Micromorphology of the model species pea aphid Acyrthosiphon pisum (Hemiptera, Aphididae) with special emphasis on the sensilla structure

open access: yesThe European Zoological Journal, 2020
The pea aphid complex [Acyrthosiphon pisum (Harris 1776)] (Hemiptera, Aphididae), listed among the 14 aphid species of the greatest economic importance, is a globally distributed key pest of pulse crops.

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

open access: yesInsect Molecular Biology, Volume 35, Issue 3, Page 217-231, June 2026.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

THE PHENOLOGY AND DISTRIBUTION OF APHIDS IN CALIFORNIA ALFALFA AS MODIFIED BY LADYBIRD BEETLE PREDATION (COLEOPTERA: COCCINELLIDAE) [PDF]

open access: yes, 2017
The phenologies and distributions of pea aphid (Acyrthosiphon pisum (Harris)), blue alfalfa aphid (A. kondoi (Shinji)), and spotted alfalfa aphid (Therioaphis maculata (Buckton)) were intensively studied in California alfalfa.

RNAi efficiency, systemic properties, and novel delivery methods for pest insect control : what we know so far [PDF]

open access: yes, 2016
In recent years, the research on the potential of using RNA interference (RNAi) to suppress crop pests has made an outstanding growth. However, given the variability of RNAi efficiency that is observed in many insects, the development of novel approaches

The impact of individual ladybirds (Coccinella septempunctata, Coleoptera: Coccinellidae) on aphid colonies

open access: yesEuropean Journal of Entomology, 2000
Pea aphids (Acyrthosiphon pisum) have been reported to produce winged offspring in the presence of predatory ladybirds. These offspring may leave host plants by flight after they have developed into winged adults.

Transcriptomic and DNA Methylation Profiles of Alternative Aphid Morphs and Genotypes

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
Graph showing the correlation between differentially expressed genes and differentially methylated genes. There is no correlation between gene expression and DNA methylation level in pea aphid polyphenism. ABSTRACT Pea aphids can develop alternative morphs when exposed to stressful conditions, showing differences between genotypes in their stress ...

Combining next-generation sequencing strategies for rapid molecular resource development from an invasive aphid species, Aphis glycines. [PDF]

open access: yesPLoS ONE, 2010
Aphids are one of the most important insect taxa in terms of ecology, evolutionary biology, genetics and genomics, and interactions with endosymbionts. Additionally, many aphids are serious pest species of agricultural and horticultural plants.

The Australian Crop Mirid, Sidnia kinbergi Stål (Hemiptera: Miridae): Lifecycle, Agricultural Impact and Management

open access: yesAustral Entomology, Volume 65, Issue 2, May 2026.
ABSTRACT The Australian Crop Mirid (ACM), Sidnia kinbergi Stål (Hemiptera: Miridae), is highly polyphagous and is endemic to Australia. It is widely distributed across Australia and New Zealand and feeds on a wide range of agricultural crops. ACM has traditionally been a pest of forage crops and legumes but has recently emerged as a key pest of several

Density dependence of the alarm pheromone effect in pea aphids, Acyrthosiphon pisum (Sternorrhyncha: Aphididae)

open access: yesEuropean Journal of Entomology, 2007
The aphid alarm pheromone is known to trigger wing induction in pea aphids (Acyrthosiphon pisum). In reaction to alarm pheromone, aphids drop off the plant or walk away.
