A landscape view of cereal aphid parasitoid dynamics reveals sensitivity to farm- and region-scale vegetation structure

European Journal of Entomology, 2008
Functioning of plant-aphid-natural enemy interactions may be associated with the structure and composition of withinfield vegetation, neighborhood fields and field borders, and the regional plant community of cropped and noncropped areas.

Complete mitochondrial genome of the witch-hazel leaf gall aphid Hamamelistes spinosus (Hemiptera: Aphididae: Hormaphidinae)

Mitochondrial DNA. Part B. Resources, 2020
We sequenced the complete mitochondrial genome of Hamamelistes spinosus using the shotgun genome-skimming method. The mitogenome of H. spinosus is 15,089 bp in length with a much higher A + T content of 81.8% than that of G + C (18.2%) and consists of 13

Bacteriophage effect on parasitism resistance [PDF]

arXiv, 2022
Many studies have shown that the protection of the host $\it{Acyrthosiphon~pisum}$ (Hemiptera, Aphididae) against the parasitoid $\it{Aphidius~ervi}$ (Hymenoptera, Braconidae) is conferred by the interaction between the secondary endosymbiont $\it{Hamiltonella~defensa}$ and the bacteriophage $\it{APSE}$ ($\it{Acyrthosiphon~pisum}$ secondary ...

Urban greenery aphids (Hemiptera, Aphididae) [PDF]

Archives of Biological Sciences, 2013
In 2010-2011, a study of the occurrence of aphids was carried out in three parks in Bydgoszcz, the Balaton Park, the Jan Kochanowski Park and the Park by Unii Lubelskiej. Observations were made every ten days by monitoring trees and shrubs as soon as aphids appeared, i.e. from the end of April to the beginning of August.
