid Acyrthosiphon pisum (Harris) is considered as vector for numerous plant viruses, including Pea enation mosaic virus (PEMV)). Experiments confirmed the ability of A. pisum adult to acquire and transmit the virus to pea plantations in Dakhlia

The Genetics of Host Plant Acceptance in Pea Aphids. [PDF]

Mol Ecol
ABSTRACT The evolution of host‐associated sympatric populations in phytophagous insects (so called “host races”) connects adaptive divergence to barriers to gene flow. Pea aphid (Acyrthosiphon pisum) host races specialise on legume species, and because host plant choice leads to assortative mating, the genetic basis of host plant acceptance is key to ...

How a Melanism Mutant Responds to Different Temperatures: A Case Study in Ladybird Beetle <i>Harmonia axyridis</i> Demonstrating Thermal-Induced Phenotypic Plasticity. [PDF]

Ecol Evol
ml, inherited in a Mendelian autosomal recessive manner, is a novel melanism mutant of Harmonia axyridis. When compared to wt, ml exhibited vastly smaller changes in the occurrence frequencies of dark spots on both the dorsal cuticles of pupa and elytra in response to thermal variations. ml had very high melanin level even at 32.5°C and showed a higher
