The complete mitochondrial genome of Paracolopha morrisoni (Baker, 1919) (Hemiptera: Aphididae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
We have determined the mitochondrial genome of Paracolopha morrisoni (Baker, 1919), a gall-forming aphid collected from Korea. The circular mitogenome of Paracolopha morrisoni is 16,330 bp long including 13 protein-coding genes, 2 ribosomal RNA genes, 22

Effect of aphid abundance and urbanization on the abundance of Harmonia axyridis (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2018
The factors that affect the local distribution of the invasive Harmonia axyridis are not yet completely resolved. Hypotheses predicting positive and independent effects of prey abundance and degree of urbanization on the adult abundance of this species ...

Contribution of awns and hairy glumes in spring wheat to resistance against wheat midge, Sitodiplosis mosellana

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 781-793, July 2025.
Wheat morphological traits had no consistent impact on Sitodiplosis mosellana oviposition. Differences in the number of eggs among doubled haploid wheat lines were not associated with the presence (A+) or absence (A−) of awns, or the presence (H+) or absence (H−) of hairs in controlled laboratory experiments and field trials.

Characterization and phylogenetic analysis of the complete mitochondrial genome of Aphis spiraecola (Hemiptera: Aphididae)

open access: yesMitochondrial DNA. Part B. Resources, 2019
Aphis spiraecola is an important pest of citrus and transmits a number of plant viruses. Here, we sequenced and annotated the complete mitochondrial genome (mitogenome) of A. spiraecola.

Feeding site location in birch aphids (Sternorrhyncha: Aphididae): The simplicity and reliability of cues

open access: yesEuropean Journal of Entomology, 2000
To establish the importance of different cues for feeding site location in aphids, two birch-feeding species were given access to leaves that were either orientated normally or inverted.

Effect of Pest Control Strategies on Arthropod Pests of Apple in Europe: A Meta‐Analysis

open access: yesJournal of Applied Entomology, Volume 149, Issue 6, Page 957-987, July 2025.
ABSTRACT Apple (Malus domestica Borkh.) is a major fruit crop in Europe. More than 200 phytophagous arthropod species thrive in European apple orchards, several of which are economically important pests. Due to the pest pressure on apple production, consumer demand for residue‐free products and current policies to make food production in the European ...

Tri-trophic interaction involving host plants, black legume aphid, Aphis craccivora (Hemiptera: Aphididae) and the predator, Cheilomenes sexmaculata (Coleoptera: Coccinellidae)

open access: yesEuropean Journal of Entomology, 2016
Interactions involving host plants (cowpea, groundnut, cotton, sunflower, greengram, blackgram) an insect herbivore, black legume aphid Aphis craccivora Koch (Hemiptera: Aphididae) and a predator, the zigzag beetle Cheilomenes sexmaculata (Fabricius ...

Host choice and host leaving in Rhopalosiphum padi (Hemiptera: Aphididae) emigrants and repellency of aphid colonies on the winter host [PDF]

open access: yes, 2000
Host choice and winter-host leaving in emigrants of bird cherry–oat aphid, Rhopalosiphum padi (Linnaeus), were investigated in the laboratory. In settling choice tests, emigrants collected from the winter host, Prunus padus, preferred this plant over ...
